Thermal boundary conditions based on field modeling of fires Heat transfer calculations in CFD and FE models with special regards to fire exposure represented with adiabatic surface temperatures
Sammanfattning: Combining computer fluid dynamic, CFD, models with finite element, FE, models to calculate temperature in fire exposed structures can reduce design temperatures in structures while still obtaining the level of structural fire safety stipulated by society. A better understanding of heat transfer and the concept of adiabatic surface temperatures, AST, the transition of data between models can be simplified and more accurate temperature predictions can be made. The thesis focuses on heat transfer calculations by employing AST in particular, and how this can be used as a means of coupling any CFD and FE-analysis code. The thesis presents a method for performing FE-analysis of the thermal response with input data calculated with the computer code FDS, Fire Dynamics Simulator. Parallel to this, the heat balance equation in FDS is tested and an alternate numerical algorithm is developed and tested. Firstly, a verification model is developed to test the radiative and convective part of the existing heat balanceequation in FDS. An alternate numerical algorithm for calculation of the heat transfer at surfaces is developed as a more homogenous alternative for CFD codes. Secondly is a study on how to extract AST from an arbitrary point with direction in a CFD calculation using an infinitesimal surface. Instead of modeling numerous small surfaces for extracting AST, a post processor is developed to calculate AST independent of any modeled surface. For CFD codes, such as FDS that depend on a rectilinear grid, this enables calculation of AST in any direction, not only directions normal to the Cartesian planes. Finally, a comparison is made between different methods for calculating temperatures in steel with AST from numerical fire dynamics/modeling calculations. In this thesis there is a comparison between simplified Eurocode techniques, simple finite element analysis and advanced finite element analysis. This study shows the benefit of understanding heat transfer in numerical codes and to implement the concept of AST in a proper way. This way, the concept of combining numerical fire dynamics calculation with numerical (or simplified) thermal calculations can be better understood and implemented.

The Spokane Airport Board has developed a new master plan for Felts Field that calls for extension of the primary runway, adding new hangars, and replacing the air traffic control tower at the 400-plus acre general aviation airport in East Spokane.
The master plan was completed by New York-based aviation consulting group WSP USA and funded through a $680,000 grant through the Federal Aviation Administration, says Todd Woodard, director of marketing and public affairs for Spokane International Airport via email correspondence.
WSP recommends in the master plan that Felts Field’s 4,500-foot-long primary runway be extended by 1,000 feet. The consultant also recommends adding 32 new hangars at the airport.
Woodard says the airport board intends to pursue funding to extend taxiways to 13 acres of undeveloped land north of the airport that supports future hangar development.
The master plan also calls for replacing the air traffic control tower by 2037. The current 67-foot-tall air traffic tower isn’t tall enough to meet line-of-sight requirements, and it also isn’t compliant with the Americans with Disabilities Act.
WSP recommends relocating the tower to address the line-of-sight issues. By relocating the air traffic tower to a more strategic location, the airport will be able to use about 3 acres of land at the current tower site to accommodate about 26 small to midsize hangars, the consultant advises.
The goal of the master plan, airport officials say, is to focus on updating facilities at Felts Field in order to encourage general aviation aircraft to use Felts Field instead of Spokane International Airport. As a general aviation airport, Felts Field provides an alternative site to operate noncommercial aircraft.
The primary runway extension isn’t planned for another seven to 10 years. Meantime, the airport board is planning a full restoration of the current runway, including lighting by 2025, says Woodard.
He declines to estimate the cost of the proposed improvements, and funding hasn’t been finalized, although he says the airport board is in discussion with the FAA regarding potential funding.
“The investment is unpredictable as it will depend on the availability of grant funds,” says Woodard of the envisioned capital projects.
The last major item on the master plan is renovating the terminal, an Art Deco building, which was constructed in the 1930s.

Guidelines for sustainable NYC parks released
The NYC Department of Parks & Recreation and the Fellows of the Design Trust for Public Space have prepared and released a manual called “High Performance Landscape Guidelines: 21st Century Parks for NYC.” It’s a comprehensive design and construction manual for sustainable parks and open spaces and will henceforth guide the design, construction and maintenance of New York City parks, in alignment with Mayor Bloomberg’s PlaNYC 2030.
The “Guidelines” will ensure that NYC’s parks clean our air and absorb storm water, reduce the urban heat island effect, provide habitat, and address the challenges of climate change. This manual contains hundreds of best practices including:
- Keeping rain water within parks for the use of plantings rather than sending it to sewers.
- Increasing the resiliency of plantings by considering the soil, the effects of climate change, the plant type and future maintenance needs.
- Designing to save labor, reduce operating expenses and decrease the frequency of capital replacement.
This is a fantastic guide specifically for New York City parks, but would also be useful to any parks system interested in integrating sustainable practice into the core of its operations. There is also a great section of case studies at the end of the document that features the ecological restoration of Pennsylvania and Fountain Avenue Landfills, Bronx River tidal marsh restoration efforts and the 5 Boro Green Roof complex, among other projects.

It’s not often we get to look at the inside of a home when it comes to glazing material.
And even more rarely, it’s not a matter of when, but how many coats of glazing are needed for a particular home.
The best glazing materials are designed to last, and when you have a home that is going to be a work of art for years to come, the most important thing to know is how to make sure it will last for years.
The basic premise of glazes is that they’re used to cover up imperfections and to prevent air from entering the home.
When you put a glaze over a surface, it creates an even layer of air that absorbs moisture and helps keep your home in the winter months dry.
In a typical house, the glaze layer would cover the entire floor, which is why it can be a bit of a hassle to get all the glazing you need.
The glaze would need to be made with the correct material to be effective, and the right coat of glaze is crucial.
But the materials we’re going to use to make our Glazing are not all that different from the ones you’ll find in your typical home.
There are several different types of glazed surfaces you’ll need for a home, but we’re starting with the simplest type: the concrete floor.
The concrete floor has many different uses.
The most common use is for exterior finishes like roofing, so you can build a simple roof for your home or even use it as a base for other structures.
When concrete floors are used for exterior finish applications, it helps to understand the different types that are available.
The main difference between a concrete floor and a wood floor is that concrete floors can be used on a wood foundation.
Wood flooring, however, doesn’t have as much of a need for glazing.
You can use a concrete foundation on a wooden foundation to build a brick wall, or you can use concrete to build the walls of your home.
While concrete is a good material for interior walls, there are other types of concrete that you can choose from that can also be used as a building material.
Here are some of the more common types of home glazing that you’ll want to look out for when you’re building a home:Glazing for interior and exterior finishesThere are two types of interior glazing: concrete and wood.
Both of these materials can be made into glazing depending on the purpose.
While a wood glazing can be applied to the walls to create a finished look, a concrete glazing is used for interior finishes and to protect surfaces from moisture and insects.
To make concrete glazed walls, concrete blocks are mixed with concrete to make a solid block.
This concrete is then poured onto the walls and the glazed wood is then glued to the concrete.
A typical home glazed floor is made from concrete blocks, but you can also use other types like plywood, plastic, and ceramic.
You’ll also want to take a look at whether a wood or concrete glaze has the right kind of surface finish to protect your home from bugs and pests.
If you choose a concrete or wood glazed exterior, you’ll also need to consider the type of finish that you want to use.
There’s no right or wrong way to choose the type or color of exterior finish, but there are a few things to consider:You can choose a material to glaze your home that’s durable enough to withstand weather and mold.
This is a material that won’t need any more than regular use, and is the type you’ll most likely need to use for exterior and interior finishes.
This type of gliding material will last much longer than regular glazing and won’t become moldy or chip when exposed to moisture and molding.
If you have to, you can add glazing to the roof of your house, but most homes aren’t going to need it.
If your home has a concrete roof, you won’t have to worry about moisture damage and the roof will still be protected from moisture, so the extra cost isn’t worth it.
If your home is on a timber flooring system, you might not want to add a coating to your home, either.
Wood floors have a very high rate of moisture loss, and wood floors don’t have the same level of protection from moisture as concrete.
If wood floors aren’t the type that you’re looking for, you should probably look into some other material for your glazing needs.
You may be able to find wood floors that are even more durable than concrete, but if you want a durable glazing option for your roof, this might not be the material for you.
Glazing on exterior finishesWhile glazing on your exterior finishes is a nice addition to your interior glazed home, you don’t want to neglect it if you’re planning to move in. When


Paving can refer to numerous forms of constructing development. Paving can embrace repairing of driveways, walkways, driveways, ramps, terraces, driveways, parking lots, garages, sidewalks, swimming pools, fireplaces, porches, decks, driveways, patios, stairs, porch, fences, basketball courts, tennis courts, horse arenas, golf courses, basketball courts, tennis courts, awnings, retaining walls, fences, telephone strains, cable wires, phone poles, pipelines, fuel and oil pipelines, electrical lines, septic tanks, gas strains, sewer lines, and telephone strains. Paving may also discuss with the decorative arts akin to brick, concrete, marble, slate, concrete pavers, wooden, sand, gravel, brick and paving bricks. The paving of a public place will be achieved using varied types of fabric. However, before paving a public place, there are several elements to consider akin to utility and legal responsibility considerations, local ordinances, safety necessities, aesthetics, price, visitors, and utilities.
If you beloved this article so you would like to receive more info relating to paving contractors nicely visit our web site.
Paving of a paved floor includes the usage of a mixture of aggregate, gravel, stone and different stones to create the material that stands between the pavement and the surrounding soil. Aggregates are any material that may be compacted right into a single mass. Gravel is any material with coarse and superb grains. Other paving supplies can embody asphalt, decomposed stone, decomposed peat, screed stone, sand, clay and limestone, granite, quartzite, and decomposed ash. Before paving a paved surface, the area must be adequately prepared by removing topsoil, leveling, planting grass, and using a weed barrier.
Aggregate supplies are the most typical part of paving slabs. These aggregates are made by grinding stone or plastic till they turn into coarse sufficient to be suited to be used as paving slabs. They’re then crushed additional to type wonderful particles that are mixed collectively. The ultimate product is named stone. These paving slabs have good durability properties as a result of they are dense, agency, and the spectacular quality of the stone permits it to resist indentation, recession, cracking, and crumbling.
There are three sorts of materials generally used in paving slabs; pure stone, clay, and paving slabs made from plastic. Natural stone is the most commonly used material in paving. This consists of marble, granite, limestone, slate, travertine, onyx, and other volcanic, limestone, and dolomite stone. In addition to getting used as materials for paving slabs, natural stone can also be used as patio pavers and in exterior and inside decorations.
Clay pavers are compact, lightweight, water-resistant, and heat and stain resistant. Clay slabs are most commonly used for inlaid decorative pathways, driveways, sidewalks, plazas, and patios. Quarry clay pavers are the most commonly used kind of clay paving slabs in North America. Quarry clay, or purple clover as it is more commonly recognized, contains similar chemical and physical traits to stone however is extra reasonably priced. It can also be used to pave the ground for bigger initiatives.
Another commonly used materials in paving is asphalt. Asphalt is a very heavy responsibility paving material that’s finest fitted to paved walkways and driveways. It’s also generally used to construct sidewalks. Unlike clay or stone pavers, asphalt doesn’t crack or crumble simply. Because of its gentle weight and water-resistant nature, asphalt is a good choice for maintenance and repair tasks.
There are some elements to consider when buying individual models of paving slabs. A serious consideration is the amount of paving materials that can be required for the challenge. Individual items of paver could also be purchased in numerous quantities. To calculate the fee of every individual unit of paver, it is necessary to multiply the variety of paver slabs by the variety of pavers required for the challenge. This cost can then be divided by the quantity of individuals needed to install the paving units.
Paving with paving bricks is an efficient resolution for small to medium projects. It is relatively cheap and gives many advantages together with sturdiness and security. The professionals and cons of utilizing these two kinds of paving bricks are the identical as those of using sand and gravel. All of it is dependent upon the venture, funds, and the preferences of the homeowner or builder. Paving with sand is a well-liked choice particularly in areas with little to no development while paving with bricks is extra price-efficient for big initiatives.

Regardless of the features of the terrain, any plot intended for building a house requires vertical planning. What is its essence and why is it needed? Vertical layout of a site is an artificial transformation, improvement and change of a relief. The main purpose of this planning is to create a surface that would meet all the requirements for the improvement of the territory. As a rule, the vertical planning implies a cut of the seams of the earth, the organization of gutters, the laying of tracks, the softening of the natural relief, the sprinkling of soil, etc. Now, let us consider the most common examples of the relief layout.
Vertical planning of the territory does not require large expenditures from owners of horizontal sites. In addition, such a relief of the plot gives a wide choice for the future orientation of the house, the location of green spaces and farm buildings. In this case, it will be necessary to create small local deviations near the walls of the building. The mentioned slopes are made with the usual subsoiling of the soil. On the perimeter of the site, shallow grooves are digged, leading them out of the site. This must be done along the edges of the tracks. It is worth noting that these works are necessary for any relief.
If the future house is located on the southern slope, it is worth considering the creation of a garden or garden. The house is best located at the top of the slope. As for the hozpostroek, they are usually placed at the bottom of the site. Vertical planning with the described relief is very similar to the layout of the horizontal platform.
On the western and eastern slopes the house should be located near the northern border of the site, so it will not overshadow the planting. Also behind the house you can create a garden, because fruit trees have a sufficient height and do not suffer much from the shadow cast by the structure.
Special efforts will require vertical planning when the site is down to the north or steep slope (more than 20 °). After all, during the rain on steep slopes, strong water currents form, eroding the soil. And on the northern slopes, plants do not have enough sun, and as a consequence, they grow poorly. Under such circumstances, there is only one way out: break the site into several horizontal terraces, which will create better conditions for the plants and preserve the soil from erosion.
Such terraces are formed by padding soil, creating a strip-strip, which are perpendicular to the direction of the slope. With these works, the slopes of the terraces can be strengthened with large stones, turf or masonry on cement mortar. Plates of the turf will not slip off the slopes, if they are strengthened with wooden pegs. When decorating slopes with stones, the latter should be densely laid in prepared grooves. The base of the slope must consist of large stones, and the upper part - of smaller ones. The drainage grooves should be placed along the edge of the terraces, then the water streams will not erode the slopes. The house on the northern slope is best located at the bottom of the site, near its western border. When the vertical planning is completed, you can proceed with the breakdown of the house plan.

Hope boosts cement rail transport with £1m wagon investment
Published: 22 May, 2015
Hope Construction Materials has announced a major investment in rail transportation from its flagship Derbyshire cement operation.
The independent supplier of construction materials is investing over £1m in the manufacture and long-term lease of 48 tailor-made rail wagons for the distribution of cement from its Hope Works, in Hope Valley.
The wagons are being manufactured by German company Feldbinder, and are due for delivery to Hope Works in the autumn of 2015. Once in use, they will improve Hope’s ability to consistently transport over a million tonnes of cement from its plant to depots, including Theale near Reading, Dewsbury near Leeds and Walsall, for onward road deliveries.
In keeping with the firm’s ongoing commitment to improving sustainability, the wagons will be built from aluminium, reducing weight and with it, fuel consumption and carbon emissions. The wagons will also be quieter than other models, utilising track-friendly bogeys which allow the wheels to turn around bends more easily.
Ashley Bryan, industrial director at Hope Construction Materials, said: “These new wagons will bring many benefits and help us achieve major improvements in our rail logistics operation.
“They will carry a much larger ‘payload’ – 80 tonnes in comparison with the current wagon payload of 36 tonnes – meaning fewer trains are required to achieve the same annual volume, resulting in reduced movements up and down the branch line between Hope Works and the mainline.
“Fewer rail movements mean less impact on our neighbours around Hope Works which is very important to us given our commitment to maintaining a strong relationship with the local community.
“The improved wagon design also makes it easier for our operators to load and discharge cement, resulting in reduced manual handling.”


Crumbling stone steps may look time-worn and quaint but they are a serious hazard. An uneven, damaged step can cause someone to miss her footing. A slip or fall can then result in serious injury. Mending such steps is a sensible option, but you need to proceed with care. A clumsily applied cement or concrete repair can soon deteriorate and prove to be a risk in itself. Instead, you should use an alternative that restores crumbling stone steps to their former solid finish.
Recent Crumbling Stone
Find a repair mortar to use on stone steps that have recently started to crumble. Proprietary mortars designed specifically for stone repairs contain tiny pieces of crushed stone that bond together to create a robust finish.
Follow the manufacturer’s instructions and add cement and sand to the repair mortar. Add water and mix well.
Ensure the stone steps are clean and free of dust. Dampen them. Apply the repair mortar with a trowel and leave a smooth finish. Do not apply in thicknesses of more than 40mm. If you need to build up the steps to a greater thickness than 40mm, use separate coats.
- Find a repair mortar to use on stone steps that have recently started to crumble.
- If you need to build up the steps to a greater thickness than 40mm, use separate coats.
Apply a light mist of water to the repair mortar two times a day for a week. If the weather is particularly hot, apply the light mist of water more often.
Repair the treads of badly-worn stone steps with fresh slabs of stone. Measure the treads and ask a stonemason to cut suitable stone to the right size. You may need a stonemason to first check the steps to assess the type of stone and colour.
- Repair the treads of badly-worn stone steps with fresh slabs of stone.
- Measure the treads and ask a stonemason to cut suitable stone to the right size.
Chisel the treads to remove the worn surface. Cement the new stone treads in place. Use a mortar mix of one part cement to two parts sand. Sieve the sand first so that it’s as fine as possible. If the steps are dry, dampen them before applying the mortar.
Replace worn stone risers in a similar way to treads. Ask a stonemason to cut stone to match the size of the risers. Chisel the worn risers to produce an even surface. Fix the new stone risers in place with a cement and sand mix as above.
Use new risers to provide additional support to new treads. In this instance, the stone of the new risers doesn’t need to be as thick as the treads. To create slightly deeper and safer treads than those of the original stone steps, allow the treads to project beyond the risers by 16mm.
Always wear a face mask when working with stone. The dust can affect your nose, throat and lungs.


Tankless water heaters heat water directly without the use of a storage tank. When a hot water tap is turned on, cold water travels through a pipe into the unit. Either a gas burner or an electric element heats the water. As a result, tankless water heaters deliver a constant supply of hot water.
What is the cheapest way to heat hot water?
Usually natural gas is the cheapest way to heat water, followed by electricity, with propane being the most expensive.
How can I heat the water in my house fast?
How to Get Hot Water FasterInsulate the Pipes. If you think your water pipes are to blame for your hot water troubles, adding insulation might improve your situation. Hot Water Recirculation Pump. Replace Fixtures with a Higher Flow Rate. Upgrade to a Tankless Hot Water Heater. Routine Preventative Maintenance.
What can I use instead of a water heater?
A heat pump water heater uses one-third to one-half as much electricity as a conventional electric resistance water heater. In warm climates they may do even better. Households using electric water heating and a heat pump for space conditioning can reduce water heating costs by installing a “hybrid” heat pump system.

Does hot water heater use a lot of electricity?
But your hot water heater uses a lot of energy. Water heating systems are the second biggest user of electricity in your home. This is on average 18% of your electricity costs, according to the U.S. Department of Energy.
What is the most energy-efficient way to heat water?
Generally speaking, modern combi boilers are more energy-efficient than a hot water heater system with a tank or cistern. There are several other ways of water heating, including solar hot water systems, immersion heaters, electric water heaters, electric showers and, of course, kettles.
How do I make my shower water hot again?
1:312:51How to Make Your Shower HOTTER! - YouTubeYouTube
How do I get more hot water out of my water heater?
Tempering Valve: If your current water heater is fairly new, well insulated, and in good condition, adding a tempering valve (aka. mixing valve) to your water heater can soup up your hot water capacity. After the device is installed, the water temperature in the tank can be increased well above the normal setting.
How long does it take for a water heater to heat up?
between 30 and 40 minutes The average gas heater takes between 30 and 40 minutes to fully heat up the water in its tank. The average electric heater takes about twice as long as the average gas heater to fully heat up the water in its tank, so you can expect it to take between an hour and an hour and 20 minutes to heat up.
Where can a gas fired water heater not be located?
Installation of the water heater must be accomplished in such a manner that if tank or any connections should leak, the flow will not cause damage to the structure. For this reason, it is not advisable to install water heater in an attic or upper floor.
What is the lifespan of a hot water heater?
about eight to 12 years Based on the manufacturers suggested service life, the life expectancy of a water heater is about eight to 12 years. That varies with the location and design of the unit, quality of installation, maintenance schedule and water quality.
Is it cheaper to heat water with gas or electric?
Gas is much cheaper than electricity if you are using it to heat the same amount of water. But some immersion heaters only heat water at the top part of the tank, so if that sometimes only once a week demand for water is just for a small amount, the immersion heater could still be cheaper to run!
Is it cheaper to keep hot water on all the time?
It is a myth that leaving your hot water on all of the time will save you money. Unless you need a constant supply of warm water, your boiler will be constantly heating when there is no real need. It is cheaper and more energy-efficient to switch your boiler on, only when you need the hot water.
Why is shower water not hot enough?
The reason why youre not getting enough hot water from your shower could be because the mixing valve isnt working. The rubber parts found in the mixing valves get worn down over time, and you will need to replace it.
Why is there hot water everywhere but my shower?
If youre getting hot water everywhere but your shower, it could be that your anti-scald device is set at too high a limit. Its basically a “stopper” that limits how far your shower handle can rotate in the hot water direction.
Does turning up water heater make hot water last longer?
Turn up the thermostat on the hot water heater. One of the easiest ways to make a hot shower last longer is by using less hot water while its at a higher temperature. To do this, turn up the temperature on the thermostat thats attached to the hot water heater tank. Be conscious of other hot water in your home.
How long of a shower can you take with a 40 gallon water heater?
A 40-gallon water heater can provide up to 2 showers in an hour (if youre not using any other water appliances).

The offshore wind industry is growing rapidly and will become an important sustainable energy source in the coming decades. Although the energy is clean, there are still important environmentally harmful elements associated with offshore wind farms. These are, however, relatively easy to solve. During the construction phase, which takes normally between 8 and 18 months, diesel generators are used to supply energy to these structures. So called sacrificial anodes and coatings are also used to prevent corrosion. The use of diesel generators is not only expensive, but also harmful to the environment. The emission of harmful gases and leaks during refueling create substantial and unnecessary pollution of the immediate environment. The coatings and anodes protect against rust but are also broken down so that harmful
substances are released into the environment.
This Dutch SME offers an alternative to these unnecesarry polution and harmfull substances. Together with a partner they developed sustainable energy system that runs on sun wind and batteries that combines an anti corrosion method which is a sustainable alternative to sacrificial anodes and expensive coatings to prevent corrosion.
The sustainable solution is to use the energy system in combination with the anti corrosion technology during the construction phase. After the large wind turbine has been installed and grid connected, it can supply energy to the anti corrosion system itself. During the construction phase the energy stem generates its own energy and protect the structure against rust and degradation. The owner can therefore save substantial costs because no or only a light coating is sufficient since the structure is protected against corrosion from the very beginning.
In addition, the system can also be equipped with basic facilities, such as toilets and first aid cases, which support the basic health and safety aspects during the construction and service phase.
The company is looking for partners active in the construction of windfarms to implement this technology into their work process in the framework of a commercial agreement with technical assistance.

As demands upon available water supplies increase within a river basin, there is an accompanying increase in the need to assess the downstream consequences resulting from changes at specific locations within the hydrologic system. This problem is approached in this study by digital computer simulation of the hydrologic system. Modeling concepts are based upon basic relationships which describe the various hydrologic processes. Within a hydrologic system these relationships are linked by the continuity-of-mass principle which requires a mass balance at all points. Spatial resolution is achieved by considering the modeled area as a series of subbasins. The time increment adopted for the model is one month, so that time varying quantities are expressed in terms of mean monthly values. The model is general in nature and is applied to a particular hydrologic system through a programmed verification procedure whereby model coefficients are evaluated for the particular system. In this study the model was applied to the Provo River basin of northern Utah, with emphases being placed upon water rights and operation of storage reservoirs within the system, including Utah Lake. The simulation model consists of three specific parts, namely: (1) parameter optimization; (2) river basin management; and (3) Utah Lake operation. The parameter optimization submodel identifies the model parameters for each subbasin through application of a parameter optimization technique. The river basin management submodel, using the optimized parameters, simulated the hydrologic response of the system to various water resources management alternatives. The Utah Lake operation submodel is linked with the river basin management submodel to comprise a combined Utah Lake operations model. Some comparisons between observed and computed outflow hydrographs at various points within the Provo River basin are shown. The utility of the model for predicting the effects of various possible water resource management alternatives is demonstrated.

|National Highway 53 has deteriorated, resulting in cracks and subsidence, which could lead to accidents. — Photo vfpress.vn|Viet Nam News
TRÀ VINH — Project Management Unit 7 under the Việt Nam Road Administration has proposed that the Ministry of Transport upgrade part of National Highway 53 and build an additional road.
Total investment for the project is VNĐ1.46 trillion (US$65.4 million).
As planned, the road will be 52.5km in length and 12m in width, connecting Châu Thành District’s Hoà Thuận Commune and Duyên Hải District’s Duyên Hải Township.
Two bridges in Nhị Trung and Lộ Đá will be built along the road.
The construction of an additional road, which will run parallel with the highway and pass through Trà Vinh City, will ease traffic overload and meet transport demand.
This road will be 9.5km in length, starting at the intersection between National Highway 53 and 60 in Trà Vinh Province and ending at Châu Thành District’s Duyên Hải Township.
Four bridges will be built along the road.
Investment capital will be mobilised from the state budget and state bonds.
Report of the Việt Nam Road Administration’s survey on traffic flow this August showed that there were more than 2,550 vehicles travelling on National Highway 53 each day. The road has deteriorated, resulting in cracks and subsidence, posing the risk of traffic accidents for commuters.
Currently, National Highway 53 is the only road connecting southern Trà Vinh Province to National Highway 1A and the Mekong Delta provinces. The project will reduce traffic jams and accidents on the route and boost socio-economic development and national defence in the Mekong Delta region. — VNS

A 3.5-year PhD research project in the Department of Geography and the Institute for Hazard Risk and Resilience at Durham University. Supervised by Dr. Sim M. Reaney, Prof. Richard Hardy and Dr Isabella Bovolo
Background Flood hazards in Nepal have resulted in significant regional impacts in recent years. Nepalese floods in August 2017 affected over 1.7 million people; 461,000 people were displaced, 159 people died and 65,000 houses were destroyed (UN RC 2017) making the event one of the worse in recent years. One widely employed method of risk transfer is the use of insurance to cover the losses incurred during flood events. The normal approach is to determine the probability of a flood event occurring at a location through hydraulic modelling and the associated damages from a depth-damage curves developed for that specific location. However, in data poor regions (such as Nepal), there has not been the information required to develop and test these models. Recent innovations in remote sensing and simulation modelling have enabled existing quantitative approaches to be rolled out more widely. The results have the potential to be coupled with new approaches to flood insurance to enable the sale of risk transfer insurance products to new communities at affordable prices. To operationalize this aspect of the research, there are still several challenges associated with determining the flood hazard and the potential for errors which can significantly affect people’s lives.
Aims and objectives The aim of this PhD research project is to determine flood hazard patterns in Nepal using remote sensing and simulation modelling. This research aim will be addressed with the following objectives: O1: To undertake spatial flood water source mapping and identification of vulnerable communities to determine case study catchments. O2: To determine temporal changes in flood hazard magnitude and frequency for a set of case study catchments. O3: To produce spatial patterns of flood risk determined by various terrain datasets and performance assessment approaches. The project will take a wide view across the different catchments in Nepal to determine the spatial pattern of flood water generation at the national scale. Findings from this research will feed into new technologies for financing disasters with colleagues in Durham University Business School.
Methods The broad scale mapping work will use the SCIMAP-Flood approach to determine the likely origin of the flood waters. This approach uses rainfall information, such as from TRMM coupled with on the ground rainfall records, topographic data to determine the hydrological connectivity and land cover information to determine the runoff coefficient from each location. This information set is integrated to give the catchments with the greatest amount of flood water generation across Nepal. This information will then be combined with information on communities at risk from flooding to determine a set of three case study catchments for more detailed analysis. To determine the flood hazard generation for each of the identified catchments, the project will apply hydrological simulation modelling techniques. The research will consider the trade-off between conceptual lumped catchment simulation models, such as HBV, and full spatially distributed process-based models, such as CRUM3. Each approach will be limited by the availability and quality of the rainfall and river discharge records and hence novel approaches to model assessment may need to be developed make best use of the datasets. Targeted field work to install monitoring equipment and undertake key hydrological measurements may be undertaken to support this work. The models will be run for both current climate conditions based on observed data and for projected climate change to determine the magnitude and frequency of flood events in the future.
The final section of work will consider the inundation pattern within effected communities based on an understanding of the uncertainties in the estimation of the magnitude frequency relationship and the topographic dataset used. The inflow hydrographs will be based on the different catchment models and an ensemble of flood events will be used to drive a 2D hydraulic flood simulation model, such as HEC RAS 2D or Flood Modeller Pro. The topographic data is key in determining the performance of the flood inundation model and the PhD will test the effectiveness of a range of data products. These will range from published datasets, such as the 30m ALOS data, the commercially available AW3D 5m data and detailed data based on photogrammetry since LiDAR is not available. These detailed datasets will be created from the Structure from Motion approach using source images from existing helicopter surveys and targeted drone flights. The helicopter sourced data can give ground resolutions of ca. 0.5m and the drone data can give resolutions of 0.1m. To determine the benefit of the more detailed, but more expensive data, the flood inundation model performance will be assessed against known events to determine the fit between the observed and the simulated flood extents. The database of known events will be determined using geomorphic evidence from past flood events using remote sensing products and on survey data in collaboration with other researchers at Durham. The before and after data sets will be based on open access Landsat and Sentinel data and the commercial Planet Labs daily imagery. The Landsat and Sentinel data may be able to give information on the maximum extent of the flood events but the daily Planet Labs data has the advantage of being able to potential capture the flood in progress, giving more information to assess the performance of the flood model.
Research outcomes At the end of the research project, there will be the understanding and evidence to recommend a spatial flood hazard mapping method for Nepal. This approach will include recommendations as to how to make the best use of the available data and which additional datasets would have the greatest improvement on the hazard mapping. The climate change work will allow for an understanding of the potential changes in flood hazards over the 21st century. This information will be integrated into future work on providing flood insurance to the at-risk communities in Nepal and beyond.

When a signaling system reaches its end of life, an overall replacement is necessary. The replacement may be in-kind but for many mass transit agencies, it is common that capacity needs will have grown significantly, and the transit agency is required to increase capacity while tackling obsolescence. Capacity and obsolescence are the primary reasons for deploying Communications Based Train Control (CBTC) technology to replace conventional trip stop and track circuit-based systems operated by New York City Transit (NYCT) or cab signaling systems operated by Baltimore Maryland Transit Administration (MTA) and the San Francisco Bay Area Rapid Transit District (BART). Resignaling projects are often refereed as brownfield train control projects.
Due to the technical and commercial complexity, the quantity of stakeholders, the number of interfaces, the regulatory involvement via safety certification, the temporal and geographic scale of the project and the continual evolution of the existing system, a robust Systems Engineering (SE) process is necessary to achieve success in large signaling replacement projects.
This paper describes the software tools and processes that were deployed to meet the technical, legal and commercial needs of a large signaling replacement project during the specification development phase. The processes put in place were tailored to the size and location of the team members. The paper describes the software tools, such as IBM Rational DOORS, Microsoft SharePoint Online and Office 365 which were integrated and configured to allow for collaboration while accounting for the security, commercial and legal requirements of the agency. The selection, deployment and management of these processes and tools enabled the large, complex project to succeed.


New System Offers Simplified On-Line Ammonia Monitoring
The US historically uses both groundwater and surface water as a source of drinking water.
by John Becker adn Michael Strahand
The US historically uses both groundwater and surface water as a source of drinking water. In addition to concerns over the availability of groundwater, there can be significant issues with water quality when groundwater and surface water are mixed. Most surface water treatment plants use chlorine as a disinfectant, while chloramine is often used for the disinfection of groundwater for drinking water.
When groundwater and surface water mix in the distribution system, the chlorine and chloramine disinfectants combine to form a residual substance which contains ammonia, free chlorine and monochloramine. As a result of the increasing combination of surface water and groundwater, it is essential that water treatment plants are able to carry out accurate monitoring of these chemicals in water to avoid any potential health consequences.
Ammonia monitoring has traditionally been undertaken by automated versions of ammonia-selective ion electrodes, but these methods are geared toward laboratory applications. These conventional systems generally use expensive and complex instruments which are difficult to maintain and often require external service contracts.
Technology recently introduced to the water market offers a completely new approach to simultaneous on-line monitoring of chloramines and ammonia which is simpler, cheaper and more stable than conventional monitoring equipment. With this technique, measurement of both ammonia and chloramine can be carried out on one instrument.
The technique has been adopted by Analytical Technology Inc. (ATi) and is incorporated in its new Q45N Dissolved Ammonia Monitor. The system uses reaction chemistry to convert ammonia in a solution to a stable monochloramine compound, equivalent in concentration to the original ammonia level. The chloramine concentration is then measured with a unique amperometric sensor that responds linearly to chloramines while eliminating interface from excess free chlorine in solution.
Much cheaper than conventional monitors, the new technology has the added advantage of allowing direct re-injection of the water withdrawn for monitoring purposes back into the distribution system without the need for discharge to a sewer. Maintenance of the new monitors is simple and can be managed by utility staff. The new Q45N monitor can also be used with ATi’s free chlorine monitor to provide measurement of free chlorine, chloramines, free ammonia and total ammonia.
The Q45H monitor provides reagent-free measurements of free chorine in water and wastewater applications.
The Q45N system consists of a wall mounted chemistry system and an electronic display and alarm package. The chemistry system contains the necessary metering pumps to provide chemical addition to the sample and delivery of the sample to the sensing element. The electronic display and alarm package provides the user interface to the system. Ammonia concentration is displayed on a large format LCD display with secondary display for other operating variables.
In 2003 the State of Texas mandated that the amount of groundwater consumed by municipalities should be cut, as aquifers cannot be recharged quickly enough to meet the state’s increasing demand for water. In setting out these groundwater protection goals, the authority specified that wherever possible, surface water should be used instead. Since 2003, 51 districts have adopted water management plans, including a water utility which serves the Houston area.
The ATi Q45N free ammonia monitor can be combined with the Q45H free and combined chorine monitors to enable measurement of free chlorine, chloramines, free ammonia and total ammonia
The water utility monitors water on both incoming and outgoing streams in order to determine levels of ammonia, chloramines and free chlorine. One panel of the treatment system contains the Q45FN ammonia monitor and a Q45H/62 free chlorine monitor. Each of the water utility’s sites requires two panels, and each storage facility has a booster system to reinstate the disinfectant level when the two types of water mix, thereby ensuring that drinking water is properly disinfected and free from potentially harmful reagents. By using this technology, the water utility has lowered the overall cost of ammonia monitoring.

There will be a scheduled water service interruption on Thursday, Aug. 18, 2022, from 8am to 4:30pm for Commonwealth Utilities Corp. customers in portions of Fina Sisu (Joeten Subdivision, Gafo Place, Tun Joaquin Doi Road, Ghoot Lane to Bayak Drive). Customers in the affected areas will experience low water pressure to no water during the outage period.
The scheduled water service interruption is to allow CUC’s contractor for the Fina Sisu Waterline Replacement Project to tap and connect the new PVC waterline to the existing 4-inch PVC main waterline along Tun Joaquin Apa Road and to cap the existing PVC pipe that is to be abandoned. Customers should expect normal water service soon after.
This project is part of the Fina Sisu Waterline Replacement Project funded by U.S. Environmental Protection Agency, to provide a more reliable water system. The transition work is in part of the decommissioning of the old waterline to eliminate risks of contamination and frequent line breaks.
