## 🌊 Overview

**TSU-WAVE** is a physics-based framework for real-time analysis of tsunami wave front evolution, energy transfer dynamics, and coastal inundation forecasting. It integrates **seven hydrodynamic parameters** into a **Composite Hazard Index (CHI)** that enables operational coastal warning centers to issue alerts up to **67 minutes before landfall**.

The system is validated against **23 documented tsunami events** spanning a **36-year period (1990–2026)**, across propagation distances of 180 km to 14,200 km, and verified against **712 field-measured run-up points** from the International Tsunami Survey Team (ITST) database.

```
Seismic Source → NSWE Propagation → Bathymetric Modulation (BECF)
              → Front Stability Tracking (HFSI)
              → Spectral Energy Analysis (SDB, KPR)
              → Shoreline Boundary Resolution (SBSP)
              → Micro-Vorticity Correction (SMVI)
              → CHI Composite Index → Run-up Forecast + Alert
```

### Why TSU-WAVE?

| Existing Systems | Limitation | TSU-WAVE Solution |
|---|---|---|
| DART buoy arrays (NOAA) | Open-ocean only, no shelf dynamics | Full propagation path integration |
| Tide gauge networks (GLOSS) | Point measurements, no wave geometry | 7-parameter front evolution tracking |
| Linear codes (MOST, TUNAMI-N2) | Omits nonlinear shoaling | Nonlinear NSWE solver |
| Satellite altimetry (Jason-3) | 10-day repeat cycle | Real-time 1-minute resolution |

---

## 📈 Performance Metrics

| Metric | Value |
|--------|-------|
| **Run-up Prediction Accuracy** | **91.3%** |
| **Threat Detection Rate** | **96.4%** |
| **False Alert Rate** | **3.1%** |
| **Mean Forecast Lead Time** | **67 minutes** before landfall |
| **Run-up RMSE** | 11.7% |
| **Validation Events** | 23 (1990–2026) |
| **Validation Points** | 712 field run-up measurements |
| **Propagation Range** | 180 km – 14,200 km |
| **Run-up Range** | 0.3 m – 40.5 m |

## 🔬 Seven Hydrodynamic Parameters

TSU-WAVE integrates seven physically independent indicators, each derived from governing equations of long-wave hydrodynamics:

| # | Code | Parameter | Physical Meaning | Critical Threshold |
|---|------|-----------|------------------|--------------------|
| 1 | **WCC** | Wave Front Celerity Coefficient | Normalized wave speed vs. shallow-water celerity √(gd) | > 1.58 |
| 2 | **KPR** | Kinetic-to-Potential Energy Ratio | Depth-integrated energy transfer state | > 2.0 |
| 3 | **HFSI** | Hydrodynamic Front Stability Index | Wave front coherence via h/H₀ ratio | < 0.40 |
| 4 | **BECF** | Bathymetric Energy Concentration Factor | Coastal amplification from bay geometry | > 6.0 |
| 5 | **SDB** | Spectral Dispersion Bandwidth | Frequency-domain energy spread (1–120 min band) | < 1.0 |
| 6 | **SBSP** | Shoreline Boundary Stress Parameter | Wave loading at land–sea interface | > 1.2 |
| 7 | **SMVI** | Sub-Surface Micro-Vorticity Index | Rotational flow at bathymetric discontinuities | > 0.6 |

### Composite Hazard Index (CHI)

$$CHI = \sum_{i=1}^{7} w_i \cdot P_i^{(n)}$$

Where $P_i^{(n)}$ is each normalized parameter and optimized weights are:

```
w₁(WCC)=0.18  w₂(KPR)=0.16  w₃(HFSI)=0.17  w₄(BECF)=0.20
w₅(SDB)=0.11  w₆(SBSP)=0.13  w₇(SMVI)=0.05
```

---

## 🚨 Alert Levels

| CHI Range | Level | Status | Action |
|-----------|-------|--------|--------|
| < 0.35 | 🟢 **MONITOR** | No significant hazard | Passive monitoring |
| 0.35 – 0.54 | 🟡 **WATCH** | Elevated — Advisory issued | Heightened readiness |
| 0.55 – 0.74 | 🟠 **WARNING** | High — Evacuation recommended | Activate protocols |
| ≥ 0.75 | 🔴 **EXTREME** | Imminent — Immediate evacuation | Full emergency response |
