# Escarpment Retreat Evolution Teaching Dataset

This public dataset contains the precomputed display assets for an educational
web platform about fluvial-erosion-driven escarpment retreat.

## Contents

- 81 MATLAB/TopoToolbox/TTLEM parameter scenarios
- 161 time steps per scenario from 0 to 32 Myr
- Corrected top-down plan views
- Fixed-perspective three-dimensional views
- Basin masks, river-profile data, knickpoints, and scenario metadata

The web release contains 39,368 files (approximately 2.41 GiB).

## Render provenance

- Plan-view JPEGs come only from the final corrected
  `plan-rerender-v3` rendering, with the plateau on the left and basin C
  (yellow) above basin B (blue) and basin A (green).
- Perspective JPEGs come only from the accepted
  `view-rerender-v2` rendering with 5x vertical exaggeration.
- The original high-quality PNG masters are retained offline and are not
  replaced by this web dataset.
- File paths, byte sizes, and SHA-256 checksums are recorded in
  `release/inventory.json`.

## Intended use

The files are published to support the public classroom demonstration at the
Escarpment Evolution Lab website. They are model outputs rather than measured
terrain observations and must not be interpreted as a reconstruction of a
specific real landscape.

## Software and attribution

The simulations were produced in MATLAB using TopoToolbox and TTLEM. Users
should cite the relevant TopoToolbox, TTLEM, and geomorphology literature when
reusing or discussing the model results.

No MATLAB source code, credentials, or private files are included in this
dataset repository.
