Core Capabilities

Powerful tools for 2D hydraulic analysis and visualization

2D Saint-Venant Equations

Full shallow-water equation solver handling complex flood dynamics, supercritical and subcritical flow transitions with high numerical stability.

🗺️

Mesh & Terrain Visualization

Adaptive computational mesh generation over real-world terrain data. Visualize DEM-based bathymetry and overland flow paths interactively.

🌊

Flood Inundation Modeling

Accurate floodplain delineation for storm events, dam breach scenarios, and sea-level rise projections — visualized frame by frame.

About This Project

RAS Web Animations is an open demo platform showcasing HEC-RAS 2D hydraulic model outputs as interactive, high-quality web animations. Built with vanilla JavaScript and anime.js, every visualization prioritizes both scientific accuracy and visual clarity.

Whether you're an engineer validating a floodplain study or a student learning hydraulic principles, these animations translate complex numerical results into intuitive motion.
