RIO

SIH Problem — Generalized Framework for Dam-Break & Flood Analysis

A scientific computing platform for dam-break analysis, river blockage analysis, flash-flood scenario generation, and flood inundation simulation. Designed for Humanitarian Assistance and Disaster Relief (HADR) decision support, integrating SPH and Delft3D hydraulic models with GIS visualization, satellite data, and automated impact analysis.

Important: Current Status

All SPH and Delft3D outputs in this platform are MOCK/DEMONSTRATION ONLY. The real DualSPHysics and Delft3D-FLOW solvers have not been installed. The model adapters are complete and ready — only the solver executables need to be provided. Synthetic DEM, hydrology, and infrastructure data are used. Results must not be used for any real emergency or engineering decisions.

The Smart India Hackathon (SIH) problem addressed by this platform is the development of a generalized software framework for dam-break analysis, river blockage analysis, flash-flood scenario generation, and flood inundation simulation.

•Dam-break analysis (parametric breach models)

•River blockage / landslide dam analysis

•Natural lake / glacial lake outburst (GLOF) analysis

•Flash-flood scenario generation

•Flood inundation simulation (depth, velocity, arrival time)

•Hydrological data processing

•DEM processing (slope, hillshade, flow direction)

•Satellite data integration (Sentinel-1/2, Landsat)

•Loss, damage and impact analysis

•Model comparison (SPH vs Delft3D)

•GIS visualization and export (SHP/KML/GeoJSON/GeoTIFF)

•Near-real-time flood analysis

•HADR decision support

RIO — SIH Project

Built with Next.js, FastAPI, MapLibre GL JS, NumPy, and open-source GIS libraries.

All simulation outputs are MOCK/DEMONSTRATION DATA. Not for real emergency use.
