VBasin
Builds a basin model from a DEM, with the derived stream network reconciled to the real river, reads the VRain design-rainfall package and computes design flood hydrographs with HEC-HMS; exports boundary conditions for HEC-RAS and VFlood.

Explore model results on a map, hour by hour, with flood depth, extent and arrival time; click any point for its hydrograph. Starts with the Tamiang flood during Cyclone Senyar (2025).

A map viewer for the lab’s flood simulations. Play the flood through time, switch between depth, maximum extent and time of peak, compare with satellite-mapped flooding, and click anywhere for the depth hydrograph at that point. Each simulation lists its model, inputs and limits.

Rainfall–runoff–inundation flood model in Python (NumPy/Numba). Simulates how rain becomes river flow and overland flooding across a basin; it produced the lab's flood simulations.
