Climate change and land use dynamics have created an imbalance in the hydrometeorological cycle, increasing abnormal precipitation and extreme events like flooding. This study uses HEC-RAS model, along with ArcGIS extensions HEC-GeoRAS, HEC GeoHMS, and ArcHydro tools to estimate the inundation in the Pamba River Basin, Kerala. The simulation results for various discharge scenarios are visualized through a web application, enabling a better understanding of the impact of the hazard on the Pamba River Basin.
