HEC-GeoRAS

HEC-GeoRAS is a specialized software extension for ArcGIS that helps analyze and visualize flood risks. It integrates geographic data (like land elevation and river paths) to simulate how floodwaters might spread across areas, based on different flow scenarios. By processing this information, planners and engineers can identify vulnerable locations, design flood defenses, and make informed decisions to protect communities. Essentially, HEC-GeoRAS translates complex flood models into visual maps, providing a clear understanding of flood hazards and aiding in effective flood risk management.
