Abstract: Flooding is a natural disaster that can ruin natural resources, cause casualties, and harm the environment. Floods are known for their deadly and destructive impacts. To predict important information about flooding, such as the extent of inundation and water surface elevations at specific locations, hydraulic modeling and Flood Inundation Mapping (FIM) must be used. A crucial tool for flood monitoring is the HEC-RAS software and remote sensing (RS) technology, in combination with geographic information systems (GIS). The primary emphasis in this discipline revolves around the definition of flood zones and the preparation of flood hazard maps for at-risk regions. This map could allocate land development priorities, and prepare services for future emergency aid and relief interventions in at-risk locations.

Keywords: flood hazard, HEC-RAS, hydrological models, geospatial data, GIS
