Abstract: Located along the typhoon belt in the Pacific, Philippines is visited annually by an average of 20 typhoons. This brought frequent flooding to communities and caused damage to flood prone residents. This study is aimed to generate GIS flood model to simulate flood inundation using Synthetic Aperture Radar (SAR) data and Digital Terrain Model (DTM) derived from Light Detection and Ranging (LiDAR) datasets. Open-sourced HEC-HMS and HEC-RAS Models were used. HEC-GeoRAS in ArcMap was used to preprocess geospatial data of Padada River basin in the Southern Philippines. The result of the study has identified inundated areas and communities for a 24-hour 5, 25, and 100- year return periods as well as flooded critical facilities in the flood plains. The output of this study can be used in planning and predicting flood risks for mitigation.
