Vulnerability Assessment of Sta.Rosa-Silang Subwatershed using SWAT
Track: Water Resources
Authors: Damasa Macandog
The Silang-Santa Rosa River Subwatershed underwent rapid land use conversion. Digital terrain model (DTM) extracted from LIDAR data, land cover and soil maps, and climatic data were inputted in the Soil and Water Assessment Tool (SWAT) model to simulate water balance. Areas vulnerable to flooding and erosion with low elevation and low permeability were mapped out. Results will be useful in developing mitigation and adaptation strategies to disaster such as landslides and floods.
