Abstract:

In this study, thematic maps of Madgao and Saug Rivers Watershed in Asuncion, Davao del Norte, Philippines were generated through Quantum Geographic Information System (QGIS) software in order to estimate surface runoff as basis for sediment load simulation with the aid of Hydrologic Engineering Center – River Analysis System (HECRAS) software. As a quantitative-descriptive-evaluative study, the primary data gathered from the Philippine Atmospheric Geophysical and Astronomical Services Administration (PAGASA), National Irrigation Administration (NIA) and Provincial and Municipal Planning and Development Offices (PPDO & MPDO) of Davao del Norte and Compostela Valley and the secondary data from engineering surveys enabled the researchers to provide numerical and narrative description about the characteristics of the study watershed and the behaviour of the riverine system. This study will be helpful in monitoring watershed health, the functionality of Saug irrigation facility and in mitigating existing or possible sedimentation risks. It benefits the national and local governments, the entire community within Madgao and Saug Rivers Watershed, engineers, Department of Environment and Natural Resources (DENR), the future investigators and researchers.
