Modeling and Estimation of Run-of-River Hydropower Potential through Integrated GIS and SWAT Interface in Agusan River Basin

The Philippines, specifically Agusan, is rich in water resources but lacks the reliable information in terms of its potential. Therefore, this study estimates the theoretical ROR hydro potential of Agusan River Basin which passes from Davao de Oro and throughout Agusan del Norte. A 30-m spatial resolution elevation of SRTM-DEM, Climate Forecast System Reanalysis, Global Land Cover Characteristics Database v 2, and Harmonized World Soil Database v 1.2 have been gathered to make the assessment possible using GIS-based spatial tool and SWAT (Soil and Water Assessment Tool) hydrological model Interface. Simulated head drop and flow rate of 111 delineated stream networks were generated considering the meteorological data of 2001 to 2014. The estimated total theoretical run-of-river hydro potential of the basin is 74.49 MW at annual mean flow. Issues like polluting energy sources and pivoting power outages within the territories and provinces of Mindanao can be aided by this hydropower potential associated with geographic and hydrographic modeling.
