Potential Impacts of Land Use Changes on Water Resources in a Tropical Headwater Catchment

The main objective of this study was to investigate the relationships between land use and future scenarios of land changes on water runoff and groundwater storage in an Environmental Protection Area (EPAs) watershed. The methodology was based on the application of the Soil and Water Assessment Tool...
