Abstract
Population growth encourages changes in land, and results in increased settlement land. This can have an impact on the hydrological process in a watershed. With land changes along with domestic, agricultural and industrial activities, settlements will have an impact on river water quality. Pollutants originating from runoff water of various types of land use including settlements and industry and the results of this human activity are called non point source pollutants (NPS). A tool or tool is needed that can estimate the NPS pollutants produced in a watershed. Tools that can estimate Non Point Source pollutants are using the BASINS application. BASINS is designed to conduct watershed-based research and water quality. BASINS integrates data in an environmental Geographic Information System (GIS). The BASINS has a variety of models, one of which is the Pollutant Loading Estimator (PLOAD), which is a simplified GIS-based model for calculating pollution loads for watersheds.
