Abstract

The study assessed the impacts of land-use change on runoff in the Manikin Basin, using the Soil and Water Assessment Tool (SWAT) model. The model use to predict runoff for two scenarios. Both scenarios using different land-use data. Land-use for the SWAT model is obtained from remote sensing images. Two remote sensing images of Landsat 8 OLI from the years of 2014 and 2019 were used for land-use classification using the supervised classification method. The classification results show that there is a change in land-use. Area of land-use with the highest increase was shrubs with an increase of 20.25% (19.98 km 2), while the land-use area with the highest decrease was forest with a decrease of 14.1% (13.92 km 2). The average annual runoff of the first scenario is 134.7404, while the average annual runoff of the second scenario is 140.0596 mm, there is an increase of 3.98% (5.19 mm). This study shows that, the increase in the area of shrubs, and the reduction in forest area have an impact on increasing surface runoff in the Manikin watershed
