Abstract :
This research aims to estimate the amount of sedimentation and determine the spatial distribution of sedimentation. The research was carried out in the Paguyaman sub-watershed using the Soil Water Assessment Tool (SWAT) analysis. It was carried out with the help of a Geographic Information System (GIS) with ArcGIS 10.4 software through the process of delineation, formation of a Hydrological Response Unit (HRU) Using land use input data, soil type , slope. The results indicate that the Paguyaman sub-watershed has 8202 HRU's and 475 sub-basins, of which there are 5 classifications of sedimentation quantities, namely very high sedimentation 285.26 ha with a percentage of 0.26%, high 87.78 with a percentage of 0.08%, moderate 505.94 with a percentage of 0.46% , low 3040.37 ha with a percentage of 2.79% and very low 105171.27 with a percentage of 96.41%.
