Abstract

Soil erosion is an environmental problem in the tropics that can cause the loss of topsoil. If it continues, it will result in a decrease in soil fertility and land productivity. So, it is necessary to quickly predict the erosion hazard level using the USLE method based on GIS. This research aims to analyze the distribution of erosion hazard levels in the Durensewu Sub-watershed, Gadjah Mungkur Reservoir Wonogiri, based on GIS. The research was conducted in the Durensewu Sub-watershed, Wonogiri, in January-April 2024. Data processed include rainfall (R), erodibility (K), slope (LS), and land cover and management (CP). The R-value in the Durensewu Subwatershed is 169.24-204.216. Soil groups of Ustropepts and Dystrudepts showed K values of 0.39 and 0.46, respectively. The topography of the Durensewu Subwatershed is gently sloping to very steep. Mixed gardens, settlements, and rice fields dominate land use. The erosion hazard level in the Durensewu Subwatershed is evenly distributed in the mild, moderate, and severe hazard classes.
