Özet: The aim of the study is to determine the amount of water-related soil loss in the Bakırçay Basin which is located west part of Anatolia and to evaluate the relation between the current land use / cover and the erosion risk situation. In this paper the soil loss model Revised Universal Soil Loss Equation-RUSLE was used to quantify soil loss in the basin. Soil samples obtained from the 108 field plot has been determined according to the gird method and analyzed in the laboratory, digital elevation model for LS factor and precipitation data were analyzed with Geographic Information System GIS techniques. LANDSAT Operational Land Imager OLI satellite image with a spatial resolution of 30m of July 2013 was used to determine existing land use / land cover situation of the study area. According to the results of the research, it is found that the amount of soil loss due to water in the Bakırçay Basin has reached the highest values on the mountainous masses surrounding the basin floor, which has high slope values and high deforestation. In addition, the risk of erosion in areas where mining activities carried around Soma has been found to be very high. Depending on the continuation of the change in the land due to the mining and agricultural activities, it is possible that the risk of soil loss increases. In this context, the risk of soil loss should be taken into account, especially in watershed planning and management studies, and decision makers should consider this situation
