Estimating the Soil Erosion Risk Around Ankara-Bağlum Kösrelik Pond Using CORINE Method

Abstract

In this study, the Rural Recreation Area of Kösrelik Pond in the Keçiören district of Ankara was studied. The maps of potential and actual soil erosion risk of about 65 ha of the environment surrounding the pond, which was planned as a rural recreation area, were investigated using CORINE methodology. Accordingly, the necessary physical and chemical soil analyses were performed on 10 surface samples and soil samples from 4 profiles additionally opened on the field, and the maps were created by CORINE methodology using GIS technologies. According to the results of the potential soil erosion risk map obtained in this study, no potential erosion risk was found in 10% whereas, low risk of potential erosion was determined in 9%. In addition medium risk of potential erosion was found in 66%, and high risk of potential erosion was found in 15% of the total area. Nevertheless, according to the results of the actual soil erosion risk map, no actual erosion risk was found in 10% whereas, low risk was found in 2%, medium risk was found in 24%. Moreover, high risk of actual erosion was found in 64% of the total area. It has been observed that the natural vegetation within the study area has substantially prevented erosion. The amount of erosion substantially increases due to the destruction of natural vegetation and soil cultivation of agricultural land
