Estimation of Soil Erosion Risk Using ICONA Model: The Case of Ankara

Abstract

When Turkey's erosion risk status and soil loss were evaluated, it was understood that ICONA would be the most ideal model for Turkey among the methods and techniques in the literature. In this study, it was aimed to determine the erosion susceptibility levels of Ankara City, which is stated to have a high risk of erosion due to water, wind and improper land use. For this purpose, ArcGIS 10.7 from geographic information systems software was used and the erosion risk levels of Ankara were determined by ICONA model/method. As a result of the research, spatial erosion risk map as well as erosion risk levels were determined and evaluated. The findings show that the erosion risk is high and very high in approximately 124,300 hectares of land south of Yenimahalle and Keçiören districts, west of Mamak, north of Çankaya and Etimesgut and east of Sincan. This study can serve as an example for future similar studies on determining erosion risk as a single spatial indicator, as well as for the preparation of multi-layered spatial plans and the integrated assessment of different indicators.
