Water caused by soil erosion is one of Turkey's most important problems. Especially when people do unconsciously every day activities due to these problems is increasing. This study also located on the shores of the Gulf of Edremit Zeytinli Creek basin and the total annual soil erosion risk area and map aimed to determine the amount of loss. GIS-based RUSLE under this goal (3D) method is used. Model during the implementation of Geographic Information Systems (GIS) and Remote Sensing (RS) methods and software are employed. As a result, low, slight, moderate, high and severe erosion risk to the five different classes of watershed area was determined and the amount of total annual soil loss was estimated to be around. Accordingly, 56.01% of the basin of the severity of erosion risk was highest, 43.99% is not more than the degree of risk. The total annual amount of soil loss in watershed area at approximately 14.23 tons. The slopes for erosion in the basin as a result of the high, or destruction of ground cover were weak, thin character of the valley density and soil properties is more severe in areas that have been seen. The field of erosion for the prevention of natural vegetation, conservation, open space and trees to continuous forest and meadow areas of creation, erosion monitoring and prevention system should be established and people informed about this subject is needed.
