Effects of Slope Shapes on Soil Erosion

Water is one of the most important erosive forces. A great number of factors also play a role in erosion processand slope characteristic is also one of them. The steepness and length of the slope are important factors forrunoff and soil erosion. Another slope factor that has an effect on erosion is the shape of the slope. Generally,different erosion and runoff characteristics exist in different slopes which can be classified as uniform, concave,convex and complex shape. In this study, the effects of slope shape on erosion are stated and emphasized bytaking similar researches into consideration.
