Comparison of soil erodibility of different segments of a slope in semiarid climate condi̇tions

This study was carried out in the Tekneli Village in Uğrak Basin which is 16 km away from Tokat city center. In this study, possible variations in the soil erodibility factors values of five different parts of a complex slope were investigated. Five parts of the complex slope were determined as summit, shoulder, back-slope, foot-slope and toe-slope. A total of 25 top soil samples were collected from each section of complex slope. Organic matter, texture, very fine sand, hydraulic conductivity, structure type and size were determined and K factor values were calculated. There was no statistically significant difference between soil erodibility factor values of different parts of the slope. Along the slope, the soil erodibility values of soils was very low and showed a low risk of water erosion.
