Due to the increased importance of soil degradation investigation in the Libyan Mediterranean region, soil erodibility-related data is extremely needed. In the present study interrill soil erodibility (Ki) and interrill detachment rate (Di) were estimated using WEPP-formulae. In order to apply the formula, soil properties such as soil texture parameters, organic matter content, exchangeable calcium and saturated hydraulic conductivity (Ks) were measured. The calculated values of erodibility (Ki) ranged between 2.25 x 105 to 5.39 x 105 kg.s.m-4. Multiple regression analysis showed that soil texture parameters, Ks and exchangeable Ca+2 explained about 92% of the interrill detachment rate. The slope factor also played an important role in the soil detachment process. The comparison between the used WEPP-Ki and the soil instability indicators showed that WEPP-Ki equation need to be reconsidered and should include more factors that affect soil structure stability under the Libyan Mediterranean conditions.
