Erodability (or erodibility) is the inherent yielding or nonresistance of soils and rocks to erosion. A high erodability implies that the same amount of work exerted by the erosion processes leads to a larger removal of material. Because the mechanics behind erosion depend upon the competence and coherence of the material, erodability is treated in different ways depending on the type of surface that eroded. ==Soils== The most commonly used model for predicting soil loss from water erosion is the ''Universal Soil Loss Equation (USLE)'' (also known as the K-factor technique), which estimates the average annual soil loss as: : where ''R'' is the (rainfall erosivity factor ), ''K'' is the soil erodibility〔(Soil Erodability (K-Factor) in Europe, European Commission. )〕〔Panagos, P., Meusburger, K., Ballabio, C., Borrelli, P., Alewell, C. Soil erodibility in Europe: A high-resolution dataset based on LUCAS, Science of Total Environment, 479–480 (2014) pp. 189–200 (Open Access): 10.1016/j.scitotenv.2014.02.010〕 , ''L'' and ''S'' are topographic factors representing length and slope, and ''C'' and ''P'' are cropping management factors. Other factors such as the stone content (referred as ''stoniness''), which acts as protection against soil erosion, are very significant in Mediterranean countries. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Erodability」の詳細全文を読む スポンサード リンク
