修正版通用土壤流失公式(RUSLE)於 1997 年由 Renard 等學者正式發表，相較於通用土壤流失公式(USLE)，有更全面的思考，各個因子不再是各自獨立，而是互有關聯性且彼此影響的，也因此需將各種資料輸入城市(City Database)；作物(Crop Database)和田間操作(Operation Database)資料庫中，再輸入電腦程式運算。基礎理論依舊承襲 USLE，但大部分的因子利用新的技術去評估，土壤沖蝕指數(K)與覆蓋與管理因子(C)修改為受季節性的氣溫而變化，坡長及坡度因子(L S)可計算紋溝與紋間沖蝕等複雜坡面之土壤流失量。

Revised universal soil loss equation was released in1997 (Renard et al). It was more complete compared to universal soil loss equation. Each factor is correlated rather than independent, and affects each other. Therefore, RUSLE need to input data in city database, crop database and operation database. The basic USLE has been retained, but most factors are evaluated by new techniques and evaluate by new techniques. For example, soil erodibility factor (K) and cover-management factor (C) are varied seasonally by climatic data. The slope length and steepness (LS) can be used in estimate the soil loss ratio of rill erosion and interrill erosion.
