Abstract: Firstly the necessity of water erosion modeling on hillslopes is discussed. Then existing water erosion models are generally divided into two types, formalization logic computational models and dialectical logic computational models(according to the way of solving problems)where the former can be further divided into four types--primarily empirically based, partially conceptually and partially empirically based, partially process based and partially empirically based, as well as theoretically based as weak points of the previous classification methods are concerned. Finally characteristics of each type and their relationships are illust rated by examples.

Key words: water erosion modeling on hillslopes, formalization logic computational models, dialectical logic computational models
