根据Moldrup等提出的运动平均斜率（movingmeanslope）模型，对重粘土、轻粘土、粉质粘土和壤土及前3种粘性土壤所构成的层状介质中的水分，在入渗条件下的运动进行了数值模拟。结果表明，这种新模型对粘性土壤水分动态的预报较传统有限差分数值模型简捷、快速。
According to the moving average slope model proposed by Moldrup et al., The movement of water in the layered media composed of heavy clay, light clay, silty clay and loam and the first three kinds of clay soils under infiltration conditions Numerical Simulation. The results show that the new model can predict the water dynamic of cohesive soil more quickly and easily than the traditional finite difference numerical model.
