摘要
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。
Based on the moving mean slope (MMS) model developed by Moldrup et al.(1989) for simulating water movement in unsaturated soils, the flow of moisture undel ponded infiltration in several soils, was computed. The results indicated that the MMS model was a convenient and fast tool for easy and accurate modeling of one-dimensional flow of water in unsaturated soils,especially in simulating water movement in clay soils.
