摘要

通过对假设灌溉沟的模拟,使用数值模型分析了泥沙输移和水流深度对土壤水分剖面的影响。采用基于有限差分法的MacCormack格式求解Saint-Venant和泥沙连续性方程,分析陆上水流和泥沙输移,采用Richards方程分析地下水流,采用质量守恒全隐式有限差分方法求解。水流深度显著影响灌溉渠道中的水分剖面,而泥沙对水分剖面的影响不显著。利用该模型研究了入渗对灌溉沟水分剖面和土壤保水曲线的影响。结果表明,入渗显著影响和改变了土壤水分剖面和土壤保水曲线。在不同的土壤参数(av和nv)和饱和导水率()中,与其他保持参数相比,显著影响水分剖面,而影响土壤保水曲线(SWRC)。

Effect of sediment transport, flow depth and infiltration on soil moisture profiles in irrigation furrows
A numerical model was used to analyze the effect of sediment transport and flow depth on soil moisture profiles from a simulation of the hypothetical irrigation furrows. The Saint Venant and sediment continuity equations were solved by using MacCormack scheme based on finite difference method to analyze the overland flow and sediment transport, and Richards equation was used to analyze the subsurface flow, which was solved by using a mass conservative fully implicit finite difference method. Flow depth significantly affected the moisture profiles in irrigation channels while the effect of sediment-laden water on the moisture profiles was observed insignificant. The model was used to study the effect of infiltration on moisture profiles and soil water retention curve (SWRCs) in irrigation furrows. It was observed that infiltration significantly affected and altered the moisture profiles and soil water retention curve (SWRC). Among the different soil parameters (av and nv ) and saturated hydraulic conductivity ( ) significantly affected the moisture profiles, while and influenced the soil water retention curve (SWRC) as compared to other retention parameters.
