蓄水坑灌单坑土壤水分运动模型的有限体积法求解
Numerical Simulation for Single Pit Soil Water Movement of Water Storage Pit Irrigation
摘要
Abstract
Based on the theory of soil water dynamic, a simulating model and boundary conditions for the soil water of water storage single pit irrigation were established, and the model was numerically solved by finite volume method. The results showed that good agreement was obtained between simulated and measured wetting front and soil moisture content. It indicated that the mathematic model was correct and the model solving with finite volume method was feasible. It is concluded that the model could be used to implement water transport in soil under the water storage single pit.关键词
