Numerical Simulation on Homogeneous Soil Moisture Movement in Single Water Storage Pit

本文从土壤水动力学的基本理论出发 ,建立了蓄水坑灌条件下的二维剖面土壤水分运动数学模型 ,并采用ADI法结合Gauess-Seidel迭代法进行了数值模拟。验证实验表明 。

According to the fundamental theory of dynamics of soil water , the numerical model of soil water movement in 2-D section was established under the condition of water storage pit irrigating. ADI method and Gauess-Seidel iterative method were used in numerical simulation .A series of experiments were conducted to verify the model. It indicates that the calculated results were in accordance with the experimental results.
