用人工降雨和数值模拟方法研究降雨入渗规律

Study on soil infiltration law with artificial rainfalland numerical simulation

进行四种雨强处理的人工降雨土壤入渗田间试验，并对入渗过程进行数值模拟，提出初始土壤含水率分布均匀时降雨～入渗～径流过程的简便计算方法．

The field experiments of soil infiltration are conducted under the condition of four treatments with different rain intensity.The numerical simulation are carried out in the process of filtration and a simple computational method is given to analyze the course of rainfall,infiltration and runoff.
