Infiltrating Test on Artificial Simulated Torrential Rain in Shanghai Vegetable Area

According to the principle of water amount balance, the infiltrating tests of artificial simulated precipitation in various precipitation intensity and soil humidity conditions are made in Shanghai old and new vegetable areas, and the dynamic experimental data in infiltrating process of torrential rain and fundamental parameters and law of infiltration are obtained, and the law of soil moisture variation is analysed, which could be used as the foundation of the evaluation for torrential rain disaster.
