Study on Infiltration of Soil in Action of Soil and Water Conservation Measures and Surface Runoff Yield in One Storm

Based on infiltration capacity curve, the paper demonstrates the amelioration of soil infiltration capability under the soil and water conservation measures from theoretical and experimental analysis. Considering that the infiltration capacity curve can't express the actual infiltration capacity, the authors develop the surface runoff yield models that combine with the infiltration capacity curve, unstable raining process and antecedent soil moisture in each rainfall or over a duration time.
