Abstract

This paper describes a study in which simulated rainfall events, conduced at the field monitoring station in Linghou, Yangling District, Shaanxi, were used to study the effects of various factors (vegetation cover, rainfall intensity, and slope angle) on the soil moisture increase after rainfall and the infiltration recharge coefficient (IRC). Soils hosting 3 different plants (purple medic, PM; spring wheat, SW; and ryegrass, RS) were considered, along with bare soil (BL). These soil surfaces were tested with 4 different slopes and subjected to 5 different rainfall intensities. It is showed that : Vegetation cover yields a greater soil moisture increase than do bare land; Water storage initially grows and then reduces as the rain intensity rise; Water storage increase firstly rises but then falls as the slope grew from 8.8 to 36.4%; IRC rise with growing coverage and falling rain intensity, angle, initial moisture
