Hillslope soil acts like a water reservoir in the whole processes of water cycle. The cycle of soil water begins with the entry of water into the soil by the process of infiltration, continues with the storage of water in the soil, and ends with it's removal from soil by drainage, evaporation or plant uptake. A permeable soil can reserve great amount of water, reduce surface runoff, and recharge ground water. The results of these processes will reduce peak flow during the rainfall season and increase the baseflow during the dry season. However, the intensive development of the slopeland increases the pavement of soil surface and reduces the soil infiltration capacity which will result in flooding and some time will cause land collapse due to reduction of groundwater refill. The objective of this project is to study the change of hillslope hydrological cycle before and after hillslope development. The soil and hydrological data of slopeland will be collected. The soil water movement in the soil profile will be measured at different time during the developing period. The soil infiltration and storage capacity will be compared before and after land development. Finally, we want to establish a soil water movement model in order to simulate soil water movement before and after development. The results can be used as an index of suitability of slope land development.
