A Study On Relationship Between Soil Water And Groundwater

In the case of groundwater balance experimental station data in Xinjiang, using of sod water energy theory, analysis water movement character in unsaturated soil, acquire basic type of water movement in unsaturated soil, study mechanism of soil water recharge groundwater and shallow groundwater evaporation discharge soil water. According to the moisture potential gradient and soil water content in different depth, the author calculate water volume of soil water discharge groundwater by the method of soil water flux. The results show that the method of soil water flux is a simply and available method. According to the principle of water balance, the author built soil water balance formulation. The formulation can calculate water volume of soil water discharge groundwater. The accuracy of soil water balance fonnulation depend on shallow groundwater level, soil water moisture, evaporation, etc.
