Numerical simulation of the groundwater at sedimentary field in the Liudaogou Catchment on the northern Loess Plateau, China
In the Chinese Loess Plateau,construction of a check dam at downstream in a gully has been verified as an effective measure to mitigate the loss of soil and water.The alluvial plain generally has been formed due to sedimentation at the upstream-side of the check dam after 20 or 30 years since its construction.Combination of the check dam and the sedimentary field impacts on water flow in each small dam basin significantly.The shallow groundwater(phreatic water)has come into being at the sedimentary field.In the current study,field survey and hydrological observations were conducted at a sedimentary field of the Liudaogou Catchment.A numerical model for shallow groundwater calculation was developed based on kinematic wave theory and its validity was tested and verified by numerical simulation of the observed groundwater level.Result of the current study is expected to provide the basis for further studies on groundwater at the sedimentary field on the northern Loess Plateau.
