Study on Numerical Simulation of Groundwater Reservoir Recharge of North Zouping City of Shandong Province

The hydrogeological conditions of northern Zouping city were analyzed, and a numerical model of groundwater reservoir recharge was established in the paper. By the method of quasi-tri-dimension FEM (finite element method) of groundwater unsteady flow, the exploitation of groundwater flow was simulated. The supply capability of groundwater reservoir under the different exploitation scheme are evaluated,and the trendy change of groundwater flow and the scheme of the groundwater reservoir exploitation are predicted. The research results show that diverting Yellow River water to recharge groundwater, decreasing the groundwater exploitation in north area of the city, increasing the groundwater exploitation in dyke net area, the demand of groundwater can be satisfied, the efficiency of the groundwater reservoir and dyke works can be enhanced, the decline of the groundwater table in the east-north area can be prevented.
