Abstract: Groundwater in the region of middle and lower reach of Daguhe River Basin is one of the main water supply sources for the Qingdao City. However, due to excessive and non-planned withdrawal of groundwater, serious environmental impacts arise, such as groundwater contamination, land subsidence and seawater intrusion, etc. Therefore, an appropriate groundwater management is imperative in the region and Daguhe Groundwater Reservoir Project is carried out. This paper analyzes the water conditions of the groundwater reservoir and uses the two-dimensional mathematical model to simulate the groundwater flow field. Finite difference method is applied for the solution of the model and parameters are determined by the typical year recorded values. This paper also provides a parameter calculation process, which is to improve the groundwater flow model. Programme of this model is used as a modular of the fundamental model of Qingdao water resources macro-management.
