| Abstract: | The high mineralized water of Xiaochi and Yanhu, recharging inversely into aquifer caused by groundwater extraction, is a big aquatic environmental problem in Yunchen city. According to very complex conditions on hydrogeology of research area, a quasi three dimensional numerical model, which describes the leaky system of unsteady flow with nonhomogeneous five-layer structure, is presented in the paper. This model lays special stress on considering the three main points: (1) hysteresis effect of rainfall infiltration; (2)groundwater release or storage from aquitard by water head rising or falling; (3)evap-ortranspiration intensity varied with the depth of water table, lithology of aeration and plants. The non linear complex mathematical model is solved by the numerical method of finite element. Based on the model, three selected schemes are run on the computer. Salinization tendency of groundwater is predicated and evaluated at Yunchen city in the future ten years from 1990 to 1999. |
