Simulation and Prediction of Groundwater Flow in Jingan Water Source Area

The groundwater numerical simulation is one of the major methods for evaluation of groundwater resources. the groundwater numerical model of Jingan water source area is established by using GMS,and simulate different mining schemes designed with the model,forecasting the groundwater flow field and water level of various schemes in 20 years under the precipitation guarantee rate 95 %. The results show that when the total exploitation quantity of water source area is 100 000 m3/d,the groundwater flow field can reach a steady state,and the center water level drawdown is relative small,and which will not bring obvious influence on the ecological environment.
