Simulation and Prediction of Groundwater Level at Hatoucaidang Source Field

Numerical simulation of groundwater resources at Hatoucaidang source field was carried out with MODFLOW software.The parameters selected in simulation model were reasonable basically and the model could actually reflect the practical characters of flow field really according to the model identification and verification.Based on the model identification and verification,the initial condition,boundary condition and source collection item were given.The groundwater level was predicted from Oct.2009 to Oct.2029.The results show that the continuous downward tendency of groundwater level of source field will not appear under the designed exploit condition.The groundwater level drawdown predicted by all kinds of schemes is generally small,and the drawdown of most simulation area is mostly less than 6 m,and the whole drawdown is relative small,which will not bring obvious influence to the ecological environment.
