The Optimization of Groundwater Exploitation Scheme in a Certain Water Intake Project of Heilongjiang Province Using Numerical Simulation Based on GMS

Based on the local hydrogeological conditions,the numerical simulation of groundwater flow field in a certain water intake project of Heilongjiang Province was carried out.Under different exploitation scenarios the model predicts the trend of regional water level changes.The results show that under the same exploitation quantity,the second scheme is the better one to reduce the evaporation discharge and increase the river recharge in a reasonable way by optimizing the locations of pumping wells,which can not only ensure water supply quantity but also reduce negative influence on groundwater environment by the water intake project exploitation.
