Numerical simulation for evaluating allowed water exploitation from deep aquifer in Zhaoyoufang

Hydrological parameters of groundwater resources zone in Zhaoyoufang are attained by pump experi-ment.The mean conductivity coefficient,elastic storage coefficient,pressure conductivity coefficient,hydraulic jump value are 878.27 m²/d,6.85×10^-4,1.55×10⁶ m²/d,3.44 m,respectively.Based on those parameters,the groundwater resources zone is divided into 6 units.Selecting the proper model to simulate groundwater level change under different exploitation condition,it shows that No.1 exploiting 24 000 m³/d design is more reasonable.
