A Proposed Calculation Method for Land Subsidence Caused by Groundwater Withdrawal in Jiangsu Province
This paper proposed a coupled calculation model for land subsidence caused by groundwater exploitation, which can consider the variation of permeability of the confining aquifer during pumping. The coefficient of permeability of the confining aquifer can be calculated using water head decline. Coupling with the linear relation of water level decline and land subsidence, the subsidence is easy to compute. A case of Qingliang Primary School in Jiangsu province is conducted to verify the effectiveness, and the results indicated that the coupled calculation model could agree well with the measured data. Based on the coupled model, the water level decline and land subsidence can be predicted, which is important for making the groundwater exploitation plans.
