Application of Groundwater Model to Groundwater Regulation in Cangzhou Area

Abstract

The development and utilization of groundwater in Cangzhou area has led to a series of environmental and geological problems such as groundwater-level declines and land subsidence. In order to alleviate the impact of groundwater abstraction on geological environment, a calibrated, transient groundwater numerical model of the Cangzhou area was developed using Processing Modflow. Then four kinds of groundwater exploitation schemes were designed and the groundwater flow fields for different schemes in the next 50 years were simulated and predicted. By comparing and analyzing the variation of the water levels in the mining layers and the variation of groundwater storage, the optimal groundwater extraction scheme was determined.
