Development of a 3-D numerical groundwater flow model of the Pinggu Basin and groundwater resources management

As the capital of China,the city of Beijing faces a serious threat of groundwater over-exploitation.In order to lighten the contradiction between water demand and water supply,two emergence wellfields were constructed in the Pinggu basin located in the eastern Beijing.Continual over-exploitation of groundwater led to a sharp decline in water levels in the basin,especially near the wellfields.The main intent of this study is the development of a 3-D transient groundwater flow for analyzing the wa...
