Prediction and Optimization of Groundwater Development in Beijing Plain

Article Preview

Abstract:

Groundwater plays an important role and accounts for two-thirds of the total water supply in Beijing plain. Overexploitation of groundwater has caused continuous decline in groundwater levels, land subsidence and other environmental and ecological problems. To analyze current status and predict future trends in groundwater resources, a 3D transient groundwater flow model was established and used to simulate various groundwater resources development schemes. With considering some facters such as groundwater exploitation, river outflow, groundwater levels and so on, an evaluation index system was constructed. Based on this index system a multi-object decision model was established for estimation of groundwater development schemes and proven to be very useful for scientific analysis of reasonable development and utilization of groundwater resources.
