Management of groundwater in Zhengzhou City, China

Quasi-three-dimensional numerical simulating and optimum management model was established for evaluating and managing groundwater resources in Zhengzhou city. Based on the coupling of simulating model with a planning model, an optimum management model of groundwater resource was established. Through optimum controlling of the groundwater seepage field, environmental problem caused by unreasonable extraction of groundwater in the study area was decreased to the minimum level, which supply scientific foundation for groundwater resource management in Zhengzhou city.
