Management of groundwater in Zhengzhou city, China

Quasi-three-dimensional numerical simulating and optimum management model w as established for evaluating and managing groundwater resources in Zhengzh ou city. Based on the coupling of simulating model with a planning model, a n optimum management model of groundwater resource was established. Through optimum controlling of the groundwater seepage field, environmental proble m caused by unreasonable extraction of groundwater in the study area was de creased to the minimum level, which supply scientific foundation for ground water resource management in Zhengzhou city.
