GROUNDWATER MODELING AND MANAGEMENT OF A COATAL AQUIFER IN EASTERN CHINA
This study presents the establishment of sustainable development and management policies for the Dagu River aquifer system in eastern China. Geological, hydrogeological data are used conjunctively to define various hydrogeological units and their geometry. Distributions of hydraulic parameter values and recharge are estimated by geostatistical methods and hydrologic simulations, respectively. A quasi-three-dimensional groundwater flow model is built to represent the unconfined flow in the aquifer system through finite-difference method. The model has been calibrated and verified under transient conditions. The resulting model was used to test five management scenarios to determine sustainable yield of the aquifer system and to investigate the potential impacts of five rubber dams on groundwater resources in this watershed. The results demonstrate that the regulation capacity of the aquifer can greatly be enhanced and form a long-term water supply potential with rational arrangement of artificial recharge and supplemental recharge of rubber dams. This study is beneficial for management of the coastal aquifer and water resources sustainability in water shortage areas of the eastern China.
