Analysis of Water Cycle in Weizhou Island of Beihai City, Guangxi Province, Part I: Theory and Model Parameter Identification
Abstract
Groundwater is almost the unique source of water for Weizhou Island. Groundwater overexploitation has caused the groundwater level gradually dropping these years, causing many environmental problems such as seawater intrusion. On the basis of previous water resources survey and the understanding of the water cycle of Weizhou Island, the precipitation-runoff and variable-density groundwater flow analysis model in Weizhou Island was established. Model parameters were identified by historical rainfall and groundwater level data.
