Abstract
The purpose of this study is to establish a management mechanism and to develop strategies of sustainable utilization of groundwater resources. The management framework composes of two major parts, including design of monitoring network and method to identify illegal pumpings. The response matrix technique is combined with Tabu Search algorithm to optimize a monitoring network. The objective of the optimization model is to maximize observable area with fixed number of wells. Furthermore, the study proposes a two-stage procedure named Zoning-Contrast Method for pumping source identification problem. For the study of sustainably utilizing groundwater resources, this study selects Taipei basin as the study area and constructs a groundwater management model based on the response matrix technique. The model evaluates the available groundwater and pumping strategies for different durations of water supply. Moreover, the recovery processes of the aquifer after different pumping strategies are also analyzed. According to the results, the longer duration of water supply, the less daily pumping rate. The recovery of the aquifer displays a slow but steady process. At last, the impact of climate change on groundwater recharge is also evaluated. The change of streamflow due to climate change is further applied as a boundary condition to evaluate the impacts on groundwater recharge. The simulation results indicate that climate change will not significantly influence the groundwater recharge to the major confined aquifer of Taipei basin.
