Abstract
The southern part of Taiwan caused by heavy rains is facing a serious problem of high water turbidity. Because the uneven spatial and temporal distribution of rainfall and the growth of water resources use in southern Taiwan, water shortage in southern Taiwan region is growing serious.
To solve the problem of water shortage in southern Taiwan, a conjunctive scheme to make some artificial lakes and reservoirs will be applied to establish the amount of groundwater recharge. In this study, a numerical model MODFLOW is adopted to simulate different scenarios in this area.
First, it required pumping test to obtain the hydrogeological parameters of the study area to apply MODFLOW numerical scheme to calibrate, validate and analyze sensitivity of simulation of the four artificial lakes with pumping two different regions.
Hill method is selected to evaluate the safe yields under different scenarios in the study area.The relationship between water depth and groundwater recharge is studied in this thesis.
Last, a Groundwater Management Index is proposed to be a management reference.
