碩士 / 國立成功大學 / 水利及海洋工程學系 / 104 / In Penghu, Taiwan, the quantity of rainfall is less than that of evaporation. There is a shortage of surface water, and thus groundwater is the main water resource. However, the amount of pumping has increased with increasing urban development and population growth, and thus seawater intrusion and groundwater salinization have become more serious.
Previous studies have used a groundwater numerical model to simulate groundwater salinization. Therefore, we use MODFLOW and its sub-mode MT3DMS to simulate the groundwater level and chloride concentration distribution in Penghu. The chloride concentration is used as a salinization indicator. After calibrating and verifying the model, three scenarios are used to predict the groundwater salinization in this area. The results show that a remediation strategy can raise the groundwater level and dilute the salt concentration in whole area. In addition, the priority area for the injection of freshwater is Gangzih village.
