Dakeng area is the famous scenic spot in Taichung, the agriculture, the leisure, the ecology, the culture and the tourism are unique to the central part of Taiwan but the development is limited due to the high terrain and the lack of water resources. Therefore it must pump groundwater to provide water supply. Planning how to use groundwater safety yield is the major topic of the study. The present study employs MODFLOW model to simulate groundwater of Dakeng area, and compares with the bole-hole situation. It’s found that the safety yield is 156,639m3/day, and the safety pumping discharge can stand on the simulation result. According to bole-hole data, the MODFLOW can simulate actual geologic distribution that can offer authentic situation, and evaluate the groundwater resource management effectively.
