AB: The annual average precipitation of Taiwan is 2515 mm, which is 2.6 times of the world annual average precipitation. However, due to steep topography of the island, only 15 percent of the total precipitation is available for the use of water resources. The recent climate change makes the situation even worse. To evaluate the impact of climate change on groundwater resources management, Ping-Tung Plain was taken as a research area. A conceptual hydrogeological model based on lithology, geophysics and geochemistry was constructed. Numerical modeling using Modflow-Surfact is conducted to investigate the impact on water resource due to the climate change in the southern Taiwan. The results show that under the condition of climate change the groundwater level in the mountain area of ping-Tung Plain will be affected most serious. Since the mountain area is the most important recharge area of Ping-Tung Plain, the lowering water level may show an alarm for the decrease of available groundwater of this area in the future.
