Groundwater Analysis Based on the Hydrogeological Model of Taichung Basin, Taiwan
In this study, a hydrogeological model was established and applied for the analysis of flooding potential in Taichung Basin. The groundwater level data from 10 monitoring stations in the past 10 years were used to calibrate the hydrogeological model, before used to predict the groundwater conditions for the extreme scenarios of climate change. The results revealed that Taichung City was influenced by the groundwater recharge effects of Dajia River in the north, the border of Dadu Plateau in the west, Dali River in the south, and the no-flow boundary of Chelungpu Fault in the east. In general, the groundwater level in the Taichung basin was higher in the north and lower in the south. Most areas of the Taichung basin exhibit a seepage coefficient around 0.1 cm/s, however, the areas to the north, near the Dajia River, exhibit a lower seepage coefficient around 0.02 cm/s. The results suggest that the southern part of Taichung basin possess the potential of flooding induced outflow of groundwater. The flooding due to surface flow could be stagnated by the groundwater as well.
