Abstract

Global warming causes significant climate change throughout the world. Taiwan is located in the western Pacific typhoon path and cannot avoid the influence of climate change. In response to the change of rainfall patterns affecting the stability of highway slopes in southwestern Taiwan's mountainous areas, the highway slope, which is located in Nan-hua Reservoir catchment, is the research subject for this study. Typical slopes in the mountainous areas of southern Taiwan consist of the colluvium at the shallow depth. The data of borehole drilling is used to understand the stratum distribution underground as well as setting incline monitoring and a piezometer. In addition, a rain gauge is used to obtain local rainfall data. According to the study results, the relationship between the rate of groundwater change and the duration time is expressed as an exponential function. Besides, the relationship between the groundwater change rate and the accumulated rainfall is established in this study. Hence, by monitoring the rainfall we can predict the variation in the amount of groundwater and the groundwater rising rate, enabling us to determine whether or not the groundwater is close to the highest elevation.
