A large number of sand cause the reservoir to deposited and because the water muddied, there is no water to use for ten more days in Taoyuan. In order to understand the reason of the landslide, we compare with the landslide data included the years of 1986, 1998, 2003, 2004, 2005 and the factors of geology, slope, direction of the slope, land-used, river, road, village, rainfall in relationship. The reason of landslide in the Shihmen reservoir watershed was because of the geology condition and cumulative precipitation.
