Abstract
The amount and intensity of precipitation have long been considered to be two of the main factors that trigger landslides, so rainfall duration and intensity are used in virtually all landslide-warning systems. The effect of
the infiltration of water and the increase in the pore water pressure in slopes are usually neglected in traditional approaches.
This study demonstrates the effect of water storage content in a slope by using the correlation between the transient water storage index and the real time surface displacement. A tank model is used to model the water storage content and four deep-seated creeping landslides in the TienChih area, which recorded continuously using GPS, are studied as examples. The result demonstrates that the soil water index correlates more closely in time to the landslide motion than the rainfall intensity.
Key Words: Tank model, GPS, WSI (water storage index), correlation function.
