Abstract
Increases in ground water pressure due to rainfall or thawing are known to give occasion to landslide movement in many cases. However, time series behavior of ground water pressure has not been considered in the studies which aim at quantitatively analysis of landslide movement. The present paper deals with the statistical confirmation of the effect of ground water level as against landslide movement and thus presents a simple landslide model, to lead to a long-term determination of landslide movement due to ground water level fluctuation.
