Abstract

The experiments, using medium-grained silica sand in a rectangular flume, consisted of detailed observations of failure process consisting series of failures successively, with particular emphasis on the time of failure; shape, size and position of the slip surface; and final shape of the model slope after down-slope displacement of the failure masses. Moisture profiles at different points within the model slope soil domain and the profile of surface-water forefront were also reported. It is highlighted that initial failure is not always necessary from the region near the toe of the slope. This study also noticed a strong correlation between rainfall intensity, sliding initiation time, and sliding head. Failure initiating near the toe propagates an unstable zone toward up-slope. Failure initiating toward the head reach may propagate down-slope and then up-slope
