EVOLUTION OF SLOPE SURFACE SHAPE
DURING SEDIMENT SLIDING

Evolution of slope surface shape under sliding: Blue line represents the initial state of slope. Red line corresponds to the moment the sliding process stops.

A layer-by-layer sliding of upper part of elastoplastic sediment layer on slope surface formatted during sliding process is considered.
A picture of successive position of landslide surface for different moments in time, with time step 10 seconds is presented.
Duration of landslide process is ca. 45 seconds. Maximal velocity of movement of landslide fore-front is ca. 6 m per second.
