Assessment of sediment delivery from successive erosion on stream-coupled hillslopes via a time series of topographic surveys in the central high mountain range of Taiwan

Mass wasting may only affect part of the total failure's area. Volumes of eroded sediment from gullies on the landslide scar may be as high as the volume estimated for the initial failure. The geometry of the sliding masses eroded after the initial failure appears to be uniform, and their depths average 6.1 ± 2.2 m.
