Abstract

Landslide erosion and sediment delivery to the Shihmen Reservoir watershed in Taiwan was estimated using empirical landslide frequency–area and volume-area relationships, empirical landslide runout models, and the Hydrological Simulation Program- FORTRAN (HSPF). Landslide erosion rates were evaluated during the period 1986-2004. They increased following Typhoon Aere in 2004. The percentage of landslide sediment delivered to streams decreased from 78% during the period 1986-1997 to 55% in 2004. Model simulations indicate that only a small proportion of the landslide material was delivered downstream. In general, the transfer of sediment in the fluvial system in the Shihmen Reservoir watershed is dominantly transport limited. The imbalance between sediment supply and transport capacity has resulted in a considerable quantity of landslide material remaining in the upper-stream regions of the watershed
