中文摘要

Sediment yielded from a watershed is usually generated from various sources. Nowadays numerical models at different spatial scales are available to estimate soil loss from a watershed. Nevertheless sediment yield from slump or landslide still depends on empirical relationships to estimate the likely sediment production that often calculated landslide depth. Total of 108 landslide sites acquired from three watersheds situated in southeast corner of slate and shale geological formation of Taiwan, with the drainage areas of 102.65, 102.46 and 145.16 km2, respectively, constitutes the field data domain. The results of this study indicate landslide depth is poorly correlated with average slope of the landslide extent. It is better correlated with the projected area of the landslide extent. A regression equation is generated that provides acceptable landslide depth estimation for the projected area of landslide extent up to 1 km2.
