Abstract

In this study, a basin with an area of 20 km2 was chosen as the study area to more quantitatively understand the temporal and spatial variation of the rainfall-induced sediment volume changes during a period. The 2 m high-resolution DTMs derived from airborne LiDAR data acquired in 2005 and 2010 were used to characterize sediment yield and sediment transport processes such as debris flows and hyper-concentrated flows in the study area. With an acceptable volumetric estimation error (20%) due to uncertainty of the topography, comparing the two temporal DTMs reveal that LiDAR is an efficient way to assess sediment volume changes at the basin scale over a 5 year period.
