AB - This study was carried out to estimate the behavior of the debris flow, which was occurred at Umyensan-area in Seoul, Korea in 2011. In this study, we surveyed the topological change by debris flow using terrestrial LiDAR (Light Detection And Ranging) at Umyensan area. For the LiDAR measurement, the terrestrial laser scanning system consists of a highly accurate and fast 3D scanner associated GPS system and high-resolution digital camera were used. The bed slope of the most upstream has the range of 15-25° and kept high slope over 10° until run-off distance of 500m. however the slope decreased to the range of 0-10° at the midstream of debris track. The numerical simulation was performed by using the Finite Differential Element method (FDM) based on the equation for the mass conservation and momentum conservation and erosion/deposition velocity which was proposed by Takahashi. The erosion was increased steeply in high bed slope area within 500m and the deposition was dominant at the downstream of 1,000m. From the comparison with measured data and simulation result, this model was thought to be able to apply to the hazard map
