ABSTRACT

In mountainous areas in Korea, there is increasing damage caused by landslide disasters due to the effects of typhoons and heavy rainfall in summer, and there is an increase in the frequency not only in the forest but also in mountainous areas adjacent to downtown. In particular, because there has recently been a rapid increase in life and property damage caused by debris flow, the prevention and responses are required from the perspective of disaster prevention. Therefore, this study generated a high-resolution DEM and calculated the sediment yield using the measured data by terrestrial LiDAR for establishing topographic data in the areas affected by debris flow. It also understood the movement characteristics of the debris flow and calculated the extent of damage by applying the RAMMS model, a numerical analysis model, to the areas affected by debris flow. As a result, the extend of debris flow calculated by the RAMMS model was similarly simulated in the longitudinal and transverse directions in comparison with the actual measured data on the affected areas.
