摘要：This paper presents the application results of a regional,distributed empirical model: Flow path assessment ofgravitational hazards at a Regional scale: (Flow-R) for a catchment on Woomyeon Mountain, Seoul, Korea. This modelcouples probabilistic and energetic algorithms for assessing of the spreading of flow and maximum runout distance.Flow-R also adopts the Geographic Information Systems (GIS) framework for determining the debris flowsusceptibility for the whole mountain. In this paper,susceptibility scenarios have been simulated taking into accountdifferent source and propagation parameters.The best-fit values for the minimum plan curvature for initiating debrisflow and the travel angle (vertical elevation to horizontal distance ratio) of runout distance were found to be -1/100𝒎−𝟏 and 13°, and the resulting propagation on one of the calibration site was validated using the simplifiedfrictionlimited model.Based on the results, the use ofthis model can be considered an important tool for debris flowanalysis, especially in areas where related properties of the debris flow are not well defined.
