EVALUATION METHOD OF OCCURRENCE RISK OF DEBRIS FLOW, AND EVALUATION PROGRAM OF OCCURRENCE RISK OF DEBRIS FLOW
To provide an evaluation method of occurrence risk of debris flow suitable for railroad vehicle operation regulations.SOLUTION: The evaluation method of occurrence risk of debris flow includes the steps of: calculating the limit surface flow rate for each multiple meshes from the gradient and catchment area of multiple meshes that divide the flow path included in the mountain stream area; calculating the surface water flow rate for each multiple meshes on the basis of the rainfall and catchment area; and determining the operation regulations of railway vehicles in the mountain stream area on the basis of the limit surface flow rate and the surface water flow rate of multiple meshes.SELECTED DRAWING: Figure 1
