PROBLEM TO BE SOLVED: To integrally manage the respective simulation tools to visually and intelligibly display simulation of debris flow in a short time on an image of a GIS.SOLUTION: In a debris flow high speed simulation tool part 100 of a debris flow flooding area high speed simulation device 10, a meshing part 101 meshes LP data of a database 200 for LP data, and a binarization part 103 converts the meshed LP data into binary data. Then, a lowest river line automatic drawing part 150 performs overlap display of a primary mountain stream by a layering part 500, and a flooding simulation range setting part 110 generates a flooding simulation frame Wi on the basis of the downstream end P2. A specific range two-dimensional tomographic model calculation part 120 determines altitude data within a specific range by using the binary data corresponding to the flooding simulation frame Wi to be simulated by a debris flow flooding simulation result display tool 160. |
