GENERATION LIMIT LINE OF SEDIMENT DISASTER, SETTING METHOD OF EVACUATION REFERENCE LINE AND WARNING REFERENCE LINE AND ITS PROGRAM, AND WARNING EVACUATION ASSISTING SYSTEM USING GENERATION LIMIT LINE, EVACUATION REFERENCE LINE, AND WARNING REFERENCE LINE

摘要

PROBLEM TO BE SOLVED: To provide a method by which a non-linear generation limit line of a warning sediment disaster for each slope face or torrent, an evacuation reference line, and a warning reference line can be accurately and easily set and also to provide a warning evacuation assisting system using a program for executing the method, a non-linear generation limit line of sediment disaster for each slope face or each torrent, an evacuation reference line, and a warning reference line.;SOLUTION: The warning evacuation assisting system is provided with a process computing a latent dangerousness of generation of sediment disaster, a process for classifying slope faces or torrents into groups, a process for computing the average value of latent dangerousness of the plurality of groups, and a process for computing the weight of a connection line of the intermediate layer and the output layer by using a neural network regarding the judgement boundary face expressing generating dangerousness of sediment disaster at every classified group to establish the non-linear generation limit of sediment disaster of each slope face or torrent, the evacuation reference line, and the warming reference line.;COPYRIGHT: (C)2003,JPO
