発明の名称 (英語) LOCAL INFORMATION ASSIMILATION DEVICE, METHOD AND PROGRAM FOR REAL-TIME FLOOD HAZARD MAPPING UPDATE
発明の概要(英語) A flood hazard mapping device 1 equipped with: a storage unit 23 which, for a floodplain A that has been divided into multiple unit sections a, stores the result of a flood simulation executed under multiple conditions, and similarity information indicating the hydrological similarities between the unit sections; an observation data acquisition unit 33; a reproduction flood data creation unit 34 that creates reproduction flood data on the basis of results from multiple flood simulations and observation data; a difference data acquisition unit 35 that determines the difference between the observation data and the reproduction flood data; and a flood hazard map creation unit 36 that creates a flood hazard map by using the similarity information to reflect the difference with respect to the reproduction flood data.
従来技術、競合技術の概要(英語) BACKGROUND ART
Flooding of the river flood caused by water or the like to reduce the damage caused by an object such as, by flood (the basic twenty-seven year May revision date of the second word) is a drawing of a strip, the traffic category and each target country and a prefecture where the river and flooding the governor in the case where it is assumed that the flooded water flood zone is designated as assumed and defined as the area, the countermeasure against the specific city the river flood damage (the basic twenty-seven year May revision date of the second word) is the first of the thirty-two threads, a particular country of the river and flooding the city by city traffic category is assumed that the flood zone, flood zone is designated as assumed that the city is determined.Under these defined, each of the river flooding or the like in a local water hazard map is constructed on the assumption that the resident or the like are provided.
Conventional, water hazard map, for example, the original flooding (flooding at the time of the flowing water river such as flooding and overflow from the range of mountain-ringed region) is divided into a plurality of unit areas, the flow rate of the breakage point different from the water and overtopping boundary conditions created by the simulation results are integrated.However, this is assumed in advance is carried out under the boundary conditions for the simulation result, the occurrence of flooding of a river or the like actually occurs is different from the condition of the simulation, it is assumed that flood hazard map in locations where no possibility that the water is generated.Therefore, the actual flood acquired at the time of observation of the intrusion of water in real time to reflect the data hazard is demanded a technique for creating a map.
Is Patent Document 1, an advance order to the inundation simulation result, and flooding to reflect the actual measurement data analysis system is described.In this system, the original flooding is divided into a plurality of unit areas, the coefficient of roughness of each unit area, a point bank, an analysis parameter and the flow rate and the like and over the two-dimensional unsteady flow model simulation in real-time with the water, the actual flood water depth or the like acquired at the time of flooding the observation data is fed back to the parameters of the analysis of the simulation result of the processing are sequentially modified.
