摘要
The present invention relates to a system for analyzing massive floods and dam collapse based on a continuous torrential event. According to the present invention, a plurality of meteorological stations, a plurality of subwatersheds, a junction between subwatersheds, a plurality of meteorological nodes corresponding to each of a plurality of meteorological stations, a plurality of subwatersheds, a junction between the subwatersheds, an outlet of a watershed, between junctions or a channel connecting a junction and an outlet on the DEM map, a plurality of meteorological nodes, a plurality of watershed nodes, A node setting unit that maps a plurality of junction nodes, an exit point, and a plurality of channels, respectively, sets an observation period and period that are commonly applied to the plurality of weather nodes, and corresponds to each watershed node and each channel, each subwatershed and each An environment setting unit that receives detailed information of the river, a collecting unit that collects and stores meteorological data measured at each weather station according to the observation period and period, and the amount of runoff for each watershed node based on the hourly collected meteorological data Calculated and delivered to the corresponding junction node, accumulated, routed along the channel through channel tracking, finally calculated the total runoff at the exit point, and based on the continuous rain event including an analysis unit that analyzes the flood level based on this Provides an analysis system for mega-flood and dam collapse. According to the present invention, accurate rainfall-runoff analysis for continuous heavy rain events can be performed using the time-unit rainfall-runoff analysis module, and it is possible to efficiently prepare for massive floods and flooding.
