Mountain torrent disaster early warning method and device, server and storage medium

Abstract

The embodiment of the invention provides a mountain torrent disaster early warning method and device, a server and a storage medium. By monitoring data acquisition, calibrating the initial hydrological forecasting model according to the standard water flow in the monitoring data; taking the calibrated model as a target hydrological forecasting model; carrying out flood forecasting calculation on the monitoring data according to the target hydrological forecasting model; and performing evolution overflow calculation on the prediction calculation result according to the evolution overflow modelto obtain an overflow flooding analysis result of the current monitoring area, and further determining whether to generate early warning information for alarming the current monitoring area accordingto the overflow flooding analysis result. Furthermore, the monitoring data is analyzed by combining the target hydrological forecasting model and the evolution overflow model; the purposes of integrated data collection, data analysis and alarming are achieved, the effects of improving mountain torrent disaster early warning and reducing the labor cost are achieved, meanwhile, the early warning precision and the early warning efficiency are improved, and the requirement for accurate and efficient early warning of mountain torrent disasters is met.

Description

technical field [0001] Embodiments of the present invention relate to mountain torrent disaster early warning technology, in particular to a mountain torrent disaster early warning method, device, server and storage medium. Background technique [0002] Mountain torrent disasters are sudden, regional, seasonal, high incidence, and harmful. Most of them occur in mountainous areas and urban-rural junctions, mainly during the rainy season and typhoon season. It is difficult to predict and prevent them. Due to the rapid rise and fall of mountain torrents , disasters occur quickly, and disasters are avoided. The harm to residential areas in low-lying areas is particularly serious, and it is easy to cause casualties, house collapses, traffic interruptions, and damage to cultivated land and other loss of life and property. [0003] At present, the construction of the monitoring, early warning and forecasting system for mountain torrent disasters has not yet been perfected. Most are...
