Abstract

The invention discloses a dynamic monitoring and early warning analysis system for mountain torrent disasters, which takes the prevention and control of mountain torrent disasters as the main line, takes monitoring information as the data basis, utilizes new information technology, combines geographic information system, Internet of Things technology, statistical analysis technology, and machine learning technology , to realize the information system of dynamic early warning of mountain torrent disasters. The system uses station monitoring information as the basic data, including four subsystems: real-time rain regime subsystem, real-time water regime subsystem, flood dynamic early warning analysis system, and distributed management subsystem. The invention improves the precision and efficiency of mountain torrent disaster early warning, and improves the scientific and technological level of the water conservancy and hydropower industry.

Description

technical field [0001] The invention relates to the field of early warning of mountain torrent disasters, in particular to a dynamic monitoring and early warning analysis system for mountain torrent disasters. Background technique [0002] At present, most small watersheds lack high-precision basic geographic information data and measured hydrological data, and the calculation theory of storm and flood in small watersheds in hilly areas is not yet perfect, especially the underlying surface conditions and characteristic parameters of small watersheds, basic attribute parameters of small watersheds, and flow generation and confluence. The mechanism and so on need to be further studied. On the other hand, the occurrence of floods caused by heavy rainfall in local areas has certain randomness and variability. It is necessary to generalize the physical process clearly, and the degree of freedom is moderate to be used in models for flood analysis in areas without data or in mounta...
