Abstract:
The gestationοΌ_x008c_occurrence and evolution of ice flood disasters in cold regions are closely related to the river channel-dike-flood plain system οΌRDFSοΌ‰οΌ_x008c_and the scientific assessment and prevention and control of ice flood disasters risk are of great importance. The "identification - calculation - assessment - prevention and control" of ice flood disasters risk was taken as the main line of thinking in this paper. The research progress from the following five aspectsοΌ_x009a_ causes and characteristics of ice flood disastersοΌ_x008c_numerical models of river ice and ice floodοΌ_x008c_river ice flood disasters risk assessmentοΌ_x008c_risk assessment of dyke failure and inundation during ice floodοΌ_x008c_and risk prevention and control measures of ice flood disasters were reviewed. The driving mechanism and chain effect of ice flood disasters in RDFSοΌ_x008c_disaster model of river ice evolution - ice flood backwater - dyke danger - ice flood inundationοΌ_x008c_risk quantitative assessment of ice backwater-dike burst-ice flood inundationοΌ_x008c_dyke freezing and thawing danger evolution mechanism and intelligent predictionοΌ_x008c_support system of ice flood disasters including monitoring-early warning-assessment-risk prevention and controlοΌ_x008c_the digital twin platform for "four presets" of ice flood disastersοΌ_x008c_were key directionsοΌ_x008c_which can provide important ideas for in-depth exploration and scientific management of the ice flood disasters risk in cold regions.
