The project focuses on conducting research on the process and evolution mechanism of the Yellow River ice flood disaster under changing environments, the rapid collection and dynamic monitoring technology of multi temporal and multi element ice conditions, the early warning and risk dynamic assessment technology of ice flood disasters, the key technology of joint regulation of upstream reservoir groups and sub ice zones during the ice flood period, the development of key technologies and complete equipment for rapid rescue of ice flood hazards, and the development and demonstration of the Yellow River intelligent ice prevention platform, Cracking the response mechanism of the spatiotemporal evolution of the Yellow River ice flood disaster to complex changing environments, the multi-process evolution mechanism of ice dam and ice flood under extreme weather conditions, the real-time monitoring and perception technology of multi element water land air all-weather ice situation, the early warning and prediction of ice flood disasters, and the dynamic risk assessment technology Six key scientific and technological issues, including the joint anti icing scheduling technology between upstream reservoir groups and sub icing areas, and the safe, efficient, and precise ice breaking and discharging technology that combines point line surface, have been addressed. Six sets of technical equipment have been developed for rapid collection of ice flood elements and rapid prevention and control of ice flood disasters, and a decision support platform for rapid prevention and control of ice flood disasters has been constructed.
