The invention provides an urban inland inundation black spot inland inundation simulation method and device, and the method comprises the steps: obtaining a net rainfall according to the difference between an obtained rainfall and a natural consumption rainfall; inputting the net rainfall into an inland inundation water accumulation simulation model to enable the inland inundation water accumulation simulation model to output an inland inundation water accumulation simulation value of the inland inundation black spot so as to determine an inland inundation simulation result of the inland inundation black spot according to the inland inundation water accumulation simulation value, wherein the waterlogging and ponding simulation model is obtained by training according to historical net rainfall and historical waterlogging and ponding results in the historical rainfall monitoring data. According to the method, the net rainfall waterlogging and ponding corresponding relation is established, so when waterlogging simulation is implemented subsequently, the corresponding waterlogging simulation result can be calculated through known rainfall only according to the actual rainfall, and basic data such as terrain and elevation do not need to be utilized; the technical problems that existing urban inland inundation analogue simulation basic data is high in dependence, low in calculation efficiency and poor in applicability are solved.
Description
technical field [0001] The present application relates to the field of urban disaster monitoring, in particular to a waterlogging simulation method and device for urban waterlogging black spots. Background technique [0002] With the further development of urbanization in China, from megacities to supercities, the size, population, and property of cities have increased substantially, which means that the losses caused by waterlogging disasters will be even greater. On the other hand, under the influence of climate change, extreme rainfall in cities is also showing a trend of increasing and strengthening. In the future, urban waterlogging problems will become more frequent, and the disaster losses will be more serious. In the face of increasingly severe urban waterlogging disasters, the reduction of casualties and property losses caused by urban waterlogging through refined management has attracted much attention. With rapid development, how to provide technical support for ...
