More specifically, in one embodiment of the present application, the high-precision image information includes the topography of the underlying surface, land use conditions, and residential land conditions.
Specifically, in one embodiment of the present application, the intended edit data includes historical flood information and custom extreme rainfall process information; wherein the historical flood information comprises a start time, an end time and the like of a selected typical storm flood; the self-defined extreme rainfall process information comprises deduction starting time, deduction ending time, early rain condition, early river water condition, early reservoir water condition, early work condition, rainfall process in deduction period, heavy rain center moving process, deduction target, deduction ending condition and the like.

The method comprises the steps of dividing one drainage basin into a plurality of sub-drainage basins by GIS software, wherein the accuracy of predicting the sub-drainage basins of an outlet section which is easy to generate flood disasters can be improved in the process of establishing the minimum critical surface rainfall by dividing the sub-drainage basins. When dividing the sub-river basin, the area of a single sub-river basin of the hilly terrain is more than 10 square kilometers and less than 50 square kilometers, and the area of a single sub-river basin of the deep mountain terrain is more than 50 square kilometers; the sub-river basin division among the river basins flowing into different rivers should be separated, so that the rainfall of the river flowing into the sub-river basin is accurately calculated.

Specifically, in one embodiment of the application, the dynamic characteristics of flood evolution in a submerged area are provided by calculating the evolution process of simulated water flow in river channels, flood lands and flood waterlogging processes formed by heavy rain through the constructed san-View equation group, namely, the time-space change, the water depth and the flow velocity of a submerged range are obtained, and the time-space change of the submerged range is the change of the water depth and the flow velocity in time and space.
