Problems solved by technology

[0004] The traditional flood frequency analysis is to distinguish the flood formation mechanism according to the flood occurrence season and the weather type before the flood, and then carry out the flood frequency analysis on this basis. Mechanisms do not make distinctions in a reasonable way, reducing the accuracy of flood frequency analysis

Abstract

The invention relates to a flood frequency analysis method and device and computer equipment. The method comprises the following steps: according to a flood runoff peak value of a target drainage basin, determining the frequency of a target flood event reaching the flood runoff peak value in the target drainage basin caused by each rainfall type in a plurality of rainfall types corresponding to the target drainage basin, and according to the frequency of the target flood event in the target drainage basin caused by each rainfall type, determining the frequency of the target flood event in the target drainage basin. Therefore, the flood source difference is considered, the frequency of the target flood event occurring in the target drainage basin under the influence of different climates (rainfall types) is determined, the accuracy of determining the frequency of the target flood event occurring in the target drainage basin is improved, a flood control strategy suitable for the target drainage basin can be determined, and the flood control effect is improved.

Description

technical field [0001] The present application relates to the technical field of water conservancy engineering, in particular to a flood frequency analysis method, device, computer equipment and storage medium. Background technique [0002] Under the background of global warming, the activities of different weather systems such as the tropical convergence zone, the Northwest Pacific subtropical high, and the southwest monsoon will change to varying degrees. One of the important effects of these weather systems is to cause rainfall, which in turn causes flooding. [0003] The construction of water conservancy projects is one of the effective measures to prevent floods in river basins. Flood frequency generally refers to the cumulative frequency of occurrence of flood characteristic values ​​(such as peak runoff). That is to say, within a multi-year period, the characteristic value is equal to or exceeds a certain number of possible occurrences, which can also be converted in...
