Embodiment Construction

[0067] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0068] A non-uniform multi-source flood encounter risk analysis method, characterized in that: the steps of the analysis method are:

[0069] 4) Data preparation: process the main and tributary flood series to be evaluated, and exclude the years with historical extreme values, so as not to interfere with the inconsistency analysis of the series;

[0070] 5) Inconsistency diagnosis of flood peak sequence: Based on the comprehensive diagnosis system of hydrological variation, the non-consistency diagnosis of flood peak sequence is carried out. The comprehensive diagnosis system of hydrological variation includes preliminary diagnosis, detailed diagnosis and comprehensive diagnosis, and integrates human activities and climate change. Factor ana...

Abstract

The invention relates to a non-uniform multi-source flood encountering risk analysis method. The method is characterized by comprising the following steps: 1) preparing data; 2) carrying out non-consistency diagnosis on flood peak sequences; 3) determining main and branch flood peak time sequence distribution; 4) carrying out fitting and parameter estimation on main and branch flood peak sequences; 5) constructing joint distribution; and 6) carrying out flood peak encountering analysis. According to the method, the design is scientific and reasonable, the actual encountering situation of actually measured flood sequences can be analyzed, and the flood influence evaluation can be carried out more flexibly and effectively by using a joint analysis method while the flood sequences are characterized by using the significant characteristic quantity to grasp the researched flood characteristics; a flood control response mechanism is perfected, peak shaving and peak shifting are conducted intime, life and property losses of people are reduced, and a flood control standard basis is provided for watershed hydraulic engineering construction.

Description

technical field [0001] The invention belongs to the technical field of flood frequency analysis and relates to risk analysis of flood encounters, in particular to a non-uniform multi-source flood encounter risk analysis method. Background technique [0002] Catastrophic floods are often formed by the joint action of floods from multiple sources, especially basin-wide floods, where the mutual influence between floods in main and tributary streams is particularly prominent. For larger flood peaks, flood peaks can be cut and blocked in advance to avoid flood disasters. However, for flood peaks occurring at the same time in multiple rivers in large basins, especially flood peaks generated by multiple rain areas, it is necessary to carry out timely peak shifting to prevent flood peaks from superimposing and causing further floods. Great flood. Therefore, in flood forecasting, it is necessary to consider the encounter of flood peaks of multiple rivers and accurately judge the pos...
