Embodiment Construction

[0027] The technical solution of the present application will be described in detail below in conjunction with the accompanying drawings.

[0028] The method for deriving the design flood hydrograph of the present application, said method includes: determining that the first frequency is a standard frequency; under said standard frequency, obtaining a design flood hydrograph; ensuring the design flood peak and Under the premise that the design flood volume remains unchanged, the smooth standard design flood process line is obtained by smoothing the zigzag area on the design flood process line; according to the standard design flood process line, the standard design flood peak and each duration The standard design flood volume of the time period; the standard design flood peak is used as the flood peak of a typical flood, and the standard design flood volume of each duration time period is used as the flood volume of the typical flood of each duration time period correspondingly...

Abstract

The invention provides a method for inquiring into a design flood hygrograph. The method includes the steps that the first frequency is determined to be the standard frequency; under the standard frequency, the design flood hygrograph is obtained; on the premise that it is ensured that the design flood peak and the design flood volume in the design flood hygrograph are not changed, the smooth standard design flood hygrograph is obtained by conducting smoothing on a zigzag area on the design flood hygrograph; the standard design flood peak and standard design flood amounts of all duration time periods are obtained according to the standard design flood hygrograph; the standard design flood peak serves as the flood peak of typical floods, the standard design amounts of all the duration time periods serve as the flood amounts of the typical floods of all the duration time periods, and the design flood hygrograph of at least one second frequency different from the standard frequency is inquired into.

Description

technical field [0001] The invention relates to the field of engineering hydrology, in particular to a method for deriving and designing a flood process line. Background technique [0002] In engineering hydrology, based on the basic hydrometeorological and watershed characteristic data, it is possible to analyze the local hydrological law, and according to the characteristics of the project and the requirements of planning and design, it is possible to predict and estimate the hydrological situation of the future project life, and provide information for determining the project. Scale of Design Flood or Design Runoff. [0003] A flood process contains several characteristics, such as flood peak and flood volume. Generally, their frequency of occurrence is not equal to each other. Moreover, the process itself has no concept of frequency, so the return period or frequency of any actual flood process are indefinable. The so-called design flood, in essence, refers to a specif...
