Analysis of Design Rainstorm Hydrograph Based on Asymmetrical Extreme-value Copula
Taking the maximum 1-hour rainfall (rain peak), maximum 6-hour rainfall and maximum 24-hour rainfall in the Caojiang River Basin from 1967 to 2013 as samples, this paper establishes the typical typhoon rainstorm hydrograph for join trainfall distribution of three periods based on the asymmetric Arch...

| description | Taking the maximum 1-hour rainfall (rain peak), maximum 6-hour rainfall and maximum 24-hour rainfall in the Caojiang River Basin from 1967 to 2013 as samples, this paper establishes the typical typhoon rainstorm hydrograph for join trainfall distribution of three periods based on the asymmetric Archimedean Gumbel-Hougaard extreme-value copula. The main conclusions are as follows: (1) The design rainstorm value in Caojiang River Basin calculated through the joint rainfall distribution of three periods is larger than that calculated through the joint rainfall distribution of two periods and a single period. The design rainstorm hydrograph amplified at the same frequency has the optimal overall effect, which provides a new idea for the research of design rainstorm pattern. (2) According to the maximum 24-hour rainfall, the risk rate of the multi-peak rainstorm process with late main peak is the highest, and the typical design rainstorm hydrograp accordingly is the most representative. (3) The design criteria of the joint rainfall of‘OR’ return period with combination of three periods are applicable to the control of rainfall and flood in the river basin. |
