Review on computational methods of hydrological design values in changing environment
摘要
Abstract
The advances on the estimation of hydrological design values in changing environment in terms of univariate,multivariate design value estimation and uncertainty analysis of design values were systematically summarized.The series reconstruction method,weighted synthesis of distributed functions and varying-parameter probabilistic distribution model were reviewed with the emphasis for univariate hydrological design value estimation.In multivariate hydrological design value estimation,the varying-parameter joint distribution function model considering the inconsistency of marginal distribution and structural parameters of multivariate was analyzed and it is pointed out that the method for calculating the multivariate return period or design value cannot be applied to the multivariate cases under inconsistent conditions.This paper puts forward the problems to be further explored in the field of hydrological design value estimation under changing environments,including the design flood adjustment of the constructed projects,estimation of the combined design values in multivariate cases and the reliability evaluation of the calculation results.关键词
