Optimization of Hydrological Methods for Suitable Ecological Flow in the Middle Reaches of Huaihe River
摘要
Abstract
To determine the optimal ecological flow and appropriate ecological flow calculation methods for the middle reaches of Huaihe River,seven hydrological methods are used to calculate the suitable ecological flow processes for the two sections based on the monthly average flow data from the Wujiadu and Xiaoliuxiang hydrological stations between 1985 and 2021,and the applicability of each method is evaluated based on hydrological rhythm,deviation rate,satisfaction and suitability.The results show that:(a)in terms of hydrological rhythm,the monthly frequency method and the NGPRP method perform significantly worse in simulating natural flow compared to the other methods;(b)in terms of the composite evaluation of suitability,the Tennant method,improved Tennant method and VMF method demonstrate the best performance in terms of the monthly flow deviation rate,and the Tennant method,improved Tennant method and NGPRP method exhibit clear advantages in monthly flow satisfaction rates,while all methods perform well regarding monthly flow suitability,in which,the improved Tennant method and VMF method have the highest monthly comprehensive suitability indices;and(c)the improved Tennant method,optimized based on the long series flow data of Cs/Cv,is identified as the most suitable hydrological method for calculating ecological flow in the middle reaches of Huaihe River,and the calculated monthly ecological flow ranges for the two sections are 75.9-1 010.6 m3/s and 89.4-1 077.6 m3/s,respectively.This study provides a quantitative basis for the rational development of water resources in Huaihe River Basin.关键词
