Abstract
The Yangtze River to Chaohu Lake section is the starting section of the Yangtze to Huaihe Water Diversion project.It adopted a dual-line water diversion scheme via the Caizihu and Xizhaohe lines,passing through the two major navigable lakes,Caizihu and Chaohu,and had conditions suitable for gravity-driven water diversion.Conducting a probabilistic distribu-tion analysis of gravity-driven water diversion could provide a scientific basis for optimizing water resource scheduling in the project.This paper,in combination with the project layout and the hydraulic connections between the river and lakes,proposed a judgment equation for the conditions of gravity-driven water diversion and carried out research on the distribution of the probability of gravity-driven water diversion via the Caizihu line and the Xizhaohe line.The analysis indicated that the average number of days with gravity-driven water diversion for both lines over the years was basically around 30～35 days,accounting for about 10%of the whole year,with the distribution periods largely overlapping and mainly concentrated in April to June.The optimized water resources scheduling of the project can be combined with the distribution conditions of gravity-driven water diversion.By enhancing the water level control of Chaohu Lake and creating favorable water level combinations between the river and the lakes,more opportunities for gravity-driven water diversion can be obtained.This is of great significance for sav-ing the operational costs of the project.关键词
