Title : Characteristics of Backflows from the Yangtze River to the Poyang Lake After Using of the Three Gorges Reservoir
LI Yu, , XU Quanxi,
Abstract : The change of the relationship between rivers and lakes affected by the Three Gorges Reservoir has been a major focus in recent years. The backflows from the Yangtze River to the Poyang Lake is the main feature of the relationship, and its variation characteristics and occurrence conditions are still controversial. The hydrological data since 2003 of the Jiujiang, Balijiang and Datong hydrological station located in the Yangtze River and the Duchang, Kangshan and Hukou hydrological station locat

Zhong Liang, , Wang Shu, , Pan Yunwen, , Zhang Jianmei, , Xu Guangxiang, , Ni Zhihui,
Abstract : In order to slove the problem that the representative particle size method is difficult to accurately quantify the roughness of the gravel bed surfaces (GBS), the statistical theory was introduced to study the roughness properties of natural GBS. A series of loose-stacked GBS were prepared by using particles with different size and composition. Based on the analysis of the laser scanning data of the above GBS and the existing test results, the relationship between the statistical parameters of b
