Analysis on Features of Hydrological Variation in the Seasonal Stagnant Lower Reach of Xiangjiang River

Abstract:

Based on daily measurement of the water levels and flow rates made by hydrologic stations of Xiangtan, Changsha, Xiangyin, Lujiao at lower reach, Xiangjiang River and Chenglingji in the middle reach of Yangtze River from 1980 to 2010, the analysis is made on the conditions of typical hydrologic year at the lower reaches, Xiangjiang River and middle reach of Yangtze River as well as the temporal and spatial correlation of water level of different hydrologic stations of lower reaches of Xiangjiang River and Chenglingji Station and features of variation of water level and water gradient in different typical years. A definition for seasonal stagnant river was given according to the hydrological feature of lower reaches of Xiangjiang River on the base of current domestic and international summaries and definitions regarding stagnant flows.
