Hydrological Effect of Three Gorge Reservoir Operation on Hukou Station at Poyang Lake
Abstract: The Three Gorges Reservoir had shifted into comprehensive operation stage since 2009. This paper analyzed daily water level and discharge data of Hukou station from 1950 to 2009. The results show that the average annual discharge and water level of Hukou station decrease slightly in the past 60 years and the changes show obvious pattern of periodicity. From 2003, especially after 2006, the average annual discharge and water level have declined significantly. According to the operation rules of Three Gorges Reservoir, this paper analyzed the hydrological impacts of Three Gorges Reservoir on Hukou hydrological regime in different operation periods. It is found that the decline of discharge and water level of Yangtze River caused by the water storing of Three Gorges reservoir leads to the dry season ofPoyangLakeappearing earlier and lasting longer. However, the influence on Hukou hydrological regime is not obvious at flooding and releasing periods.
