IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Preliminary Research on Hydrodynamic Dispatch Method of Algal Blooms in Three Gorges Reservoir Bays
Author : WEI YIN (1), XIAOKANG XIN (2) & ZHONGPING PEI (3)
Spring algal happened in the bays area frequently after Three Gorges ReservoirĄ¯s impoundment. Algal bloom is closely related with nutrients, light, temperature and flow velocity. This paper carried out preliminary research on algal blooms hydrodynamic control method by optimizing reservoirs dispatch on main and tributary channels. Making use of software MIKE 21, a Xiangxi River-Three Gorges Reservoir integrate hydrodynamic numerical model has been established, and a series of conditions have been simulated and studied. The result shows that if Three Gorges Reservoir operates alone, velocity at Xiangxi River mouth is less than 0.05m/s, and if Xiangxi Reservoir operates alone, velocity at Xiangxi River mouth is larger than 0.05m/s in wet year. It implies that Three Gorges ReservoirĄ¯s water level change has little to do with improvement of tributariesĄ¯ velocity, but reservoir in main and tributary channels dispatch together can improve the velocity obviously, which can control algal bloom in tributary bays.
