Reservoir operation rules for controlling algal blooms in a tributary to the impoundment of Three Gorges Dam

An attempt is made in our study to develop reservoir operation rules that would reduce the level of algal blooms in the near-dam tributaries. The reservoir operations can further incre...

| Tóm tắt: | Since the first impoundment of Three Gorges Dam in 2003, algal blooms occur frequently in the near-dam tributaries. An attempt is made in our study to develop reservoir operation rules that would reduce the level of algal blooms in the near-dam tributaries. The reservoir operations can further increase the water exchange between the mainstream of the Three Gorges Reservoir and the Xiangxi River tributary and thus move a larger
amount of algae into the deep water where it would die. Analysis of the model results indicated that water is charge fluctuations consisting of a lower night-time valley-load flow and a larger flow component to satisfy daytime peak load during short-term operations (within a day), the rise in water level during the medium-term operation (e.g., over weeks), and the combination of these two during the long-term operation (e.g., over months) can provide feasible reservoir operation rules in the non-flood season for TGR. |
