Abstract
Nowadays, a selective withdrawal system (SWS) in a dam is essential for the conservation of water quality in the reservoir. However, we cannot say that the operation of SWS has been fully examined in Japan. On the other hand, in the United States, there are many methods of operation. For example, some dams use three or more gate levels, operated simultaneously, to blend the desired water quality. To make clear the efficiency of this operation, we conducted numerical simulations using the one-dimensional water quality simulation model, DYRESM-CAEDYM, developed by CWR. The simulated results indicated that this operation has a greater potential for controlling water quality in the reservoir, especially when it is combined with the surface and mid-layer intake operation.
