Bubble-diffuse type destratification system is widely applied in reservoirs with problems of water bloom caused by cyanobacteria. However, the planning methodology on the installation scale of the system has not been established. In this paper, we propose a methodology by simulating and evaluating the gradient of surface water temperature, which is known to have some relationship with occurrence of water bloom. A hydrodynamic simulation model was verified in Haji Dam reservoir, where the destratification system has been equipped. By using the model, the proposed methodology was applied to the reservoir under the condition in 2001, and the current installation scale is evaluated as proper.
