density current plunge flow reservoir fence
Lakes and reservoirs often suffer from freshwater red-tide or freshwater blooms formed by Microcystis aeruginosa. Fences are often used to prevent freshwater blooms in lakes and reservoirs by controlling plunge flows. In this study, the effects of an inclination angle and a setting position on hydrodynamics of plunge flows are investigated experimentally. It is found form study that the plunge point moves upstream-wise and the thickness of the plunge flow become smaller when the non-dimensional setting position and the submerged length of the fence are small. It is also found that the most effective angle of the fence is 30 degree.
