In some closed water body the dynamics of substances in the water are affected by windinduced turbulence based on mechanical disturbances and convective flow based on thermal disturbances. Wind-induced flow and waves are produced when mechanical disturbances act on the water surface. The production of turbulent energy at the water surface and its transit through the density interface play an important role in the dynamics of the water environmental substances contained in the water. When the surface in the closed water body is partially covered with floating vegetation, it is considered that wind waves and wind-induced flow should be to some extent affected by the vegetation, especially in small reservoirs, ponds and creeks that have less surface area upon which the wind can act. Therefore, it is important to clarify the effect of floating vegetation on windinduced flow and wind waves generated by wind shear. We experimentally considered the turbulence characteristics of wind-induced flow and wind waves in the closed water body with floating vegetation using a test tank. This presentation includes a discussion of the impact of floating vegetation on wind-induced flow and wind wave characteristics caused by mechanical disturbance in a closed water body. The result indicate that the energy of wind-induced flow is affected by the existence of floating vegetation and that the wind wave characteristics changed as the floating pattern of the vegetation changed.
