Analysing turbulence characteristics of flow over submerged flexible vegetated channel
Experimental investigation has been done to access turbulence characteristics just above the sparse flexible submerged vegetation zone in open-channel flow. The experimentation has been done in a tilting flume with bed covered by artificial vegetation and arranged in a regular staggered configuration. The applicability of log law is analysed above the vegetated canopy. Turbulent parameters such as velocity profiles, Reynolds stresses, turbulent intensities, quadrant analysis, turbulent production and diffusion, dissipation and stream power have been appraised to understand the hydrodynamics of vegetated channel. Results show that the log law is valid above the canopy of submerged vegetation with decreased Von-Karman constant. Maximum value of turbulent intensities and Reynolds stresses has been found above the canopy. Quadrant analysis shows that sweeps and ejections events are more dominating factors in submerged vegetated channel.
