Effect of a Submerged Vane-Field on the Flow Pattern of a Movable Bed Channel with a 90° Lateral Diversion

This laboratory study focused on the effect of a submerged vane-field flow pattern and bed morphology near inside entrance reach movable 90° lateral diversion. The system was modelled under live conditions for water discharge ratio ?0.2. Two experiments were run until equilibrium reached: with without installed close to diversion control transfer sediments into channel. associated 3D field measured in great detail. load diverted reduced by approximately one quarter due action vane-field. vanes prevented formation vortex main channel, upstream diversion’s entrance, thus contributing that decrease. They also created channel started at most further decreased amount entering separation zone larger vanes, but conveyance balanced through slightly deeper scour trench therein. structures described confirmed measurements turbulent kinetic energy.
