An Experimental Investigation of Turbulence Features Induced by Typical Artificial M-Shaped Unit Reefs

Artificial reefs are considered to have the function of repairing and improving coastal habitat increasing fishery production, which mainly achieved by changing regional hydrodynamic conditions. The characteristics flow turbulence structure an important part characteristics. Different methods used evaluate performance artificial according their shape purpose for reef was built. For this study, M-shaped unit reefs, be put into area Liaodong Bay, were selected as research object never been fully investigated before. Experimental tests conducted assess effect these on vertical longitudinal turbulent intensity under different hydraulic conditions geometries, datasets collected using Particle Image Velocimetry technique implemented within experimental facility. distribution variation analyzed, main results obtained can confirm that in area, there extremely clear boundary. Furthermore, influence identified larger than turbulence, position where maximum appeared close velocity measured. Finally, demonstrate low typically located front reef, general is upwelling zone, more intense between two monocases. These important, because they provide local authorities with specific knowledge about what could will implemented, therefore, actions taken consideration geometrical setup suggested optimal solution study.
