چکیده
Artificial reefs are effective measures to improve the marine ecological environment and increase fishery production. However, there several geometries being investigated nowadays their setup, including spacing between groups of them, can provide dissimilar effects on hydrodynamics. To enhance understanding this topic, in paper, focus is mainly M-Type artificial that will be adopted Juehua Island, Liaodong Bay, China. An experimental campaign was carried out order simulate influence unit reef may have local flow field Particle Image Velocimetry (PIV) technique has been implemented velocity maps. The results showed with velocity’s current approaching reef, height, length area upwelling back vortex rise reefs. Furthermore, when comparing different geometrical configurations similar currents maximum values both were obtained 1.25 L. Finally, entropy method used evaluate under four kinds based hydrodynamic characteristics economic cost. comprehensive score for all followed L > 1.50 0.75 1.00 Therefore, it suggested original design should increased by 25% M-type put into practice. Additionally, after having completed a comparative analysis, recommended further change group monocases. By executing adjustment, cost reduced 10%, range result consequently achieve greater benefits less input. study preliminary reference construction from perspective theory

Artificial reefs in Florida have been especially popular since the 1970s. With the advent of State Legislative funding in the 1990s, numerous local government and private interests have been able to develop reefs. The principal purpose is to enhance recreational fishing opportunities. But there are an increasing number of reefs being built as scuba diving sites and also to repair or mitigate da...
