Experimental Studies on Hydrodynamic Performance of an Artificial Reef
A two dimensional experimental study has been conducted on non perforated and perforated artificial trapezoidal reefs in order to plan and prescribe suitable coastal protection measures against erosion. Multiple units of reef have been tested in order to reduce the wave transmission. However, the results for a single reef are presented in this paper. It mainly focuses on the influence of perforations and water depth on the artificial reef as a possible wave attenuator. The percentage of reduction in wave transmission is quantified. The results on the variations of transmission, reflection and loss coefficients along with the dynamic pressure exerted on the reef due to regular waves as a function of relative reef width for its different relative depths of submergence are reported in this paper.
