![]() The results of these investigations are presented in this paper. Extreme waves generated by hurricanes, together with storm surges, have led to severe damage and even failures in many offshore structures.This paper presents a novel submerged breakwater design suitable for protecting coastal bridges and other infrastructure. With an in-house code, a constrained interpolation profile (CIP)-based model is employed to simulate this process. The model domain used in the present study consisted of a single shore parallel submerged breakwater, with side slopes of 1:5, superimposed on an alongshore uniform beach with an equilibrium cross-shore profile (h Ax 2/3).The bed material was assumed to consist of sand with D 50 of 0.2 mm, which is common on natural beaches. A comprehensive laboratory investigation to evaluate the performance characteristics of the submerged breakwaters of various types and shapes, permeable and impermeable was undertaken. Laboratory experiments are performed to investigate the hydrodynamics around a submerged breakwater due to regular incident waves. (CSM) to dynamically simulate the fully coupled hydroelastic interaction between nonlinear ocean waves and a submerged horizontal plate breakwater (SHPB). Investigation of the U-shape submerged breakwater performance by the finite-different scheme shows better performance than the semicircular one. Recourse has to be taken to laboratory studies to provide the necessary information regarding the performance characteristics of submerged breakwaters. Design of the submerged horizontal plate breakwater using a fully coupled hydroelastic approach. Submerged breakwaters are low-crested offshore structures that are built shore-parallel in shallow water, with their crests at or below water level. Theoretical analysis of the problem has not proved satisfactory primarily because of the difficulties in quantifying the energy losses that always accompany these wave - structure interactions. However quantitative information available about the hydraulic behaviour of these submerged breakwaters is rather limited. Submerged breakwaters have been effectively used to protect harbour entrances, to reduce siltation in entrance channels, against beach erosion, and for creation of artifical fishing grounds. Submerged Breakwater for Kahului Harbor: Structural Design and Construction Procedu re Phase I, Technical Report, HDOT Contract Award No. In situations where complete protection from waves is not required, submerged breakwaters offer a potentially economic solution. Submerged breakwater is a barrier with its crest at or slightly below the still water level. ![]()
