Wave Energy Dissipation by Using Some Different Types of Breakwaters

Abstract

This research investigates the effectiveness of three different types of permeable breakwaters experimentally (floating breakwaters, submerged breakwaters, and piled breakwaters), as often overestimated during the design process. Choosing the appropriate type of breakwater is one of the main concerns in the design of shore protection or energy dissipation measures. Several factors affect the selection of the breakwater’s type, such as the water depth at the site of the breakwater (y), the wave period (T), the wave height (H), soil conditions, and available material near the site. Different physical models have been tested under a various wave and water depth conditions to examine the efficiency of the three types of breakwaters with varying draught in floating models, crest freeboards in submerged models, and transverse spacing, arrangement, and geometry in piled models.
