Abstract

This paper conducts a comprehensive review of the wave dissipation performance of various types of breakwaters in marine engineering. Over time, breakwaters have undergone significant evolution, and modern ones are constructed using advanced materials to enhance the efficiency of wave energy dissipation. They can be categorized into vertical, sloped, floating, and permeable types, each possessing distinct wave dissipation characteristics, physical principles, advantages, and disadvantages. Vertical breakwaters primarily reflect wave energy but can potentially cause strong reflections, which may have adverse effects in certain areas. Sloped breakwaters utilize the principles of kinetic energy conversion and wave breaking to dissipate energy, making them suitable for a wide range of coastal conditions. Floating breakwaters offer flexibility and adjustability to different wave conditions, while permeable breakwaters allow for water exchange while still reducing wave energy, which is beneficial for maintaining the ecological balance of the coastal area. The choice of breakwater type depends on factors such as wave conditions, topography, and environmental impact. In the future, breakthroughs in materials, design, and technology are anticipated to improve the performance of breakwaters. The selection and combination of breakwater types should take into account local conditions and requirements to ensure the effective protection of coastlines and marine facilities.
