Abstract
Sea transportation is one of the main methods of moving goods between different countries in the world. In this regard, ports play an extremely important role and breakwaters are very important as the main structure of coastal protection. There are different types of breakwaters, including traditional rock mass breakwaters, platform breakwaters, vertical breakwaters, combined breakwaters, and special breakwaters. Due to cost reduction in construction, caisson breakwaters are used in deep waters. In the design and construction of these breakwaters, the reflection coefficient, wave overtopping and stability of the breakwater are important issues that make designers face many challenges. In order to improve the performance of caissons, various solutions have been proposed by researchers, among them Jarlan caissons in which perforated plates were placed in front of the caisson. In the following, after presenting the solution of creating holes on the front face of the caisson, many researchers have evaluated various variables to obtain the optimal plan in this regard. The collection of these researches confirm the optimal performance of caisson breakwaters with holes and some of them suggest new geometries on how to create holes. This optimized performance includes both better hydraulic response and, in some cases, reduced forces, which will improve stability. At the same time, other researches have been conducted on breakwaters without holes, and researchers have tried to improve their performance by changing the geometry of these caissons.
