Abstract:

Water circulation near the beach is very important to keep the health of ecosystems in ports and waterways. Creating a natural circulation of water from the sea into the harbor and vice versa could well reduce pollution and its damaging effects. In addition to securing watercrafts, permeable breakwaters such as: pile breakwaters and slotted breakwaters, ensure communication and natural circulation between the port and the sea to eliminate environmental pollution in port areas[1]. Many researchers have studied on the reflection, transmission and energy dissipation coefficients of perforated/slotted breakwaters. Many permeable barriers in various designs have been introduced and suggested that their main purpose was to reduce wave transmission and the force exerted on the wall. Most of the modelling that has been conducted to investigate the permeable breakwater, were experimental. Varjavand et al [1] theoretically and experimentally developed analytical model to predict the reflection coefficient, transmission coefficient, the force exerted on the wall and wave run-up on the single and double slotted breakwaters using potential concept. Ahmed et al [2] also investigated hydrodynamic responses of single and double slotted breakwaters theoretically and experimentally.
