TL;DR: In this article, the physical processes of regular wave trains impacting on a perforated breakwater were studied and the numerical solutions were further analyzed to describe the hydrodynamic processes, identify the limitations of the analytical theory and the scale effects in the laboratory experiments.
Abstract: In this paper we study the physical processes of regular wave trains impacting on a perforated breakwater. The breakwater consists of an array of vertical rectangular columns and a backwall. We have performed numerical simulations in which reflection coefficients have been calculated based on the Mansard and Funke (1980) theory and compared with laboratory data and analytical solutions (Kakuno et al. 1992, Kakuno & Liu, 1993). The numerical solutions will be further analyzed to describe the hydrodynamic processes, identify the limitations of the analytical theory and the scale effects in the laboratory experiments.

TL;DR: In this paper, the lee wind side of the delta is considered as a marina, and the main purpose of this marina is used for happy vacation time, such that the wharf is designed for the anchoring of yacht and hydrofoil cruiser, etc., the breakwater is need to constructed convenient to be fishing.
Abstract: Due to the abundant supply of sediment from the rivers, the west coast of Taiwan has shown a rapid accretion in history. As a result of this large areas could be reclaimed, such as the delta North of Putai -Wai-Shan-Ding sand barrier. In recent years, however, sediment supply is reduced due to river training and flood control. Consequently, the coastal area is now subject to erosion as the net sediment transport exceeds the supply to the beach. Therefore, shore protection is going to be cultivating the Australian pine tree by the Chia-Yi County Government. Since the relatively well protected location of the area with regard to both waves and wind, no special navigational problems have to be envisaged. For the point view of whole development, it is easily planned the lee wind side of the delta as a marina, and wharf could be simply constructed as a floating type for sightseeing and cargo handling between this island to offshore island (such as P'eng-Hu or King-Meng, etc.). The main purpose of this marina is used for happy vacation time, such that the wharf is designed for the anchoring of yacht and hydro-foil cruiser, etc., the breakwater is need to constructed convenient to be fishing. Siwwing beach, beach park and some facilities for sightseeing are planned and designed in this offshore area for utility of the coastal management.

TL;DR: In this article, an alternative design has been proposed by Charier, based on a berm breakwater concept, which consists of a rock armour allowed to reshape to a stabilized S profile under storm wave action.
Abstract: The extension project of Roscoff-Bloscon harbour includes a 550 m long rubble mound breakwater. Invitation to tender for the construction works was based on a 6.3 m 3 ACCROPODE TM armoured breakwater. An alternative design has been proposed by Charier, based on a berm breakwater concept. This kind of breakwater consists of a rock armour allowed to reshape to a stabilized S profile under storm wave action. The design studies included preliminary calculations of the breakwater profile and physical testing at Oceanide wave flume. These studies confirmed the stability and overtopping performances of the proposed breakwater. They allowed the Owner to adopt this solution under technical, economical and environmental performance perspective.
