TL;DR: In this article, the authors analyzed the wave attenuation produced by the permeable structure and proposed design formulas that can be used for the optimized hydraulic design of Jarlan-type breakwaters.
Abstract: In the present engineering practice, direct formulas are not given for the preliminary hydraulic design of Jarlan-type breakwaters: Only qualitative observations and heuristic considerations are reported. The writers analyze the wave attenuation produced by the permeable structure and propose design formulas that can be used for the optimized hydraulic design of Jarlan-type breakwaters. The proposed model, based on the linear wave theory, is validated by comparison of the theoretical results with the experimental measurements of other authors. The results show that the Jarlan-type breakwater with a single chamber gives the most effective wave reduction in the range of practical applications and that no particular configuration of the porous wall can be suggested as the best one. The size of the breakwater cannot be standardized, since the optimum hydraulic design of the structure is linked to the parameters of the design wave. Moreover, the proposed design formulas may be used to approximately predict the response of the structure to incident irregular waves.

TL;DR: In this article, the performance of a box-type floating breakwater is studied and an analytical solution of the two-dimensional linearized hydrodynamic problem is presented. But the results of the analytical results were not compared with a numerical solution of a full linear problem.

TL;DR: In this paper, the authors present a numerical modeling system named GENESIS which is designed to simulate long-term shoreline change at coastal engineering projects as produced by spatial and temporal changes in longshore sand transport.
Abstract: : This report documents a numerical modeling system named GENESIS which is designed to simulate long-term shoreline change at coastal engineering projects as produced by spatial and temporal changes in longshore sand transport. Typical longshore extents and time periods of modeled projects can be in the ranges of 1 to 100 km and 1 to 100 months, respectively, and almost arbitrary numbers and combinations of groins, detached breakwaters, seawalls, jetties, and beach fills can be represented. GENESIS contains what is believed to be a reasonable balance between present capabilities to efficiently and accurately calculate coastal sediment processes from engineering data and the limit in both the data and knowledge of sediment transport and beach change. The modeling is operated through a structured and user-friendly interface so that the operator need not become familiar with detailed aspects of the computer code. This report serves as a technical reference to Version 2 of GENESIS and is also designed to be an operator's manual by providing instructions for using the interface. The method for applying the model is described from the perspective of the needs of both engineers and planners who deal with evaluate shore- protection projects. A fully documented case study involving application of the modeling system and exercise of many of its features is provided. Sweden.
