Book Description
Wave transmission is a leading parameter determining the response of the shoreline to a detached breakwater, reef, or spur attached to a jetty. To improve the predictive capability of the shoreline response numerical model GENESIS, published empirical formulas for the wave transmission coefficient were incorporated to calculate time-dependent wave transmission and shoreline response. Simulations for different structural configurations, wave climates, and water levels demonstrate the functional utility of time-dependent wave transmission on shoreline response predictions. Results indicate that variable wave transmission is of significance for modeling the response of the beach to submerged and emergent near-surface structures. Predictions of the model are examined in application to a functional design of a submerged spur being studied as a possible sediment-control measure for the north jetty at Grays Harbor, WA. Results show that for design applications, beach response under time-varying forcing cannot be anticipated with a constant transmission coefficient. The improved capability is expected to have wide applicability.

Book Description
Detached breakwaters can be a viable method of shoreline stabilization and protection in the United States. Breakwaters can be designed to retard erosion of an existing beach, promote natural sedimentation to form a new beach, increase the longevity of a beach fill, and maintain a wide beach for storm damage reduction and recreation. The combination of low-crested breakwaters and planted marsh grasses is increasingly being used to establish wetlands and control erosion along estuarine shorelines. This report summarizes and presents the most recent functional and structural design guidance available for detached breakwaters and provides examples of both prototype projects and the use of available tools to assist in breakwater design. Functional design guidance presented includes a review of existing analytical techniques and design procedures, functional design considerations, and data requirements. The chapter on structural design guidance includes static and dynamic breakwater stability and methods to determine performance characteristics such as transmission, reflection, and energy dissipation. Also included is a discussion of numerical and physical modeling as tools for prediction of morphological response to detached breakwaters, and a case example of a breakwater project designed and constructed at Bay Ridge, Maryland.
