Living Shoreline Solutions

Living Shoreline Solutions

Living shoreline concepts are on the leading edge of technological development in coastal engineering. These living shoreline solutions increase the biodiversity along coastal fringe marsh and on the open Gulf of Mexico shoreline.

CHE has been on the forefront of designing living shoreline solutions to prevent shoreline erosion, stimulate nearshore habitat development, and promote oyster growth. For example, CHE designed a living shoreline concept utilizing proprietary oyster reef products for the Bio-Engineered Oyster Reef Project (LA-08). The project was successfully constructed in 2011. Another project, the Living Shoreline Demonstration Project, is located in St. Bernard Parish, LA and will protect over 20 miles of fringing marsh by using multiple living shoreline concepts and products. CHE is evaluating multiple technologies and their ability to reduce marsh edge erosion and increase oyster growth. CHE is also providing the Louisiana Coastal Protection and Restoration Authority (CPRA) with a comprehensive review of experience and data on living shoreline products and their performance.

In order to determine a proposed solution’s expected performance, a thorough analysis and evaluation is required. CHE has the tools and experience needed to optimize the design by understanding the interaction between the proposed solution and the environment. CHE utilizes numerical modeling tools, such as 2D-V and 3D computational fluid dynamics modeling tools, to analyze various technology’s ability to reduce wave energy transmitted past the structure and to determine the hydraulic loading on the structures. These results are used to design more effective projects.
