![]() In the numeric modeling, the static FB structures attenuated the wave energies more effectively than the dynamic structures due to the lack of motion response. A wave-by-wave analysis was performed to determine the significant wave height, as well as a singular wave analysis that is comparable between each data set. The OpenFOAM solver, olaFoam, developed in 2015 by Pablo Higuera for wave generation and absorption, was applied to a numerical replicate of the FB structure in the FIT wave channel for ease of comparison and validation. The physical testing was performed in the Florida Institute of Technology (FIT) wave channel at 1:1 scale using a rectangular, wooden FB structure. Additionally, the FB motion response to wave interaction is simulated using a static structure and a dampened, dynamic structure. The dimension parameters were compared to the transmission coefficient, which is a nondimensional value traditionally used to compare the transmitted wave height to the incident wave height. The transmission coefficient is physically tested in a wave channel and numerically simulated in OpenFOAM for a rectangular FB structure to determine the effects of the draft parameter (dr/d) and the breadth parameter (B/L). FB structures attenuate wave energies and are transportable, allowing for removal once the living shoreline restoration is established. Based on previous studies, it has been found that habitat restoration will be successful if the wave height is reduced from 0.20 m to 0.10 m with the use of a FB structure. The design significant wave climate of the IRL in a 0.6 m water depth had an incident significant wave height of 0.20 m with a wave period of 1.6 s. ![]() Opportunities and challenges associated with the design and construction of coastal structures with different levels of integrating landscape-based solutions are identified across projects, and guidelines for the design and construction industry are provided.This study examines the design and implementation of floating breakwaters (FB) in the Indian River Lagoon (IRL) to support and protect living shoreline restoration projects from damaging wave climates. ![]() and Singapore are investigated, which take a 'design by research' approach through testing innovative approaches to achieve multiple benefits. Two case studies of coastal management projects in the U.S. This paper reviews existing and emerging projects that propose modified coastal structures including bioengineered breakwaters and living shorelines with natural and nature-based features that have multiple benefits such as reducing flood risks and mitigating the loss of intertidal and shallow water biodiversity. Emerging studies determine the importance of ecological knowledge and landscape-based solutions in informing the design of coastal infrastructures however, there are limited number of projects that demonstrate the most effective design approaches. A shift from 'coastal armoring' and hard engineered 'defense systems', to ecologically informed infrastructures has created opportunities and challenges in designing structures that can perform beyond engineering goals and provide ecological and social benefits. Sustainable adaptation to sea-level rise has been a growing concern for coastal management authorities, engineers, ecologists, urban planners and designers. Sea-level rise poses major challenges to coastal landscapes and communities.
