“…For instance the trend that wave attenuation is greatest when the crest of the structure is at or above the still water level, with little wave attenuation during submergence (Allen & Webb, 2011;Webb & Allen, 2015) should also apply to oyster reef breakwaters (Chauvin, 2018;MacDonald, 2018;Servold, Webb, & Douglass, 2015;Wiberg, Taube, Ferguson, Kremer, & Reidenbach, 2018). In a controlled hydrodynamic study within a newly deployed oyster reef living shoreline, Spiering, Kibler, and Kitskoudis (2018) found that wave attenuation was maximized (83 ± 5%) when water levels were 1 cm below the crest of the reef structure.…”

“…a higher, narrower crest may attenuate as much as a lower, wider crest, with the latter being akin to how naturally occurring oyster reefs attenuate waves (Allen & Webb, 2011 Whitman & Reidenbach, 2012). This would result in a combined ecological-engineering approach that acknowledges the heterogeneity of shorelines and dynamic nature of living organisms.…”

1.Oyster reef living shorelines have been proposed as an effective alternative to traditional coastal defence structures (e.g. bulkheads, breakwaters), with the benefit that they may keep pace with sea-level rise and provide co-benefits, such as habitat provision. However, there remains uncertainty about the effectiveness of shoreline protection provided by oyster reefs, which limits their broader application. 2.We draw evidence from studies along the east and gulf coasts of the United States, where much research and implementation of oyster reef restoration has occurred, to better define the existing gaps in our understanding of the use of restored oyster reefs for shoreline protection. 3.We find potential disconnects between ecological and engineering functions of reefs. In response, we outline how engineering and ecological principles are used in the design of oyster reef living shorelines and highlight knowledge gaps where an integration of these disciplines will lead to their more effective application. Synthesis and applications.This work highlights the necessary steps to advance the application of oyster reef living shorelines. Importantly, future research should focus on appropriate designs and conditions needed for these structures to effectively protect our coasts from erosion, while supporting a sustainable oyster population, thereby providing actionable nature-based alternatives for coastal defence to diverse end-users.

Sea dikes protect low-lying hinterlands along many coasts all around the world. Commonly, they are designed as embankments with grass covers or grey revetments accounting for the prevailing hydraulic loads. So far, incorporation of ecological aspects in the dike design is limited. With regard to increasing environmental awareness and climate change adaptation needs, the present study reviews methods for ecological enhancement of sea dikes and discusses limitations and challenges related to these methods. In doing so, one key aspect is to maintain dike safety while increasing the ecological value. Potential for ecological enhancement of sea dikes has been found regarding natural or nature-based solutions in the foreshore, dike surface protection measures (vegetated dike covers, hard revetments and dike roads) and the dike geometry. While natural and nature-based solutions in the foreland are investigated thoroughly, so far only few experiences with ecological enhancements of the dike structure itself were gained resulting in uncertainties and knowledge gaps concerning the implementation and efficiency. Additional to technical uncertainties, engineers and ecologists meet the challenge of interdisciplinary collaboration under consideration of societal needs and expectations.
