Gulf Coastal Resilience: informing the identification of restoration projects with maximum socio-economic and ecological benefits

Nearshore Waves

As one of the functions within the Coastal Resilience planning tool, the Nearshore Waves tool allows users to input oyster reef physical characteristics. The coastal protection model contains a series of 1-Dimensional bathymetry profiles that extend from the shoreline to deep water at fixed location along the shoreline. Additionally, offshore wave height and period input values are derived from classes of wind speed and included as inputs. The tool then computes the evolution of the wave over the bathymetry, following well established engineering equations.

When waves encounter the oyster reef, the model estimates directly the transmitted wave height shoreward of the reef by treating it as a breakwater. The empirical transmission coefficient is a function of the incident wave height right offshore of the reef, the reef physical characteristics (height, crest and base width), as well as its location along the 1D profile. When reefs are very close to the water surface, they can be quite efficient breakwaters and only transmit 3% of the incident wave height.
