Title:

Nature-based Shore Protection to Stabilize Estuarine Sediment

A location of estuarine shoreline between the mouths of the Lamprey and Squamscott Rivers in Great Bay, New Hampshire has experienced extensive erosion. This erosion has occurred largely due to its susceptibility to fetch-generated wind-waves from the northeast direction, as well as strong tidal current flows. The site offers another unique quality of being situated between the discharge of wastewater treatment plants upriver in Newmarket and Stratham. In the year 2021 alone, the oyster aquaculture industry brought $4.7 million into the New Hampshire economy, a 909% increase in industry value since 2013. By studying the effects of oyster growing structures on wave and current behavior, as well as the ecological benefits of oyster cultivation, oyster aquaculture has the potential to mitigate shoreline erosion and wastewater treatment byproducts, while actively contributing to the economy of New Hampshire.
