Coastal Sciences, Engineering & Planning: Representative Projects

As part of the Central Artery/Tunnel project, Woods Hole Group performed a detailed beach nourishment design for the shoreline of Spectacle Island, which is located within Boston Harbor. Background work to develop the beach nourishment design incorporated state-of-the-art coastal engineering numerical models combined with appropriate assumptions regarding the littoral processes. The propagation of waves from Massachusetts Bay into Boston Harbor was modeled using the refraction/diffraction model, REF/DIF1. This model predicts the transformation of waves in areas where the bathymetry is irregular and where diffraction is important, such as at Spectacle Island. The resulting wave heights, periods and directions were used as input to both longshore and cross-shore sediment transport models. These models were employed to simulate the performance of several different beach fill designs.
