Abstract
The Fort Pierce Shore Protection Project, located in St. Lucie County, Florida, nourishes a 2.09-km Atlantic Ocean shoreline south of Fort Pierce Inlet on Florida's east coast. After each beach nourishment, historical measurements indicate the beach fill erodes nonuniformly, with a hotspot along the northernmost 0.7 km requiring nourishment after about two years of normal wave regimes. However, storms can quickly erode the beach fill and require nourishment earlier than the normal two-year interval. Longshore transport carries most of the eroded fill to the south, creating a strong feeder-beach effect. This study evaluated several designs and combinations of coastal structures to produce more uniform erosion throughout the project area and to increase the nourishment interval. The study applied several state-of-the-art numerical models to evaluate the two-dimensional effect of a "coastal structures† alternative on hydrodynamics, waves, sediment transport, and beach morphology.
