Abstract:

More than 25 million dollars have been spent on three adjacent nourishment projects extending along 10 miles (16 km) of central Pinellas Country on the Gulf Coat of Florida. The three projects are similar in size and design but each differs in some combination of source location and material, and in the method of construction. Redington Beach, on the south end, was completed in 1988, Indian Rocks Beach, on the north end, was finished in 1990, and Indian Shores, the middle project, completed the project in December, 1992. All three projects have been monitored continuously since completion including profile measurements, shoreline mapping, sediment analysis and wave climate. Although there has been various lengths of monitoring due to the completion dates of the respective projects, the performance to date is different for each one. The distribution of sediments by coastal processes is influenced by the method of construction; both how the material was removed and delivered to the beach, and the constructed profile of the nourished beach. Considerably less shoreline migration took place where the re-nourishment profile was followed. The nature of the sediment, especially the shell content is an important factor in performance. Because of the different ages of the projects, it is not possible to compare performance for more than the initial six months of each.
