Beach Improvement and Monitoring
To address the issues of shore protection and “sediment starvation” along the Winthrop Beach shoreline, a mixed-sediment beach nourishment project was designed and implemented. Unlike most beach nourishment projects in the United States, the material proposed for restoration of Winthrop Beach consists of mixed cobble, gravel, and sand sediments. The total beach fill length was approximately 1,300 linear meters and the volume was approximately 350,000 cubic meters. Losses over the first two storm seasons were minor and beach volume monitoring, combined with the mixed sediment transport modeling , were utilized to develop a more complete understanding of mixed-sediment nourishment longevity.
