Project Objectives
• Evaluate effectiveness of the dune at reducingoverwash and retaining sand in the swash zone
• Assess performance of clay-cored dune and sand duneat both nourished and unnourished sites
• Determine effectiveness of low volume beach fill toreduce erosion of underlying clay layers
• Evaluate effectiveness of different grain sizes andnourishment rates
• Evaluate effectiveness of groins at retaining sand incells and performance of geotextile structures
