Enhancing dune dynamics

Overview

Dune landscapes play a significant role in coastal defense: their topography forms a natural barrier to protect upland areas from flooding. On beaches of sufficient width, natural sediment transport by wind grows the dune system, while vegetation can capture and stabilize sand. The placement of dredged sand can be utilized to construct new dunes or augment existing landscapes. In addition to enhancing coastal protection, these nourished dunes can be designed to support habitat creation and recreation.
