Sand Stabilization with American Beachgrass on the North and Middle Atlantic and Great Lakes Coasts.

摘要

Foredunes function as a reservoir of sand to nourish eroding beaches during storms, and as a levee to prevent the inland penetration of waves and storm surges. Dunes are often created and maintained by the action of beach grasses which trap and hold wind-blown sand. Erosion will occur if this vegetation is damaged (as by drought, disease, over-grazing, or waves during severe storms). Damaged or destroyed dune systems can usually be restored by planting beach grasses.
