Prevention of Coastal Erosion

Many Ways To Prevent Erosion Breakwater (above or below water) Retaining walls (rock/sandbags) Groynes Fencing/Netting Planting vegetation No movement zones Replace eroded sand

Breakwaters (above and underwater) Prevents waves from breaking on shore and being destructive with their undertow.

Retaining Walls Reduces erosion from breaking waves on shore.

Groynes In the case of longshore drift, material moving down the beach collects on the windward side of the groyne slowing movement down the beach.

Fencing/Netting Prevents movement of on shore sand by wind and waves by creating barrier (like with groynes).

Planting Vegetation Roots of plants to help hold sand in place.

No Movement Zones/Movement Zones Keeps disruptive traffic minimized.

Replacing of Sand Slows erosion from pushing inland because new material replacing the old.
