Coastal erosion may be caused by hydraulic action, abrasion, impact and corrosion by wind and water, and other forces, natural or unnatural. Over time the coast generally evens out. The softer areas fill up with sediment eroded from hard areas, and rock formations are eroded away.
What are coastal erosion hazards?
Coastal erosion is a natural process that continually affects the Oregon coast. Erosion becomes a hazard when human development or public safety is threatened. Beaches, sand spits, dunes, and bluffs are constantly affected by waves, currents, tides, and storms, resulting in chronic erosion, landslides, and flooding.
How do you mitigate coastal processes?
Mitigation Methods for Coastal Erosion
- Dune rehabilitation: Drift fencing and dune re-vegetation prevent the loss of wind-blown sand inland and help with dune stability.
- Green belts: series of trees in a number of rows to protect the coast from onslaught of waves.
What do you think is causing the extreme erosion at Rockaway beach?
