Long-term erosion is considered permanent erosion that occurs over decades. Long-term erosion is caused by:
- Shore protection structures such as jetties and groins that prevent sand from being transported to the beach;
- Inadequate sediment supply to replace losses due to alongshore and offshore transport;
- Major storm-related events from which the beach is unable to recover naturally.
