Diagram/Picture 1: Groynes
Characteristics:
- Built perpendicular to the shore
- Traps sediment moving along the coast
- Helps to build up beaches on one side while causing erosion on the other side.
Diagram/Picture 2: Seawall
Characteristics:
- Vertical structure built parallel to the shore
- Designed to absorb wave energy and prevent erosion of the coastline
- Can cause increased erosion in front of the wall due to reflected wave energy
Diagram/Picture 3: Beach Nourishment
Characteristics:
- Involves pumping sand onto an eroded beach
- Helps to build up the beach and provide protection against erosion
- Maintenance is required to replace sand lost to natural processes like waves and storms
