MARINE & COASTAL ENGINEERING
Shoreline protection
Coastal and riverbank protection works against erosion, wave action and tidal movement.
What is shoreline protection?
Shoreline protection covers engineering works designed to reduce or prevent erosion of a coastline or riverbank caused by wave action, current, or tidal movement. Methods range from hard structural defences to softer, nature-based approaches.
Engineering application
Protection method is selected based on the erosion mechanism at the site (wave attack, current scour, tidal action), the value of the land or assets being protected, and the acceptable level of environmental change to the shoreline.
Typical project types
- Coastal land protection for developments
- Riverbank stabilisation
- Protection of existing marine or waterfront infrastructure
Common approaches
- Revetments — armour layers (rock or concrete units) placed on a sloped bank
- Seawalls — vertical or near-vertical hard structures
- Groynes/breakwaters — structures that interrupt wave energy or longshore drift

Considerations
- Protecting one section of shoreline can shift erosion to adjacent areas — requires careful coastal engineering assessment
- Environmental and regulatory approvals are typically required
- Long-term maintenance should be planned for
