Starter quiz
- What is coastal erosion?
- The process by which coastal land is worn away by natural forces. ✓
- The process of adding sand to beaches.
- The process of building structures along the coast.
-
- What is longshore drift?
- Sudden erosion of sand by strong offshore winds.
- Formation of waves that move directly toward the shore.
- Waves moving along the beach at an angle, carrying sediment. ✓
-
- What is sustainability?
- Development focusing solely on current needs.
- Development meeting current needs without compromising future generations. ✓
- Development ignoring future implications.
-
- What is the significance of cost and benefit analysis?
- To evaluate the economic implications of strategies. ✓
- To ignore environmental impacts.
- To only focus on social aspects.
-
- How is a spit formed?
- 1⇔Longshore drift moves sand along the coast.
- 2⇔Sand accumulates where the coastline changes direction.
- 3⇔Deposits extend outwards, forming a narrow strip of sand.
- 4⇔The spit continues to grow as more sediment is deposited.
- 5⇔A curved end forms due to wave refraction or current changes.
- What is an impact of climate change on coastal erosion?
- Rising sea levels increase shoreline erosion. ✓
- Reduced wind causes less wave activity.
- Decreased rainfall prevents sediment movement.
- Stronger tides reduce erosion along coastlines.
-
Exit quiz
- What is managed retreat in coastal management?
- Building barriers to stop waves from reaching the coast.
- Relocating people and structures away from the coast. ✓
- Planting vegetation to stabilise sandy beaches.
- Strengthening existing structures against erosion.
-
- What best describes hard engineering in coastal management?
- Building structures to resist wave action and erosion. ✓
- Using natural materials to stabilise the coast.

- Creating policies for sustainable land use.
-
- What is a common concern of environmentalists regarding coastal management?
- Increased access to beaches for the public.
- Loss of natural habitats due to construction. ✓
- Enhanced biodiversity from new projects.
- Improved water quality in coastal areas.
-
- What is a positive aspect of using groynes in coastal management?
- They prevent all types of coastal erosion completely.
- They create new habitats for marine life in the area.
- They increase the width of beaches by trapping sand. ✓
- They require no maintenance once installed.

Lesson Details
Key learning points
- Coastal management aims to protect communities and environments.
- There are two main types of coastal management strategy.
- Different stakeholders may have different views on coastal management.
Common misconception
Managed retreat is when the land is allowed to erode without any direction.
Managed retreat allows for certain areas to erode or flood in a controlled manner. This approach is often chosen for low value land, where it can create natural habitats and reduce long term maintenance costs.
Keywords
Value - how important an area is either socially, economically or environmentally
Hard engineering - using artificial structures to protect coastlines from erosion and flooding
Soft engineering - making use of natural processes to reduce erosion and flooding in a way that minimies environmental impact
Stakeholder - any groups or individuals involved in or interested in changes being made at the coast
