how important an area is either socially, economically or environmentally

using artificial structures to protect coastlines from erosion and flooding

making use of natural processes to reduce erosion and flooding  in a way that minimies environmental impact

any groups or individuals involved in or interested in changes being made at the coast

Costs and benefits of management strategies

Geography

The role of geology in coastal erosion

The role of climate, marine and sub-aerial processes in coastal erosion

The influence of sediment transportation and deposition on coastal landscapes

The effect of human activities on coastal landscapes

Change in a named coastal landscape

Risks from coastal flooding

Using GIS to visualise the impact of physical and human processes on coasts

This unit teaches pupils about coastal processes and landforms. Pupils will learn about the physical processes operating at the coast and about the formation of distinctive landforms of coastal erosion and deposition. Pupils will also learn about the importance and options of coastal management.

Coastal landscapes

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 is managed retreat in coastal management?

Building structures to resist wave action and erosion.

Using natural materials to stabilise the coast.

Enhancing habitats to protect coastal ecosystems.

Creating policies for sustainable land use.

What best describes hard engineering in coastal management?

Increased access to beaches for the public.

Loss of natural habitats due to construction.

What is a common concern of environmentalists regarding 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.

What is a positive aspect of using groynes in coastal management?

The process by which coastal land is worn away by natural forces.

The process of building structures along the coast.

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.

Development focusing solely on current needs.

Development meeting current needs without compromising future generations.

Development ignoring future implications.

To evaluate the economic implications of strategies.

What is the significance of cost and benefit analysis?

Longshore drift moves sand along the coast.

Sand accumulates where the coastline changes direction.

Deposits extend outwards, forming a narrow strip of sand.

The spit continues to grow as more sediment is deposited.

A curved end forms due to wave refraction or current changes.

Rising sea levels increase shoreline erosion.

Decreased rainfall prevents sediment movement.

Stronger tides reduce erosion along coastlines.

What is an impact of climate change on coastal erosion?
