Coastal Management Strategies

What do soft engineering methods involve?

• Building structures to stop erosion and flooding to protect the coast.

• Groynes

• Ecologically sensitive methods to manage erosion and floods

• Seawalls

What is a Sea Wall?

• large boulders piled up on the beach in steel cages.

• A wooden barrier built at right angles to the beach.

• Areas of the coast are allowed to erode and flow naturally.

• A solid wall that is used to separate the land from the sea.

Why is it important to protect our coastline?

What is beach nourishment?

• Large boulders piled up on the beach in steel cages.

• Replaces beach or cliff material that has been removed by erosion or longshore drift

• Areas of the coast are allowed to erode and flood naturally.

• A wooden barrier built at right angles to the beach.

What is erosion?

• process whereby weathered material (for example: soil, rock fragments) is removed from the landscape; agents of erosion include water, wind and mass wasting

• an inlet of the sea at a river’s mouth; where the river’s current (fresh water) meets the sea’s tide (salt water)

• the study of landforms and the processes that formed them and continue to shape them over time

• a deep inlet of the sea almost surrounded by land, with a narrow mouth to the sea

• A

What are groynes?

• large boulders piled up on the beach in steel cages.

• a wooden barrier built at right angles to the beach.

• an area of land completely surrounded by water

• the process of cutting down trees

What do hard engineering methods involve?

• Building structures to stop erosion and flooding to protect the coast

• Ecologically sensitive methods to manage erosion and floods

• Coastal retreat

• Longshore drift
