The video tutorial covers hard engineering methods in coastal management, focusing on sea walls, rock armor, gabions, and groins. Each method's advantages and disadvantages are discussed, including social, economic, and environmental impacts. The video concludes with additional resources for further learning.

What is a primary advantage of sea walls in coastal management?

• They provide a sense of safety and security.

• They enhance the natural beauty of the coastline.

• They are inexpensive to build.

• They promote the growth of marine life.

What is a significant disadvantage of constructing sea walls?

• They promote sediment movement.

• They are easy to maintain.

• They can increase erosion at the base.

• They are visually appealing.

What is a key economic advantage of using rock armor?

• It requires frequent maintenance.

• It restricts access to the beach.

• It can be constructed quickly.

• It is more expensive than sea walls.

How does rock armor benefit the environment?

• It impedes sediment movement.

• It enhances beach aesthetics.

• It does not impede sediment movement.

• It increases wave energy.

What is a social disadvantage of gabions?

• They are difficult to construct.

• They restrict access to sandy beaches.

• They are very expensive.

• They are dangerous when damaged.

What is a major advantage of gabions in coastal management?

• They are only suitable for shingle beaches.

• They are easy to construct and last long.

• They restrict sediment movement.

• They are costly to build.

What is a primary function of groins in coastal management?

• To restrict beach access.

• To retain beach material.

• To promote cliff erosion.

• To increase wave energy.

What is a disadvantage of using groins?

• They enhance natural processes.

• They are visually appealing.

• They can cause erosion down drift.

• They are expensive to maintain.

What is an economic benefit of groins?

• They are expensive to build.

• They require frequent repairs.

• They attract tourists with wide beaches.

• They restrict beach access.

What is a social benefit of groins?

• They restrict access to the beach.

• They promote sediment movement.

• They are visually appealing.

• They are used as wind breaks by tourists.
