• Subsidence of land

• Thermal expansion

• Removing natural vegetation

What can exacerbate a storm surge?

• High atmospheric pressure

• Removal of natural vegetation

• Increase in house prices

• Decrease in tourism

What are the two main types of coastal management strategies mentioned?

• Soft and medium engineering

• Hard and soft engineering

• Traditional and modern engineering

• Direct and indirect engineering

What is a cost-benefit analysis (CBA) used for in coastal management?

• To determine the best location for a new beach

• To compare the costs and benefits of coastal management actions

• To assess the environmental impact of coastal erosion

• To evaluate the cultural significance of coastal areas

What factor is considered when deciding on a coastal management policy related to the value of land?

• Economic value

• Aesthetic value

• Historical value

• Recreational value

What is the main goal of Integrated Coastal Zone Management (ICZM)?

• To manage coastal areas for economic development only

• To manage coastal areas as separate entities

• To manage coastal areas as a whole, considering people's livelihoods and sustainability

• To focus solely on natural processes without human intervention

What is the purpose of Shoreline Management Plans (SMPs) in the UK?

• To focus only on human activities along the coast

• To identify and manage all activities, both natural and human, within sediment cells

• To prevent any exchanges between different sediment cells

• To manage only the natural activities along the coast

What is a significant drawback of hard engineering in coastal management?

• It is low cost and environmentally friendly

• It prevents erosion in all areas without any negative effects

• It has a high cost and significant environmental impact due to the use of concrete

• It enhances natural erosion processes

Which of the following is a characteristic of revetments?

• They are visually appealing

• They require no maintenance

• They are cost effective

• They are made of natural materials

What is the main goal of soft engineering in coastal defense?

• To use hard structures to block waves

• To work with and complement the physical environment

• To increase the height of cliffs

• To remove sediment from beaches
