  2. By reducing the impact of waves on the shoreline
  3. By creating a barrier that prevents erosion
  4. Both A and B
Question 3 Multiple Choice (Single Answer)

What is the primary goal of beach nourishment as a strategy for mitigating coastal erosion?

  1. To restore lost beach sand and protect coastal infrastructure
  2. To create new beaches for recreational purposes
  3. To enhance marine biodiversity and habitat
  4. To reduce the impact of storm surges
Question 4 Multiple Choice (Single Answer)

Which of the following is a natural strategy for mitigating coastal erosion?

  1. Planting vegetation along the shoreline
  2. Constructing artificial reefs
  3. Building breakwaters
  4. Replenishing beaches with sand
Question 5 Multiple Choice (Single Answer)

How does the construction of breakwaters help in mitigating coastal erosion?

  1. By dissipating wave energy before it reaches the shoreline
  2. By trapping sand and sediment, promoting beach growth
  3. By creating a barrier that prevents erosion
  4. Both A and C
Question 6 Multiple Choice (Single Answer)

What is the primary purpose of implementing setback policies in coastal areas?

  1. To restrict development in erosion-prone areas
  2. To promote sustainable coastal development

  1. By dissipating wave energy before it reaches the shoreline
  2. By trapping sand and sediment, promoting beach growth
  3. By creating a barrier that prevents erosion
  4. Both A and B
Question 11 Multiple Choice (Single Answer)

What is the primary purpose of implementing zoning regulations in coastal areas?

  1. To control the type and intensity of development
  2. To protect sensitive coastal ecosystems and habitats

  1. By dissipating wave energy before it reaches the shoreline
  2. By trapping sand and sediment, promoting beach growth
  3. By creating a barrier that prevents erosion
  4. Both A and C
Question 14 Multiple Choice (Single Answer)

What is the primary goal of implementing coastal monitoring and assessment programs?

  1. To track changes in coastal erosion rates and patterns
  2. To identify vulnerable areas and prioritize mitigation efforts
  3. To assess the effectiveness of coastal erosion mitigation strategies
