2.4. Coastal Management

• One goal of coastal management is to conserve natural habitats and biodiversity.


  True
• Match the coastal process with its associated threat:

  1️⃣ Erosion

  2️⃣ Flooding

  3️⃣ Deposition

  4️⃣ Habitat loss

  5️⃣ Longshore drift

  6️⃣ Pollution
• Match the coastal process with its associated threat:

  Erosion ↔️ Flooding

  Deposition ↔️ Habitat loss

  Longshore drift ↔️ Pollution
• What is the primary cause of coastal flooding?

  Rising sea levels
• What are hard engineering techniques used for in coastal management?

  Defending against erosion
• What is a major advantage of hard engineering techniques?

  Immediate protection
• Soft engineering uses natural processes and materials to protect coastlines from erosion and flooding
• Dune stabilization protects coastal ecosystems from severe storms.

  True
• Hard engineering involves building physical structures to defend against erosion and flooding
• Coastal management aims to protect communities and infrastructure
• Match the coastal management approach with its description:

  Hard engineering ↔️ Building physical structures

  Soft engineering ↔️ Using natural methods
• Hard engineering involves building structures such as groynes to defend against erosion
• Effective coastal management is crucial to protect coastal communities, infrastructure, and natural resources
• Pollution is a major threat to coastal waters and environments.


  True
• Match the hard engineering technique with its description:

  Sea walls ↔️ Prevent erosion with concrete structures

  Groynes ↔️ Trap sediment perpendicular to the shore

  Breakwaters ↔️ Reduce wave energy offshore
• Hard engineering techniques can disrupt natural coastal processes.


  True
• Steps in soft engineering methods:

  1️⃣ Beach Nourishment

  2️⃣ Dune Stabilization

  3️⃣ Mangrove Restoration
• Match the coastal management approach with its key methods:

  Hard Engineering ↔️ Sea walls, Groynes, Breakwaters

  Soft Engineering ↔️ Beach nourishment, Dune stabilization, Mangrove restoration
• Soft engineering uses natural methods to protect coastlines.

  True
• There are three primary approaches to coastal management.

  False
• Arrange the following steps in coastal management from general goals to specific methods:

  1️⃣ Define coastal management goals

  2️⃣ Identify coastal processes and threats

  3️⃣ Choose appropriate engineering approach

  4️⃣ Implement hard or soft engineering methods
• What natural method is used in soft engineering to protect coastlines?

  Beach nourishment
• Coastal management is the strategic process of controlling and protecting coastal areas to balance human activities with natural processes
• Integrated Coastal Zone Management (ICZM) considers environmental, economic, and social factors.


  True
• Soft engineering includes methods like mangrove restoration to protect coastlines from flooding
• What drives the need for coastal management?

  Dynamic coastal processes
• Effective coastal management helps balance human activities with coastal processes
• Why are hard engineering structures often considered aesthetically unappealing?

  Negatively impact environment
• What is the primary advantage of beach nourishment?

  Absorbs wave energy
• What is the key goal of coastal management?

  Balancing human activities
• What is the primary goal of coastal management?

  Balance human activities with natural processes
• What does hard engineering in coastal management involve?

  Building physical structures
• Conserving biodiversity is a key goal of coastal management.


  True
• Soft engineering enhances natural beauty and is environmentally friendly.


  True
• Effective coastal management balances human activities with coastal processes.


  True
• Hard engineering techniques are inexpensive to maintain.

  False
• Hard engineering structures are often aesthetically unappealing.


  True
• What is the purpose of groynes in coastal management?

  Trap sediment and reduce longshore drift
• Dune stabilization involves planting vegetation to hold sand in place.

  True
• Soft engineering may be less reliable in severe storms compared to hard engineering.
