Coastal Hazards and Management Concepts

The video tutorial covers coastal processes, focusing on erosion and accretion, and their impact on landforms. It discusses various coastal hazards like waves, sea level changes, and storm surges, and explains salt water intrusion and its effects on freshwater aquifers. The video also highlights mitigation and adaptation strategies, including evacuation plans and educational efforts to prepare communities for coastal hazards.

What are the two major processes that shape coastal landforms?

• Deposition and sedimentation

• Erosion and accretion

• Weathering and erosion

• Sedimentation and weathering

Which of the following is NOT a type of coastal hazard?

• Sea level change

• Waves

• Volcanic eruption

• Storm surge

What is eustatic sea level change?

• Local rise of sea level due to storms

• Sea level change due to tectonic activity

• Global sea level change affecting ocean volume

• Temporary rise in sea level during high tide

What is the effect of storm surges on sea level?

• They cause a continual increase in sea level

• They permanently raise sea level

• They have no effect on sea level

• They cause a temporary decrease in sea level

What causes saltwater intrusion?

• Excessive groundwater pumping

• Increased rainfall

• Volcanic activity

• Tectonic shifts

How can saltwater intrusion be prevented?

• By increasing groundwater pumping

• By stopping the construction of wells

• By building more dams

• By desalinating seawater

What is the primary effect of saltwater intrusion on agriculture?

• Increased crop yield

• Decreased soil salinity

• Improved irrigation efficiency

• Reduced crop yield

What is a key strategy for mitigating coastal hazards?

• Building more coastal properties

• Educating the community

• Ignoring evacuation plans

• Increasing groundwater pumping

Why is it important to have evacuation plans for coastal areas?

• To increase tourism

• To ensure safety during hazards

• To promote local businesses

• To reduce property prices

What role do educational efforts play in coastal hazard management?

• They promote saltwater intrusion

• They reduce the need for evacuation plans

• They increase awareness and preparedness

• They help in building more coastal properties
