Coastal Conflicts

Big Questions and Learning Outcomes

  • Today's Big Question: What conflicts happen on a coastline?

  • WALT (We Are Learning To):

    • Analyse the stakeholders involved in coastline activity and management.

    • Investigate examples of coastal conflicts between different groups.

  • Key Instruction: Follow through the slides and complete the tasks in detail.

  • Note: The content will not be reviewed in class, so students are encouraged to finish any work during the lesson.

Offshore Conflict in the UK

Diagram Task

  • Instruction: Draw a diagram in your notebook.

  • Labeling: Use two colours (red and black) for different labels.

Map Annotation Task

  1. Annotate the map with the groups involved in offshore activities.

  2. Identify three potential conflicts that could occur due to these activities, explaining the associated problems.

Coastal Flooding Risk

Big Questions and Learning Outcomes

  • Today's Big Question: How much of a risk is coastal flooding?

  • WALT:

    • Understand the causes of coastal flooding.

    • Analyse methods of mitigating coastal flooding.

  • Do Now Activity:

    • Provide three reasons for requiring flood defences at Medmerry.

    • Give three reasons for requiring flood defences in Sri Lanka.

    • Discuss which management scheme was most successful and explain the rationale.

Causes of Coastal Flooding

  • Coastal flooding can primarily be caused by two factors:

    • Storm Surges:

      • Major threat due to low-pressure systems that raise high tide levels.

      • Strong onshore winds can drive the 'raised' sea towards the coast, potentially breaching defences.

    • Tsunamis:

      • Generated by earthquakes, leading to extensive flooding impacts.

      • Particularly relevant to coastal areas like Sri Lanka.

Flooding Trends

  • Storm surges and tsunamis are periodic but can pose ongoing threats to specific coastal regions.

  • Cities like Venice face constant and increasing flood risks due to various geographic and climatic factors, including global warming and rising sea levels.

Reducing Coastal Flood Risks

Prediction Methods

  • Historical record analysis to identify areas frequently affected by serious flooding—focus on high-risk areas.

  • Accurate forecasting of potential hazard events, including tropical storms and tsunamis.

  • Predictions should encompass timing, location, scale, strength, and expected damage.

Prevention Strategies

  • Defences: Constructing barriers along vulnerable coastlines.

  • Evacuation Shelters: Providing safe zones for communities facing flooding.

  • Land Zoning: Relocating housing and businesses away from high-risk areas.

  • Urban Planning: Strategically planning developments to stay clear of flood-prone zones and ensuring new buildings are resilient.

  • Monitoring Systems: Implementing advanced warning systems for potential floods.

  • Education Programs: Teaching the community how to respond to flooding warnings effectively.

Impact Reduction Techniques

  • Education: Explaining that well-informed individuals can react appropriately to flood warnings, significantly mitigating impacts.

  • Climate Change Effects: Discussing how rising temperatures and sea levels can exacerbate flooding risks in coastal environments.

  • Predictive Techniques: Using historical data to refine predictions can lead to better preparedness and response strategies.

  • Prevention Strategies: Implementing defences and strategic planning to minimize damage from flooding events in the long term.
