Coastal management explained
Human intervention in coastal landscapes aims to mitigate flood and erosion risks through various strategies.
Read the full explanation
Traditional approaches often rely on hard engineering, using artificial structures like sea walls to deflect wave energy, or soft engineering, such as beach nourishment, which works with natural processes to dissipate energy. Increasingly, management has shifted towards sustainable approaches that consider the entire coastal system. Shoreline Management Plans (SMPs) dictate policies like 'managed retreat' for specific sediment cells. Integrated Coastal Zone Management (ICZM) broadens this by coordinating all stakeholders to balance environmental, economic, and social needs across the wider coastal zone.
Your focus
- Compare the effectiveness and impacts of traditional hard and soft engineering approaches to coastal flood and erosion risk.
- Explain the role of Shoreline Management Plans in determining sustainable coastal defence policies.
- Evaluate the importance of Integrated Coastal Zone Management in balancing the needs of diverse coastal stakeholders.
Coastal management exam tips
Marking Points
- Distinguish between hard engineering (e.g., groynes, sea walls) and soft engineering (e.g., dune regeneration) in managing erosion and flood risk.
- Evaluate the cost-benefit and environmental impacts of traditional coastal defence strategies.
- Explain the principles of Shoreline Management Plans (SMPs) and the four policy options: hold the line, advance the line, managed realignment, and no active intervention.
- Analyse how Integrated Coastal Zone Management (ICZM) provides a holistic, sustainable approach by involving multiple stakeholders and considering entire sediment cells.
Examiner Tips
- 💡Always evaluate management strategies using specific, named examples of coastal locations where they have been implemented.
- 💡Consider the unintended consequences of human intervention, such as how protecting one area might accelerate erosion downdrift.
- 💡When discussing sustainable approaches, weigh up the conflicting interests of different stakeholders, such as local residents versus environmental conservationists.
Common Mistakes
- Using SMP and ICZM interchangeably; correction: SMPs focus specifically on shoreline defence policies for sediment cells, whereas ICZM is a broader framework managing all coastal activities and stakeholders.
- Assuming hard engineering is always the most effective solution; correction: acknowledge that hard engineering can disrupt sediment cells, causing terminal groyne syndrome, making soft or sustainable approaches preferable.
- Failing to link management strategies to both flood risk and erosion risk; correction: explicitly state whether a strategy is designed to prevent inundation (flooding) or land loss (erosion), or both.
