Lesson 2: Core Concepts: coastal management
Duration: 50 minutes
Starter Activity (5 minutes)
Review Previous Lesson
Quick recap: write 3 key points from Lesson 1 on coastal management. Check them against the notes below.
Main Content (35 minutes)
Key Concept: Coastal erosion and flooding threaten homes, businesses, farmland and infrastructure. The UK has over 2,800 km of coastline at risk from flooding and over 1,700 properties at risk from coastal erosion. Coastal management aims to protect people and property, but it is expensive and can have unintended consequences.
Definition: Hard engineering involves building artificial structures that absorb wave energy, prevent erosion or stop flooding. These are typically expensive, visually intrusive and require ongoing maintenance.
Definition: Soft engineering works with natural processes to manage the coastline. It is generally cheaper, more sustainable and more environmentally friendly than hard engineering, but may be less effective against extreme events.
Key Facts: The Holderness Coast in East Yorkshire is the fastest-eroding coastline in Europe. It retreats at an average rate of 1.8 metres per year, with some sections losing up to 5 metres in a single storm. Since Roman times, the coast has retreated approximately 4 km.
Exam Tip: Always consider both the benefits and problems of each management strategy. The most common exam question asks you to evaluate different approaches - you must show both sides and reach a justified conclusion.
Geography Exam Tips — Coastal Management: 1. For Coastal Management questions, always name specific case studies with factual detail 2. Use geographical terminology precisely (e.g. specific processes, not vague descriptions) 3. Consider social, economic and environmental perspectives in your evaluations 4. Support your points about Coastal Management with data, statistics or named examples 5. For 'assess' or 'evaluate' questions, reach a clear judgement supported by evidence
| Term | Meaning | Example |
|---|---|---|
| Sea wall | £5,000-10,000/m | 75-100 years |
| Rock armour | £1,000-4,000/m | 30-50 years |
| Gabions | £500-1,000/m | 10-15 years |
| Groynes | £150-200K each | 25-30 years |
| Beach nourishment | £5-20M | Natural appearance; recreation; tourism |
| Dune regeneration | £2-10K/100m | Natural; habitat creation; low maintenance |
| Managed retreat | £500-5K/ha | Habitat creation; sustainable; cheap |
Practice (10 minutes)
Q: Describe one hard engineering strategy used to protect the coast. (2 marks)
Answer: Rock armour involves placing large boulders (1-2 tonnes) at the base of cliffs (1 mark). The boulders absorb and deflect wave energy, reducing erosion of the cliff behind (1 mark).

Lesson 3: Application: coastal management
Duration: 50 minutes
Starter Activity (5 minutes)
Quick Recall
Recall the key terms: Key Concept, Key Facts, Exam Tip. Define each in one sentence.
Main Content (35 minutes)
Parent/Teacher Guide: Let your student attempt each question alone first, then compare with the model answer. Award method marks for correct working even if the final answer is wrong.
Q1: Describe one hard engineering strategy used to protect the coast. (2 marks)
Answer: Rock armour involves placing large boulders (1-2 tonnes) at the base of cliffs (1 mark). The boulders absorb and deflect wave energy, reducing erosion of the cliff behind (1 mark).
Q2: Explain how groynes protect the coastline. (4 marks)
Answer: Groynes are wooden or concrete barriers built at right angles to the coastline, extending into the sea (1 mark). They trap sediment being transported by longshore drift on the up-drift side (1 mark). This builds up a wider beach which absorbs more wave energy naturally (1 mark). However, groynes starve the down-drift coast of sediment, increasing erosion rates there, which is a significant disadvantage (1 mark).
Q3: Compare hard and soft engineering approaches to coastal management. (6 marks)
Answer: Hard engineering uses artificial structures to resist wave energy - sea walls reflect waves and prevent flooding, but are expensive (£5,000-10,000/m) and ugly (1 mark). Rock armour and gabions absorb energy but have shorter lifespans (1 mark). Soft engineering works with natural processes - beach nourishment adds sand to create wider beaches that absorb energy naturally, looking attractive and providing recreation (1 mark). Dune regeneration uses vegetation to stabilise sand and create natural defences (1 mark). Hard engineering is generally more effective at protecting property but can cause problems down-drift (e.g., groynes starving beaches) (1 mark). Soft engineering is cheaper and more sustainable but may be less effective in extreme storms and needs ongoing maintenance (1 mark).
Q4: Using a named UK coastline, assess the effectiveness of coastal management strategies. (9 marks)
Answer: The Holderness Coast in East Yorkshire is Europe's fastest-eroding coastline, retreating at 1.8 m/year. At Hornsea, hard engineering including a sea wall, rock armour and groynes has effectively protected the town (1 mark). The groynes have built up the beach, providing recreation and protection, costing over £5 million (1 mark). However, at Mappleton, the 1991 rock groynes that protect the village have accelerated erosion down-drift at Great Cowden to 3-4 m/year by trapping sediment (1 mark). This shows hard engineering can protect one area while worsening problems elsewhere - an unsustainable approach (1 mark). Soft engineering alternatives like beach nourishment at Hornsea provide natural protection but need regular replenishment every 5-10 years (1 mark). Managed retreat is applied at Spurn Head, creating habitat but accepting land loss (1 mark). The cost-benefit approach means towns are protected while farmland is not, creating inequality (1 mark). An integrated approach combining hard and soft engineering where appropriate, with managed retreat where protection is not economically justified, would be most effective and sustainable (1 mark). However, any approach must consider the impact on neighbouring sections of coast (1 mark).

Main Content (35 minutes)
Exam-Style Question
Attempt a past-paper style question on coastal management from the exam board past paper finder (see Resources), then mark it against the scheme.
Exam Tips: Always give both advantages AND disadvantages for each strategy | Use the Holderness Coast as your case study - know Mappleton's down-drift impact | For evaluation questions, consider effectiveness, cost, sustainability and environmental impact | Explain the down-drift problem of groynes - examiners look for this specifically | Know the difference between hard and soft engineering and be able to justify a preference | Use cost-benefit analysis to explain why some areas are protected and others are not
Common Errors: Watch Out! Students often write vague answers without specific geographical evidence. Wrong: Writing generalised statements like 'it causes problems' Correct: Using specific data and named examples, e.g. 'the 2010 Haiti earthquake killed over 200,000 people due to poor building quality' Students often confuse causes and effects. Wrong: Mixing up what caused the event with what resulted from it Correct: Clearly separate causes (why it happened) from effects (what happened as a result) Students often describe rather than evaluate. Wrong: Listing strategies without assessing their effectiveness Correct: Weighing up strengths and weaknesses of each approach and reaching a supported judgement
