- Porthcawl
- Management
- Type - Hard Engineering
- Rip Rap
- Long lasting & versatile use
- Restricts access, may be unsightly, dangerous to climb on
- Sea Wall
- Long lasting, can have promenades to promote tourism, absorb wave energy & protect from flooding
- Very expensive, considered unsightly, can restrict access & reduce sediment supply, affecting other coastal areas.
- Revetment
- Absorb wave energy, allow longshore drift & are cheaper than sea walls
- Can restrict access, be unsightly & need regular maintenance if wooden
- Tarmac beach revetment
- Unsightly, disrupts natural habitats, expensive.
- Reduce erosion & reduce wave power preventing them from going over the sea wall
- May also reduce longshore drift, which would build up the beach, perfect for tourism, but starve elsewhere of sediment.
- Rock groynes
- Stronger and look more natural than wooden ones, less expensive
- Can be dangerous to climb on, can be an obstacle for people walking & can reduce longshore drift
- Tarmac beach revetment
- Unsightly, disrupts natural habitats, expensive.
- Reduce erosion & reduce wave power preventing them from going over the sea wall
- May also reduce longshore drift, which would build up the beach, perfect for tourism, but starve elsewhere of sediment.
- Rip Rap
- Possible Questions
- Has the management been successful in preventing erosion?
- Limitation - finding the type of erosion which affects the coast because the defences have been there for so long
- Has it caused any tensions and conflicts?
- Limit - difficult to find secondary information on, may be just known locally and never printed as news because I does not affect may people
- Do the locals believe the management to be a success?
- Limit - Opinions are likely to be more biased
- If you ask a tourist they will not have any idea
- Limit - Opinions are likely to be more biased
- Have other area of the coastline been affected by the defences at Porthcawl?
- Limit - Does not measure success of the defences at Porthcawl, which I my question
- Has the management been successful in preventing erosion?
- Human
- Tensions & conflicts?
- Farmers who's land is at risk from erosion & the government who have suggested no defending that land.
- Business owners who's livelihoods are at risk because of no management
- Locals and toursists
- Dog walkers & elderly who feel the beach is restricted & may struggle getting down to it
- Locals opinions of the success
- Using our questionnaire
- Tensions & conflicts?
- Physical
- Has it been successful in doing its job
- Has it effected other areas along that stretch of coastline
- Type - Hard Engineering
- Landforms
- It's in a bay with headlands either side
- The defences have been there so long, no natural landforms are really able to form.
- Possible Questions
- Could question the effects management have had on the bay & headland.
- Pictures show the bay has not receeded
- Links to erosion question
- Pictures show the bay has not receeded
- The waves types and the erosion that they cause, leading to the formation of the bay.
- Limitation - finding out the wave type will be difficult, as well as the erosion at Porthcawl because of how long the defences have been there
- Could question the effects management have had on the bay & headland.
- Geology
- Bedrock
- Oxwich head Limestone formation
- Mudstone (Mercia group)
- Newton has Pant mawr sandstone
- Superficial Deposits
- Head clay, silt, sand and gravel
- Blown sand
- Possible Questions
- Has the geology influenced the need for defences?
- Yes, if the geology hadn't been eroded then the defences would not be needed to protect the town
- Too narrow
- The waves types and the erosion that they cause, leading to the formation of the bay.
