Beach nourishment Breach stabilisation Dune regneration Land use management Creating marshland Coastal realignment
What’s a shoreline management plan
A plan within each cell with the aim to protect important sites and not effect other places, local authorities co operate
ICZM
considers all elements with the aim to protect coastal zone whilst allowing people to use it
9 types of hard engineering
Sea wall Revetments Gabions RIP rap Fortunes Breakwaters Earth bank Tidal barrier Tidal barrage
Explain beach nourishment
Where sand and shingle are added to beaches to create wide beaches to reduce erosion of beach and cliffs
Explain dune regeneration
Sand dunes created a restored by no Ishman or stabilisation of sand Talk to the barrier between land and sea absorbing wave energy
Explain land use management
Wooden walkway and fenced offareas that prevent walkers gaining access to dunes reduces vegetation loss
Explain creating marshland
Planting appropriate vegetation to stabilise the sediment and reduce the speed of waves which reduces erosive power leading to less flooding
Explain coastal realignment
Also known as managed retreat involves breaching an existing defence and allowing It to flood the land behind so vegetational eventually colonise and become a marshland
2 disadvantages of hard engineering
Expensive and disrupts natural processes
Why is soft energy usually more sustainable
Usually cheaper requires less time and money to maintain it’s also designed to integrate with natural environments and can create marshland and sand dunes which are important habitats
make it more sustainable because it has a low environmental impact and economic cost
