Norfolk/Odisha Case Studies Flashcards
Where is the East Norfolk Coast located? What are examples of settlements/important locations there? - Norfolk/Odisha
The East Norfolk Coast is located in the East Anglia region of the UK, adjacent to the North Sea. Settlements include Happisburgh, Winterton, Sea Palling and Bacton. Furthermore, Bacton is home to a gas terminal, while behind Sea Palling is the Norfolk Broads.
At what rate is the East Anglian Coast eroding? (m/year) - Norfolk/Odisha
The East Anglian Coast is eroding at a rate of 2m/year.
How much coast has been lost on the East Norfolk Coast between 1600 and 1850? - Norfolk/Odisha
250m of coast has been lost between 1600-1850 at the East Norfolk Coast.
What type of coastline is the East Norfolk Coast? What are the impacts of this? - Norfolk/Odisha
The East Norfolk Coast is a drift-aligned coastline, moving sediment Southwards. This leads to the loss of sediment along the coast, making this section of coastline extremely vulnerable to flooding.
When did a storm damage Happisburgh? How many people died? - Norfolk/Odisha
A storm damaged Happisburgh in 1953, with 53 people killed.
What mass movement processes take place on the East Norfolk Coast? - Norfolk/Odisha
Landslides and cliff slumping have taken place along this coast, with rapid mass movement exacerbated by runoff over the cliffs (which permeates into the ground and weakens the rocks) and groundwater flows.
What are the cliffs on the East Norfolk Coast composed of? - Norfolk/Odisha
Cliffs on the East Norfolk Coast are composed of glacial till, silt, clay and sands. Mainly materials deposited by advancing ice during the ice age.
How does runoff weaken the cliffs on the East Norfolk Coast? - Norfolk/Odisha
Runoff over cliffs can permeate through small inlets on cliffs, moistening and weakening cliffs that are already made of unstable rock. This means that mass movement processes such as landslides and rockfalls occur on the coast.
What traditional coastal management processes existed at Happisburgh ? - Norfolk/Odisha
Groynes, rock armour and revetments had been used at Happisburgh to protect the beach and coastal communities.
How many properties were damaged at Happisburgh in 1996? - Norfolk/Odisha
6 properties were damaged at Happisburgh during a storm in 1996.
What are the social/economic/environmental factors and considerations of SMP6? - Norfolk/Odisha
Social: must maintain the safety and security of the coastline, while some residents disagreeing with location or lack of defences available at the coast.
Economic: sea defences negatively impact tourism and are expensive, targeted at areas with high land value.
Environmental: aims to maintain and protect biodiversity along the East Norfolk Coast, wishes to guard natural habitats along the coast.
What stakeholders/participants are involved in SMP6? - Norfolk/Odisha
Stakeholders and participants in SMP6 include the environment agency, North Norfolk District Council, local borough councils and local residents.
What is the SMP strategy at Bacton? Why is this? - Norfolk/Odisha
The SMP strategy at Bacton is hold the line, aiming to protect and guard the gas terminal on the coast which provides 1/3 of the UK’s natural gas and acts as a link to oil fields and Europe.
What interventionist management strategies are being used at Bacton? - Norfolk/Odisha
Bacton has seen the continued use of concrete sea-walls and rock armour to guard the gas terminal, while new groynes are being constructed to maintain the beach and absorb wave energy.
What future impacts/decisions may SMP6 have to take at Bacton? - Norfolk/Odisha
SMP6 May result in beaches South of Bacton being starved of sediment and eroded due to groyne use. May mean that beach nourishment has to be used, or that the gas terminal will need protections with headlands.
What is the SMP strategy at Happisburgh? Why is this? - Norfolk/Odisha
SMP6 is employing a strategy of managed realignment at Happisburgh. This is due to the fact that there is limited flood risk at this settlement because of the steep relief, making the use of coastal defences economically unsustainable.
What strategies/defences are being employed at Happisburgh? - Norfolk/Odisha
Happisburgh has seen moderate defences implemented such as rock armour. However, redevelopment plans, architectural changes and legal advice is the main strategy to help to deal with the anticipated changes to the region.
What are the expected impacts of SMP6 on Happisburgh? - Norfolk/Odisha
Over the course of SMP6, it is expected that a caravan park, 35 properties and a church will be lost during the 100 year plan.
