Coasts - Case Studies Flashcards
What case study illustrates concordant and discordant coastlines?
Isle of Purbeck, Dorset (UK) - aka. Jurassic Coast
What case study shows Dalmatian and Haff type concordant coasts?
Croatia (Dalmatian) and Baltic Sea (Haff)
What case study demonstrates how geology affects erosion rates and cliff profiles?
Dorset (UK)
Which area shows rapid coastal recession due to physical and human factors?
Holderness Coast (UK)
What coastline is affected by coastal flooding and sea level rise in a developing country?
Bangladesh
Which event is a good example of storm surge and climate risk?
Cyclone Sidr (Bangladesh, 2007)
Which island nation illustrates environmental refugees due to climate change?
Kiribati
What case study shows soft engineering and managed realignment?
Abbotts Hall Farm (UK)
What areas (2) uses ICZM and SMPs to manage the coast?
Holderness SMP and UK Sediment Cell 2
Medmerry
Where does sustainable management cause conflicts?
Bangladesh and the Maldives
What are the characteristics of the Isle of Purbeck’s coastline in Dorset, UK?
Discordant along the east has alternating bands of geology resistance perpendicular to the sea (Swanage bay + Durlston head)
Concordant along the south - has parallel strata of Jurassic rocks (Lulworth cove)
What geological features characterize the Dalmatian coast of Croatia?
The Dalmatian coast is a concordant coastline formed by tectonic compression during the Alpine Orogeny, which created parallel anticlines and synclines.
Rising sea levels flooded the synclines, leaving the anticlines as elongated islands parallel to the coast
What factors contribute to the rapid erosion of the Holderness Coast in the UK?
The Holderness Coast experiences erosion rates averaging around 2 meters per year, primarily due to its soft boulder clay composition, which is highly susceptible to erosion.
This has led to the loss of approximately 5 kilometers of land since Roman times, including 23 towns and villages.
What are the impacts so far of the Holderness erosion
The loss of approximately 5 kilometres of land since Roman times, including 23 towns and villages.
When did Cyclone Sidr strike Bangladesh?
November 15, 2007
What were the wind speeds of Cyclone Sidr (mph)
160 mph
What was the estimated and minimum death tolls of cyclone Sidr?
Estimated death tolls reaching up to 15000
At least 3447 deaths
How is Kiribati affected by sea level rise?
Kiribati’s 33 islands are highly vulnerable to sea level rise, with many areas just a few meters above sea level.
Rising seas threaten to submerge land, increase storm surge impacts, and displace populations, potentially creating environmental refugees.
What is the managed realignment project at Abbotts Hall Farm in Essex?
Initiated in 2002, the Abbotts Hall Farm project involved breaching sea walls to allow 120 acres of farmland to flood, creating new salt marshes.
This approach provides sustainable coastal defence and valuable wildlife habitats.
What are the key features of the Shoreline Management Plan (SMP) for the Holderness Coast?
The SMP for the Holderness Coast divides the area into sections based on coastal processes and shoreline characteristics, aiming to manage erosion and flood risks effectively.
What challenges does the Maldives face regarding coastal management?
The Maldives is threatened by rising sea levels, which pose significant risks to its low-lying islands.
Coastal development has exacerbated environmental issues, necessitating integrated coastal zone management strategies to mitigate impacts.
What role does dredging play in managing the Nile Delta’s coastline?
Sediment Supply: Dredging is used to deepen the river channels and ensure the flow of water, helping to transport sediment to the delta.
Flood Control:
