Coasts 1 - Planning Flashcards
Name the stretch of coastline we studied
Start Bay
Which of the following settlements is not on the coast
Slapton, Torcross, Beesands, North Hallsands
Slapton - Slapton is a village 1/2 mile inland.
What was the name of the road than ran along Slapton Sands?
The A379
Explain one reason we chose to study the Start Bay coastline
There are a range of different techniques used to manage erosion and flooding along a relatively small area, so it’s easy to investigate the contrasting impacts of coastal defences on people and communities
Arrange these coastal settlements from south to north
Torcross, North Hallsands, Sunnydale, Beesands
North Hallsands is furthest south, then Beesands, then Sunnydale with Torcross furthest north
What was out coast enquiry question?
Do the benefits of coastal management will outweigh the costs within Start Bay?
Suggest two factors we considered when choosing the fieldwork locations?
Accessibility - all the sites were easily accessible from the coastal path and were close enough together to be covered in a day
Start Bay is an area that has suffered from the impact of severe storms in the past. Therefore it’s a good place to investigate the benefits of coastal defences.
Why was hard engineering deemed inappropriate along Slapton Sands?
Because of the presence of the Slapton Ley National Nature Reserve which includes the shingle ridge (bar) and lagoon behind.
Which wind direction most often results in destructive waves forming in Start Bay
East (i.e. winds that blow from the east to the west)
What process moves material from south to north along the beaches of Start Bay?
Longshore drift.
Why is climate change likely to increase the need for coastal management in the future?
Sea levels are likely to rise and storms are likely to become more severe and more frequent, leading to more destructive waves removing beach material.
What physical geographical processes and concepts relate to our investigation?
Longshore drift Sea level rise Marine transgression Sediment cells Erosion Wave refraction Fetch
What coastal management concepts relate to our investigation?
Cost-benefit analysis
Hold the line/managed retreat/do nothing.
Tell me an alternative enquiry question that might be appropriate to investigate at the coastline
Your own answer here!
You could say:
How does beach sediment change from north to south along x beach?
How and why is coastal erosion presenting a greater problem in some locations along Start Bay than others?
How did we use newspaper articles as a source of secondary data in planning our investigation?
The newspaper articles helped us see that coastal erosion and flooding were issues that needed to be managed along Start Bay as settlements such as Torcross and Hallsands had been affected in the past.
Knowing this helped us come up with a suitable enquiry question / hypothesis to focus on.
How did we use a map as source of secondary data when planning our investigation?
The Ordnance Survey map of Start Bay helped us by:
Showing that we could access virtually the whole coastline from the south-west coastal path. This gave us freedom when choosing sites to collect data.
Making it clear that all the significant settlements (e.g. Torcross and Beesands) were in the south of the bay so therefore it made sense to collect most of our data from the south rather than the north of the bay.
Helping us see where various see defences were built so we knew where to collect our data.
Helped us make sense of how Start Point caused wave refraction
What other secondary data might have been useful to have when planning your investigation
A shoreline management plan (SMP) showing the approach to coastal management in different locations along Start Bay, i.e. where ‘hold the line’, ‘do nothing’ or ‘managed realignment’ was being used.
What does a rose diagram show us?
Prevailing wind direction
Mainly from the South West
On a stormy way - from the North East
What caused Slapton Sands to form in the first place?
Marine transgression / sea-level rise -
4,000 years ago
What is the most important process operating on Slapton Sands today?
Probably longshore drift (from South to North)
How do we know storms caused problems in 2017
Photos of the A379 show the road destroyed by strong waves.
It’s been rebuilt since…
