Crowded coasts Flashcards
Use of current and historical maps - RESEARCH
Description
- www.britishhistory.co.uk
- Compare maps and coastlines of Mappleton over 1910-1988
- Roman times map to view coastal erosion
Use of current and historical maps - RESEARCH
Explanation & Justification
- Allow us to compare strategies and success of different coastal management schemes by calculating erosion rates over time.
- J/ Time efficient as it allows us to make a quick and easy judgement of relative success of coastal defences.
Use of current and historical maps - RESEARCH
limitations
- The resolution of the maps didn’t allow us to calculate accurate rate of erosion
- Heavily relied on interpretation of data as no explanation was given/ Could have used other aerial photos so less interpretation.
- Assumed that erosion was always constant and never triggered by one off events.
- Unaware of exact land and value of land lost
Use of historical photos
Description
- ‘Cliff farm’ website provides photos of Ulromes over the last 40 years.
- Accessed various photos from ‘Geograph’ website
Use of historical photos
explanation & Justification
- Able to identify the correlation between the publication date of photo and erosion at site
- Photos had a higher resolution and hence less interpretation required & more straight forward.
- Freely available and large areas can be studied with ease
- Comparison over time and how management has an impact on the area.
- Displays which land is lost and what type of land it is
Use of historical photos
Limitations
- Quality of historical photos is not as good as now
- Photos are only available over a limited time period and inconsistently over the years
- Lots of gaps in timescale
- location of photos is scattered around the area cannot see period developing over time
Use of archived articles (internet / newspaper)
Description
Accessed newspaper articles on coastal erosion about events in the area on google news
Use of archived articles (internet / newspaper)
Explanation/ justification
- We accessed the news stories to record major events which contributed to coastal erosion as large scale would be recorded
- Less need for interpretation of data and more accurate diagnosis of an outlier in the rate of erosion if we were using maps and photos
Use of archived articles (internet/newspaper)
Limitations
- Very few news stories available on the hodlerness coast hence uncertainty about lack of events occurisng or lack of events being recorded
- Limited news articles will be stored on the internet
- Local newspapers will be biased / downscale it
Use of shoreline management plans
Description
We accessed the Holderness SNP to find out which areas were deemed high value ( hold the line) and those which were low value ( no shit all)
Use of shoreline management plans
Explanation & Description
- We wanted to determine which areas were actively being protected by the local council and those being less prioritised
- This gave us an idea of how valuable the land was and why the council prioritised
- it as well the defence mechanisms implemented and how successful they were in each area.
Use of shoreline management plans
Limitations
- We could only speculate about the effectiveness of the coastal defences as no quantitative data was provided.
- Use SMP and collate it with our own primary data to gauge a correlation
Use of GIS
Description
Accessed historical and aerial photos from the GIS, looking at management strategies such as sea walls
- Hull university website current satellite maps, previous and even predicts future satellite coast lines
Use of GIS
Justification/ explanation
- time efficient/ easy
- Reliable source
- Help us calculate future issues that may be caused due to coastal erosion
Use of GIS
Limitation
Limited photos as only 3 over 5 year time span and none afterwards
Cannot predict sudden storm surges ect which influence future coastline as it assumes consistent erosion rates
