Describe how you PRESENTED and ANALYSED the results of your fieldwork
and research into the effects of coastal management.
Porlock and Minehead SW Somerset
Calculating flood risk by multiplying likelihood (height above sea level by using a
portable GPS device) by severity (value of buildings). These results could be plotted
on GE graph software, as colour gradients represent likelihood and height
A bipolar evaluation of defences from -3 to 3 can be plotted on a graph, either
above or below the X axis depending on whether they are positive or negative.
Questionnaires provide quantitative data which could be graphed up and means,
medians and modes could be calculated. Qualitative opinions of key stakeholders
could be typed into wordle.com (a word cloud of key words/phrases) to be
Digital photos of land uses and features can be annotated.
The beach profile can be three dimensionally mapped to reveal areas of weakness
to flooding and erosion this can show cross sections, from which the volume of
sediment could be calculated.
Cost benefit analysis was used at Minehead we used a land use survey (goad
map) to find out the value of the land being protected. We used this information by
putting it into a cost-benefit ratio our ratio came to 2.08, therefore the benefits
outweighed the costs.
Information from local newspapers e.g. the West Somerset gazette and local
government websites e.g. www.westsomersetonline.gov.uk can be analysed by
wordle.com for common problems.
Websites such as www.Where'sthepath.co.uk can provide old and new map
archives which can then be used to compare and analyse rates of erosion, land uses
and contour lines to show areas susceptible to flooding over time.
Flood maps e.g. on www.climatechangewales.org.uk can be used to analyse the
prediction of flooding in specific areas after a particular rise of sea level.
