Aims and uses of ICT and evaluation

Aim: to investigate the differences between protected and unprotected stretches of coastline

uses of ICT

  • maps
  • research prior to investigation
  • images
  • tide time tables
  • data presentation


  • 4 areas of the coastline used for transect
  • all along one strech of coastline so less likely to have anomolous results
  • 9 different readings for the vegetation
  • 10 readings done for the cliff angles

evalutaion and criticisms

  • stood at some distance from cliff for the quadrat
  • all started in the same place for the beach transect
  • 3 pebbles taken from each area


  • places of transects 3 in an area of protected coastline, 1 in an area of unprotected coastline
  • paces unreliable soucre of measure for distance
  • approximation used for the quadrat and cliff angle
  • no compass used
  • field sketches could have involved a cross profile/section being drawn
  • some areas were restricted by water-pools and runnels etc
  • only on one stretch of coast so results couldn't be vaired with another stretch
  • there wasn't a distance measured from the cliff when doing the cliff angles which could have affected the results

Hyp 1 and Hyp 2


  • More erosion at unprotected than protected
  • Proven
  • Done by field sketh of area which shows differences in vegetation, beach slant, cliff retreat etc


  • More vegetation at protected than unprotected
  • Proven
  • 9 readings of each area, equidistant from cliff
  • avearage found and put into a piechart
  • used a kite diagram to show range between the 2 areas
  • this is due to more impact of subaerial weathering

Hyp 3 and 4


  • steeper cliff angles on protected than unprotected
  • disproven
  • used mean, median and IQR only showed a larger spread for unportected but didn't clarify much of difference in steepness
  • used box and whisker diagrams
  • 10 readings taken randomly on the cliff at 2 differnet areas (5 per area)


  • protected beaches are more sloped than unprotected
  • wider range and more sloping for protected, unportected was more gentle, less sloping and smaller range in angles
  • used a clinometre in 4 different areas
  • proven
  • showed by using a transect graph

Hyp 5


  • Nul hypothesis: no correlation between sediment size and distance from cliff
  • proven
  • measured 3 pebbles every 5 paces, average was taken
  • Used spearmas rank which showed 0.1 correlation therefore no correlation
  • checked against conidence levels
  • plotted on a scatter graph

Health and saftey risks

  • Rock fall from cliffs
  • drowning
  • entering deep water to measure
  • slipping off rocks or groyne
