groyne drop

upside down bar chart - x groyne number y drop to the beach cm, two bars for each groyne N and S, blue and red

groyne drop pros

visually effecrive due to reverse, maps out shape of beach, colors make it easier to read, clear pattern very obvious - larger drop on North side

disadvantage groyne drop

as there is a large scale up to 160cm, the exact values are difficult to read

beach profile cross sectional area vs distance along beach

scattergraph with line of best fit. x - distance along beach m y- cross sectional area m squared.

beach profile pros

line of best fit shows as distance along beach increases, cross sectional area decreases. it is visually effective as a gradient along beach.

beach profile cross sectional area vs distance along beach

difficult to read exact distance along beach due to large 500m interval, points are very random, last one very anomolous 2000m along 140 m squared when should have the smallest area, suggests we should have kept going along the beach.

annotated photos cons

can be subjective, can contain too much information and depth of judgement difficult.
