physical fieldwork key hypothesis
The decisions made about coastal management in Start Bay are appropriate
pfwk sub-hypothesis 1
The size of the beach is bigger in the North
pfwk key concept 1
Longshore drift directs sediment to the North, there’s SE prevailing wind (seen from windrose), wave refraction
pfwk method and data presentation 1
beach profile shown in collection of line graphs
pfwk interpretation of data and whether proven 1
The data shows as you go further north, the gradient gradually gets flatter disproving the original hypothesis
pfwk evaluation 1
As you move further north, the beach becomes flatter and wider, unexpected due to longshore drift
However, there could be other processes changing the beach like storms (could have made the north smaller than expected), beach replenishment in the south (explains why the south is bigger than expected)
pfwk sub-hypothesis 2
The risk of flooding and erosion is highest in the South
pfwk key concept 2
The amount of risk is increased by the population present and the value of the properties that could be damaged therefore we need Zoopla to determine the prices
pfwk method and data presentation 2
Flood risk survey shown in a table
pfwk data interpretation and whether proven 2
all areas had a low flood risk showing that good decisions had been made
all areas received between the range of 2 to -6 out of 45 therefore proving the original hypothesis
pfwk evaluation 2
the zoopla prices are more estimated values so it’s not as accurate, we don’t know the value of anything inside the houses
pfwk sub-hypothesis 3
The most effective forms of coastal managements were where you had sea walls, rip rap (rock armour) and beach replenishment
pfwk key concept 3
using geology maps, we can investigate the source of different rock types and investigate whether they’re eroded easily and therefore if hard or soft forms of coastal management is needed
pfwk method and data presentation 3
cost benefit analysis shown in a table
bipolar evaluation shown in a radar chart
pfwk data interpretation and whether proven 3
the data showed that the benefits in Beesands (3.12), Torcross (2.19) and Sunnydale (17.1) outweighed the costs and ergo proving the original hypothesis
The radar chart shows the coastal management in the areas were highly effective against flooding with low construction costs but high maintenance costs, also proving the hypothesis
pfwk evaluation 3
They are good strategies but considering they cost a lot and not a lot of people live there, it’s not considered to be as important
