Physical Fieldwork

What is the physical hypothesis?

The costal management strategies at Hill Head are effective

Why was it a suitable location?

The South Coast is experiencing more costal erosion and Hill Head has a new sea wall and some groynes. It is close to the school so there is more time to collect the data

What are risks of the loacation?

Falling over, drowning

How can these risks be reduced?

Wearing suitable footwork, checking tide times, and avoid collecting data near the sea

Why is a risk assessment important?

To avoid dangerous situations and have a plan to keep people safe

What are the data collection methods?

Environmental quality survey and a groyne drop

What is the type of data collected from the EQS?

Primary, Qualitative, and Systematic

How was the EQS data collected?

Look at the sea walls and groynes and make a judgement using a bi-polar survey on a scale of -3 to +3

Justify this method? (EQS)

It provides an overall score about the sea defences since the variables cover a range of aspects including evidence of erosion, overtopping, aesthetic appeal and safety

What are the strengths of the EQS?

Easy to do, requires equipment, lots of variables measured, and able to compare scores

What are the weaknesses of the method?

Very subjective

What is the type of data collected in a groyne drop?

Primary, quantitative, and systematic

How is the data collected from the GD?

Start at the base of the beach, measure equal intervals along the groyne. Then at those equal intervals, measure the distance from the top to the sediment on both the east and west side.

What are the strengths of the method?

It is easy to complete, simple equipment, quantitative data

What are the weaknesses of GD?

It is difficult to measure on a windy beach, groynes may be damaged or submerged

What are the results of the EQS for groynes?

-3/30

What are the results for the EQS for the sea wall?

9/30

What is the average drop for the east?

36m

What is the average drop for the west?

23m

What is the data presentation for the EQS?

A radar graph

What are positives for the data presentation for the EQS?

Easy to read, visual, can plot and compare variables on one graph

What are negatives for the data presentation for the EQS?

Difficult to draw, data overlaps and it becomes hard to read, too many variable make the graph confusing

How is data presented for the groyne drop?

Bar graph

What are the positives for the way data is presented for the groyne drop?

Visual, easy to read, shows a clear difference, shows the data along the beach

What are the negatives for the way data is presented for the groyne drop?

Better if it is a located bar chart, better if inverted to present the drop
