Beach Profile
21. Methodology
Identify 3 sampling sites across the width of the beach to measure your beach profiles – Mark these clearly on your map
For each Site:-
• Place a Ranging Pole at A (as close to the low-tide mark as safe)
• Identify the key points where the slope angle seems to change (eg. Diagram A below) – use each of these points to divide
your profile into sections
• Measure the distance between point A and B using a measuring tape (Record this in the tables on the next page)
• Measure the slope angle between point A and B using a clinometer (Record this in the tables on the next page)
• Repeat this process for Sections B-C, C-D, etc

24. Methodology Updrift Downdrift
1. Identify a sample of 5-10
groynes and mark these
on your map
2. As close to the low water Wave Direction
mark as is safe use a Diagram C
metre rule to measure the exposed height of the groyne
updrift (direction waves are coming from) – See Diagram B
and C – Record this in the table on the next page
3. Repeat the same exercise downdrift of the groyne

Height of Exposed Groyne
27. For your safety:
• Remain in groups of 2 or 3
at all times
• Obey all signs in the area
• Do not go into the water
No using the or climb on cliffs
ferry!
In your group, you need to:
• Conduct 4 Beach Profiles
• Complete 10 Groyne
height measurements
• Complete pebble sampling
• Complete land use
mapping
• Map sea defences
Limit of activity • Conduct questionnaires
• Create field sketches and
maps
• Take photographs of
evidence of coastal
processes, existing sea
PC= Toilets defences, land uses,
economic activity, habitats
• Make notes on the area
• Complete any extra data
collection
• Make notes on any
