The document provides instructions for a field trip to Hengistbury Head to study coastal geomorphic processes. Students are to: 1. Meet at 7am by the minibuses, bring lunch and money. 2. Conduct beach profiles and groyne height measurements at sampling sites, using equipment like ranging poles, measuring tapes, and clinometers. 3. Complete additional tasks like pebble sampling, land use mapping, questionnaires, photographs, and notes on coastal processes, defences, and limitations. 4. Meet at the café drop off point at various times and their beach survey slot is to be determined.

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

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
