Beach Profile
Hengistbury Head map 3: Coastal management techniques
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
Diagram A
Methodology1. Identify a sample of 5-10
groynes and mark these
on your map
2. As close to the low water
mark as is safe use a
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

PC= Toilets
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
or climb on cliffs
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• Conduct questionnaires• Create field sketches and
maps• Take photographs of
evidence of coastal processes, existing sea defences, land uses, economic activity, habitats
• Make notes on the area• Complete any extra data
collection• Make notes on any
problems and limitations of your data collection
