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

Meet at the café drop off point at 10am, 11:30am, 2pm, 2:30pmOur slot at Beach survey is:

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
