23. 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

26. 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

28. Pebble measurement:
The simplest way to measure pebble shape is to classify the stone as
very angular, angular, sub-angular, sub-rounded, rounded or very rounded.
Decide which shape is the best fit for each pebble.
For an estimate of pebble size, measure the longest (a) axis of each pebble.
You should aim for at least 20 pebble measurements from a minimum of three sites.
A larger data sample will improve the quality of your investigation, consider your time
management in order to achieve this.
