12. 12. Hengistbury Head map 3: Coastal management techniques
13. 13. MethodologyIdentify 3 sampling sites across the width of the beach to measure your beach profiles – Mark these clearly on your mapFor 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
14. 14. Methodology Updrift Downdrift1. Identify a sample of 5-10 groynes and mark these on your map2. 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 page3. Repeat the same exercise downdrift of the groyne Diagram B Height of Exposed Groyne
