How have groynes affected longshore drift at Hunstanton
Justification of Physical Question
We know from classwork that groynes are designed to trap material which is transported by longshore drift. This is because groynes are built at 90° to the beach, working against the natural process. As the prevailing wind causes the swash to approach the beach at an angle, the sediment is carried with it. Once the sediment hits the groyne, it can travel no further and is then deposited. Over time this material accumulates, causing the width of the beach to increase. This should also cause the beach to be higher on one side of the groyne

How was the Beach Height at groynes test done
Why was the Beach Height at groynes test done
It will be measured to look at the longer-term trends in LSD at Hunsanton and how groynes work against the natural processes of longshore drift. We hope to demonstrate that the sediment is built upon the side from which the prevailing wind approaches it.

What were the improvement for the Beach Height at groynes test
How was the Beach Width test done
Why was the Beach Width test done
We wanted to see how the groynes had affected LSD. We did this in an area without groynes and we expected a narrower beach because a lack of groynes would mean that there was nothing to interrupt the transportation of material down coast. We repeated this at an area with groynes and hoped to see the groynes trap sediment and therefore make a wider beach, therefore showing how groynes affect LSD

How was the data for the Beach Height at groynes presented
Bar graph (3 separte graohs to represnt the average of top, middle and bottom of groynes)
Why was bar graphs chosen to represent the data for the Beach height at groynes done
So the data from the north and south side of the groynes could be easily compared. A mean was calculated to remove any anomalies and the 4 graphs side by side showed the overall trend for groyne hieght data at New Hunstanton
What were the limitations of the data presentation method for beach height at groynes
The data was based on the average of the top, middle and bottom of the 3 groynes and therefore the bars maybe misleading and could be skewed by any anomalies in the data. This may mean one of the bars is either higher or lower than it should appear
How was the data presented for the Beach Width test
Located proportional symbols. For our 6 locations along the coast, locate a bar at each place to represent the width of the beach. Use squared paper
Why was the data presented the way it was for the beach width test
We want to visually see how the width of the beach varies across the coast. We expect that the beach will be wider in the area that has groynes
What are the limitations for the data presentation for the Beach width test
The only slight negative was the scale we had ti use beause we had a wide range of data. Therefore, knowing the exact beach width without measure the line was difficult
