Geography Field Trip to Cuckmere Haven to study Erosion

Geography Field Trip to Cuckmere Haven to study Erosion Data Analysis Pebble Sizes The pebble size graph shows the pebble heights of the three profiles. The pebble sizes should tell us that the closer the pebbles are to the water the more it is eroded therefore the smaller it is. The graph shows one profile with a straight line one getting smaller as it goes away from the beach and one getting bigger as it goes further from the beach. Only profile number two looks to be accurate number one and number three are unreliable. This result is the only anomaly so far where it acts against the hypothesis by having three different findings. Wind, Wave Direction The wind and wave direction helps us to predict any long shore drift. The wind direction at the time came from the southeast with a speed of 3.336km/h. This makes the wave direction southwards. The waves came from an angle when they hit the beach. When we put a cork in the water it travelled 30m to southeast. This result shows us that there is a longshore drift moving the beach particles at Cuckmere Haven. According to the book: "The Wider World by David Waugh1994" "Sand and shingle being transported along the coast by longshore drift will, in time, reach an area where the water is sheltered and the waves lack energy, e.g. a bay. The materials will temporarily be deposited to form a beach. ...read more.


If the waves are constructive therefore the amount of waves arrived in a minute should be 6 to 8 and if it is destructive waves the amount of waves should be more than 12 waves. The result shows us that the waves arrived in 5 minutes is 41 waves, which makes the waves arrived in a minute 8.2 waves. Consequently this tells us that the waves are constructive. The hypothesis tells us that the coastline is dominated by deposition. According to the book: "The Wider World by David Waugh1994" Constructive waves have a strong swash, which moves the materials up the beach meaning there is more deposition therefore the result is for the hypothesis. Beach Profile The profiles are about the way in which the waves are eroding and depositing the beach. It can show us where on the beach there has been more erosion and deposition. If the beach profile shows a gentle slope it means the waves are constructive but if the waves are destructive there must be a steep slope. By looking at the beach profile you can see that it shows the cut version of the beach. Each of the measurements was taken from three different positions on the beach. This therefore makes the result quite similar. By looking at the profile all three of the beach profiles start moving upwards gently and then falls slightly down from the last two breaks in the slope. The profile proves to have a gentle slope meaning that the waves are constructive. ...read more.


They provide us with the knowledge of whether the waves are constructive or destructive at the time. Conclusion The hypothesis stated that: "The coastline at Cuckmere Haven is dominated by processes of deposition" This hypothesis is proven to be true with the evidence collected. The data that were for the hypothesis where the evidence of longshore drift. Such evidence was the distance the cork moved across the beach and sketch two where you can see the beach materials are collected on one side of the groynes and is empty on the other side. The wave height, beach profile and the amount of waves arrived in five minutes where also for the hypothesis. This is because it shows that the wave at the time was constructive which meant there was more deposition than erosion. We had no evidence that was to be against the hypothesis. The inconclusive evidence that I found was the data on the pebble sizes. This data was not reliable because the three different data show different results where they had to be similar. In my prediction I said: "The process of deposition will shape the coastline of Cuckmere Haven but not only deposition takes place but erosion has another big affect on the beach and cliffs." My prediction was true both the deposition which was the same as the hypothesis, which I mentioned earlier to be proven true. The prediction of erosion was also true because we saw in sketch two where seawalls were placed to stop erosion of the cliffs and sketch three where we saw wave cut notch and a collapsed cliff. So it is proven that processes of deposition dominate the coastline of Cuckmere Haven. ...read more.
