Introduction

Karl Bowers 11Bu Friday 25th June 2004 Aim 1- Destructive or Constructive enquiry: Aim 1 To test if processes of deposition are stronger than processes of erosion on the beach. The first aim was carried out at site 2 on Deal beach, by the Groynes. This was mainly because we needed the Groynes to assist us in the investigation. The other site could have been suitable as well, but where my group was specifically positioned, the pier was there and that could have interfered with our results. There was a purpose of this particular aim - to discover what was shaping deal beach on the day of our visit. To successfully do this, we had to se if the beach was being destructed by erosion or if it was being constructed by deposition. The only way we could do this way by counting how many waves were producing and breaking per minute on the beach. Theory On the British coastlines, waves are responsible for pretty much all of the erosion. When a wave approaches the coast, it is slowed by friction from the seabed, but the top part of the wave will continue at its constant speed. ...read more.

This is the result of friction between the water and the beach. This causes a wave to break. Deal is very special as it has waves approaching it from two different directions. From the north and from the south. The waves from the south will have a large fetch because they have travelled over the Atlantic Ocean, whereas the waves from the north, will have a smaller fetch because the waves have to travel over the North Sea, which is a much smaller size compared to the Atlantic Ocean. Fieldwork Method The fieldwork experiment we used for the first aim was to determine the frequency of the waves on the day of our visit. We were looking to see if they were constructive or destructive. To do this we had to pick a point out that was fixed so we could count how many waves crashed at that point. For this experiment, we used the Groynes. They were obviously in a fixed stationery position, so they were ideal to use. Every minute, we recorded the number waves, for 10 minutes. ...read more.

Conclusion

Analyse By looking at these results, I can see that there is a clear average between the results because they are all roughly 10 to 12. There is only one anomaly, which is the recording after eight minutes, which are 9 waves. This isn't very important, it may just be where the person counting the waves, missed a wave. Besides that, there is nothing wrong with the results we managed collect Conclusion I can conclude from my results that due to the average number of waves being above 10, the kind of waves hitting Deal beach are destructive. This means that as the waves break on the beach, instead of depositing material, they are in turn, eroding the beach away. Relation to Hypothesis After concluding my results I found out that the waves breaking at Deal Beach are eroding it away, instead of depositing onto it. My hypothesis is 'to see if Deal is being shaped more due to the process of L.D (if we found L.D present on our visit) or by human activity on the beach'. MY results show that deal is being shaped by L.D, rather than human activity, because the waves are destructive, meaning they are eroding the beach. ...read more.
