Introduction North Norfolk has one of the most beautiful and unspoilt coastlines in England. Natural physical processes have caused a remarkable series of ever changing sand flats, shingle ridges, spits and dunes. Areas totally enclosed from the sea have become fresh water marshes and grazing land, while others remain as brackish marshes and saltings. Cley-Next-the-Sea is at the start of Blakeney Point, a composite shingle spit 3.5 miles long, stretching west. Behind the spit, a number of habitats have been created. Norfolk Wildlife Trust Cley Marshes is a freshwater marsh, nowadays a very rare habitat. Flooding by sea water can destroy this fragile freshwater marsh. Many different coastal processes are at work on the Norfolk coast. Long shore drift is a process that carries the shingle on the beaches in the direction of the prevailing wind which happens to be west, and deposits it to create the spit. ...read more.

Middle

There was an increase in mud as we moved further away from the sea, but it soon decreased as we approached the shingle beach again, as shingle gradually increased. Longshore Drift measurements The graph drawn, represents the distances travelled by each dog biscuit, shows that at times, the waves were quite powerful and strong - such as the waves that were counted for dog biscuit no.7 as it travelled the furthest distance of 110m. But some waves were not as powerful such as the case of biscuit no.5 which only managed to travel 7.5m. Data Interpretation Beach profiles The two beach profiles show a clear difference in the shape of the two beaches. The managed beach is much higher than the unmanaged beach, which is rather flat. This is because the managed beach is artificially maintained, and it needs to have a higher shingle ridge so that the freshwater marsh is protected. It is the current coastal protection method that is being used to protect the freshwater marsh. If this method was not used, and the coastal processes were left to work naturally without any artificial maintenance by humans, the shape of the beach would look more like the current unmanaged beach does. The photographs that were taken of the two beaches also show a clear difference in the height and shape of the two beaches. Sediment Analysis The sediment size analysis graphs show that on the managed beach, there seemed to be an unspecific pattern in sediment size as we moved up the beach. The graphs show that there were larger pebbles towards the bottom of the beach, near the sea, but the amount of pebbles between 1cm and 1.9 cm varied across the whole beach. Ridge 4 - which is the main shingle ridge that is steep, to protect the marsh - contains rather small pebbles, mostly below 1.9cm. I expected there to be much larger pebbles in this area because this is where the new artificial pebbles will be placed so they will not have been eroded by sea water. ...read more.

Conclusion

The beach profile data we took were extremely useful and very accurate as they helped us to draw accurate beach profiles. The method we used to measure sediment size however was not as good because it only allowed us to measure the b-axis of each pebble. A more accurate method would have been to measure the perimeter of each pebble, instead of the b-axis because it would show us the overall size of each pebble instead of just a width. We estimated sediment shape by using "Power's Scale of Roundness". This was quite a good method because there was only really this way to measure sediment shape. I think we should have investigated the salt marsh a little further. A possible way to investigate further would be to possibly measure the pH of the soil every 5m to see whether it changes as we move further inland. This might have given us a more distinct pattern for the plant species survey. Appendix If the bank is not built, the shingle beach will continue to be artificially maintained each year, which in the long term is a more expensive method. Another bad storm surge will probably cause a sever flood into the local towns, and at the same time destroying many habitats in the freshwater marsh. The wildlife will suffer and their homes will be destroyed. Norfolk Wildlife Trust will lose money every time this happens because tourism will decrease if there is no wildlife around and it would cost money to help fix the mess caused by the flooding. If the freshwater marsh was left to return to salt water marsh, the area would lose out on tourism and the Norfolk Wildlife Trust would be at a disadvantage because the area would no longer be a tourist attraction. Therefore no more money would be made and this countries economy will lose money. Not only is this area a useful source of money, it is home to many different plant and animal species. Letting the marsh turn back to saltwater would destroy these rare plant and animal habitats, which is very un-environmentally friendly. ...read more.
