The Holderness Coast

Extracts from this document...


The Holderness Coast The Holderness coast refers to a section of the East Coast from Flamborough Head to Spurn Point. The total distance of this coastline is 50 kilometres from the North to the South. The rocks in this area consist mainly of softer rocks, such as Chalk, Boulder Clay, Gravel and Sand. This one of the reasons why the coastline is eroding at a very fast rate. The other reason is because of the powerful effect of the artic 'long fetch' where the energy of 3000miles of sea is dispersed onto the coastline. Due to longshore drift, the material is gradually being taken from the North and deposited at the South, at Spurn point. This is the reason why Spurn point was formed, because of long shore drift. There is only around �250,000 to protect the whole of the coastline, which is hardly anything considering the cost of sea defences and the 50km stretch of coastline that this money has to protect. From the fieldwork I did at 3 locations on the Holderness coast; Barmston, Hornsea and Mappleton, hopefully I have sufficient data to produce a report on the Holderness coast's sea defences and see what consequences it has on the Holderness coast. At each of the 3 beaches we did 3 separate tasks 1. A beach profile - Pebble survey, Angles of the beach between different sections. 2. A beach observation map - Drew a map of the area to show the types of land use, sea defences and cliff management. 3. A coastal visions survey - Environmental survey, Bi-polar. Method 1. Beach profile Firstly, 3 sections of the beach are decided upon; North, South, and the central area of the beach. Then each one is visited in turn. A quadrant is thrown, around 5 metres away from the cliff/wall. This is measured by using metre rules. Then where the quadrant is thrown, 5 pebbles are picked up (if possible). ...read more.


These, together, hold the cliff together so that that erosion hardly takes place due to the grass holding the soil in place and the plastic sheets prevent erosion by stopping the water seeping into the ground and becoming loose. Instead all the water runs off on the surface. Conclusion Mappleton as a village isn't really a village that is viable for protection. But due to the road and most probably, the MOD site. The area has been protected. The agricultural land south of Mappleton hasn't had any coastal defences/cliff management money invested into it. The cliff has been graded and rock armoured in areas that are most important. A lot of money has been spent on the Mappleton protection plan, which would not have been spent if it wasn't for the B1242, which is the backbone transport link for this section of the coastline. Without it many settlements would eventually disappear, as people would not be able to get about. The Mappleton sea defences are a solution to a major problem, but in turn this has made the cliffs past the sea defences, much more susceptible to erosion, creating another problem along the Holderness coastline. Task 2 Analysing the Pebbles As we are not geologists, it was hard to determine the rock type at many areas. So the rock type results become insignificant during this report as there isn't enough data. Attrition is a process that occurs at all three beaches Barmston Central At Barmston central, there seemed to be a pattern occurring. The larger rocks/pebbles were found near the cliff, they were also the least rounded of all of the pebbles. The reason for this is that the rocks/pebbles won't have been weathered a lot in comparison to the other stones, and would have fallen off the cliff. The ones nearer to the sea would have been broken down by the action of waves, which make them become rounder. ...read more.


The peaks of the graphs being the ones with the most erosion occurring. The average per year takes into account all the years since the post has been set up. So if sea defences are relatively new, it will only just start lowering the average per year. Where longshore drift is stopped, due to coastal defences (the areas where coastal defences occur, are usually located where there is under 0.5m erosion per year), hardly any coastal erosion occurs. But the areas further south down the coastline, past an area of sea defences (usually the areas with more than 2m of erosion per year), the coastline erodes much higher per year (on average) 6. Which site has lost the most cliff material since the post was originally established, suggest possible reasons why? 'On fence line S. of dyke, N of Cowden'. By the location name, it does not seem that this site has any economical value, thus has not been protected by sea defences until recently. The rock in this area must have been very soft and the sea defences to the North of it has had a drastic effect on it over a long period of time. It has lost 142.56 metres of cliff since it was established. 7. which site has experienced the highest average erosion rate per year during the total period, suggest possible reasons why? I am taking the 'total period' to be since 1951, so any posts not setup in that year, then the data will not be deemed relevant. Since 1951, 'On fence line S. of South Cliff, Hornsea' is where the highest average erosion rate per year occurs. A likely reason for this is a very similar reason to the answer of question 6. The rock in this area is very soft and the sea defences to the North would have been established a long amount of time, having a massive impact on erosion. This area seems to be the most likely place where the waves have the most energy throughout the whole Holderness coastline. ...read more.

    A monitoring system was also set up to detect movements in the cliff. In the 1980s the coastal management schemes at Bishopstone Glen were extended. As there is a protected area, S.S.S.I. (Site of Special Scientific Interest), a less discordant approach was needed.

    Waves move within the sea but cannot disperse their energy - rather like water slopping up against the side of a washbasin. Lastly the sea floor is deep along the coast. Therefore, the waves reach the cliffs without first being weakened by friction with shallow beaches.
