How and Why is Sheringham Protected from the Sea?

Extracts from this document...

Introduction

How and Why is Sheringham Protected from the Sea? The settlements of Sheringham, Cromer, Overstrand, Trimingham, Mundesley, Bacton, Walcott and Happisburgh all sit atop the cliffs, as does the Natural Gas Terminal at Bacton. Together these developments include a huge number of properties and associated infrastructure that would be destroyed if natural cliff retreat were allowed to continue. To avoid the major financial and social implications of these losses, defences have been constructed to limit coastal erosion and protect coastal developments. Sheringham is on the east coast of England in North Norfolk. Sheringham is a town in North Norfolk; its service is tourist resort. It uses many services to attract the tourists to Sheringham such as a historical train station, a boat museum and a special cheese shop. These on average attract about 4500 visitors a year to add to the 7296 people last known living there in 1991. As well as the tourist shops Sheringham is also full of many services for the local people including solicitors and a hardware store. Pie Charts of the service shops and tourist attractions: Although the pie charts show something about the services and tourist attractions in Sheringham, there were a few faults in the collecting of data. One fault was that because the information gathering was done in groups there may be more of the service written down because two groups may have written down the same shop or service. Also the whole of Sheringham was not covered in the exercise so there may be some small shops missing from the data. In conclusion there were many of both types of services, but overall there were much more of the local services than the tourist shops and attractions. Also there was a surprising amount of variety of needed services like grocery stores which means there is quite a large sphere of influence which means that Sheringham is used by all the outlying villages for its food and services. ...read more.

So whilst at the western end of the frontage the beach has not suffered quite so badly, the beaches in front of the Central and East Promenades have been stripped of shingle. This means that the sea walls are in drastic need of repair. The latest scheme to protect Sheringham is called Coast Protection Scheme 902 and consists of two stages and monitoring. The first stage was the repair and renovation of 900 metres of the existing sea walls and the placing of large rock armour stone in front of them to act as buttresses and to absorb the energy of breaking waves. A weak bridge across the fishermen's slipway on the west beach was also renewed. The second stage was the work on the groyne system. All five of the old timber groynes at the west end from the Lifeboat Station to the Admiralty Slip were renewed or replace with new timber groynes and an extra groyne was built. The five remaining timber and steel groynes from the Admiralty Slip to the east end were removed and replaced with four new rock armour groynes. Additionally, 100 metres of the toe of the seawall on the east fisherman's beach was re-enforced and 90 metres of rock armour placed to the west of the Admiralty slip towards the Upcher groyne. As access was very poor and because large volumes of rock were required, it was planned to have the rock delivered by sea directly to the beaches. The cost of stage 2 was approximately �1.85 million and work was completed in 1999. An integral part of the second stage was to monitor very carefully, over a number of years and within a predetermined monitoring programme, just how the existing beach and the sediment moving through the system responded to the new groyne design. It is also necessary to record how the rock armour and the refurbished sea-walls withstand storm surge conditions. ...read more.
