Case Study - Hastings Coastal Management.

Extracts from this document...

Introduction

Case Study - Hastings Coastal Management Hastings is a town on the south coast of England approximately 60 miles south of London (see map below). In recent years, the coastline at Hastings has had to face many large scale problems, including the 10 km stretch from Hastings eastwards to the small town of Fairlight. With the coastline at constant exposure to the English Channel, there are many coastal processes which take place along the stretch of beach and cliff. The map on the left illustrates the location of Hastings and also the area of the coastline which is being discussed in this case study. ...read more.

Middle

To do so, various stages of protection work were carried out. The first of these was the main protection of the cliff face; the aim was to prevent any falling rock and also cliff retreat with the hope that this would affect the input sediment rate, slowing it down. An extremely important coastal work implemented at the cliff sites from Hastings eastwards towards Fairlight. It was important however, to implement such works on the cliffs, because of their composition or geology that being soft sandstone with a shingle base all along the coastline. This rock type could prove dangerous, being soft and with little solidness in its structure. ...read more.

Conclusion

As the waves approach the shore, the groynes act as a slowing barrier, sustaining the energy from the waves as they come into collision. The calm water has little energy and so deposits material on the lee of the groynes helping to build up the beach sediment in between the groynes. Fairly effective at helping the beach nourishment scheme, but they do need replacing after several years or even months, and they can be expensive depending upon their size and distance stretching into the sea. The third development has been a huge success. Built around 1896, the harbour in Hastings created a perfect environment for beach nourishment. Longshore drift was the main contributor to the nourishment process, as the harbour trapped the sediment as it moved easterly by longshore drift. AS Geography Self Study ...read more.
