A study of sea defenses along the Lincolnshire coastline after the 1953 floods

Extracts from this document...

Introduction

A study of sea defenses along the Lincolnshire coastline after the 1953 floods For my project I am going to look at sea defences along the Lincolnshire coastline since the 1953 floods. I will look at what defences are currently in place and how, if at all, they have changed since the floods in 1953. I am going to look at the beaches at Huttoft and Sutton on Sea which are located on the Lincolnshire coastline. As I am looking at the sea defences I will not need to collect very much raw data. I will take notes on how the sea defences work and document them in my project. I will need to collect mainly photographs of sea defences that are in place on the two beaches. I will collect these using a digital camera for myself which is primary data and using pictures from other sources e.g. other people in my group and websites that may already have pictures of sea defences which would be secondary data. ...read more.

These are deep hexagonal blocks which have a whole down the inside. They are placed at approximately a 45degree slope so that a wave breaking upon them will enter the holes and the water will swirl around destroying the wave energy. Because of there hexagonal shape they tessellate so many can be placed together along a slope. The 1953 Floods The floods happened at 5:25pm on the 31st of January 1953 after a bad storm surge. There was no flood warning and the sea defences that were currently in place were not good enough to hold back the sea. The floods caused terrible damage with 307 people killed 24,000 houses damaged or destroyed, 150,000 acres of farmland destroyed, which were rendered un-useable for several years afterwards as well as the loss of a lot of livestock. 30,000 people were evacuated and over 200 industrial buildings were destroyed. The overall damage of the floods was estimated at the time to be around �50million. ...read more.

Conclusion

The sea wall is a good sea defence and should stop most waves unless there has been a bad storm surge. Other sea defences include; Groynes: These are long wooden barriers placed down the beach perpendicular to the sea. They slow down longshore drift so that there is more sand on the beach. Longshore drift is where waves push large quantities of sand along the beach which can therefore make certain areas where there is a low amount of sand more susceptible to flooding. Gabions: These are netted wire boxes which contain medium sized hard rocks inside. Revetments: revetments are slatted and angled low wooden walls parallel to the beach. They act to absorb wave energy and protect soft cliffs. The waves break upon it and water can pass through but they destroy most of the energy. These can be susceptible to rapid erosion. Dragons teeth Concrete blocks held together form a powerful sea defence, these are known as dragon's teeth ...read more.

    This is only to exception from 0-2.4 centre metres. The pebbles are distributed evenly around Gore Point because abrasion is always breaking up the rocks to form smaller rocks.
