Geography Coastal Erosion - Tides and Storm Surges

Extracts from this document...

Introduction

´╗┐Tides and Storm Surges What are tides? Tides are the periodic rise and fall in the level of the sea. What causes tides? How do they work? Tides are caused by the gravitational pull of the sun and moon, the moon influences the move of tides more as it is nearer. The water is pulled towards the moon this creates a high tide, on the opposite side of the earth there is a compensatory bulge. The tide is the lowest in the areas between the two bulges. The high tides follow the moon as it orbits the earth; there is a high tide every 12 hours and 25 minutes (twice a day). ...read more.

What are storm surges and why do they happen? Storm surges are rapid rises in sea level when water piles up against the coast line.. When a tropical cyclone moves across or near the coast, it can cause sea levels to rise higher than the normal tide levels it is the result of the strong onshore winds and/or reduced atmospheric pressure. Storm surge may also be formed by intense low pressure systems. They are a major natural hazard especially in densely populated areas, they can cause damaged property, disruption and in even death. ...read more.

Conclusion

fetch from the north combined with strong winds produce storm waves that were over 6m high There was high spring tides and river discharge into the sea at flood levels. What Happened? In England: Sea defences were breached in several places Thousands of hectares of low lying land was flooded Damage to property Communications and agriculture was disrupted Live stock losses Over 250 people were drowned In the Netherlands: The dyke system which protects huge areas of land was breached 1,800 lost their lives 10% of the countries agricultural was lost Response To prevent any future devastation by storm surges the themes barrier and the dutch delta schemes have been built ...read more.

    Plants retain sediment in wetlands and impede movement of coastal dunes. Natural processes that change the water level also affect coastal dynamics. Taken individually, each natural process of coastal transport is complex; taken collectively, they create an extraordinarily intricate system that attempts to achieve a dynamic balance.
