The Thames Barrier
Saving London from flooding
a) The North Sea floods of 1953 were one of the worst natural disasters to affect the UK.
A combination of storms and high tides caused sea levels to rise over three metres above normal levels. Three hundred people died and the flooding damaged 1,600 kilometres of coastline and 24,000 properties.
b) The River Thames has flooded many times in the past, causing damage and death. But if London flooded today, it would be difficult to calculate the cost of the damage. Many of the capitaltasks iconic sights on the banks of the river would be destroyed, transport systems would break down and millions of lives would be affected. This is why engineers have spent a lot of time and money on projects to prevent London flooding. The most important is the Thames Barrier.
c) The Thames Barrier crosses the river at Woolwich in the south-east of London. Four thousand people worked on the project, which cost 500 million pounds to build and officially opened in 1984. The Thames Barrier stretches from one bank of the river to the other - a distance of 520 metres. It is the second biggest movable barrier in the world -after one in the Netherlands. The barrier has nine concrete piers dividing the river into ten channels. At the end of each pier there are large gates which are normally open. If there is a flood threat, the gates will close, shutting off the river within 30 minutes. Since the Thames Barrier opened, it has been used more than 100 times.
d) Engineers believe that the Thames Barrier will protect London from the worst effects of flooding until 2030. However, environmentalists believe that a combination of the increase in sea levels as a result of the melting of the ice caps and more frequent storms caused by climate change will increase the risk of flooding. If things dontaskt change soon, the barrier will not protect London for long.
