The Thames Barrier spans 520 metres across the River Thames near Woolwich, and it protects 125 square kilometres of central London from flooding caused by tidal surges. The barrier is closed under storm surge conditions to protect London from flooding from the sea.

Why was Thames Barrier built?

The barrier, built in 1982 on the Thames on the eastern side of the capital at Woolwich, was designed to protect 48 sq miles (125 sq km) of central London from flooding caused by tidal surges.

When was Thames Barrier opened?

1984
The Thames Barrier/Opened

Construction began in 1974. The barrier was finished by 1982 and first used in 1983. It was officially opened by the Queen in 1984. The Thames Barrier is the second largest flood defence barrier in the world.

How long will Thames Barrier last?

This defence level allowed for long-term changes in sea and land levels as understood at that time (c. 1970). Despite global warming and a consequently greater predicted rate of sea level rise, recent analysis extended the working life of the barrier until around 2060–2070.

How do the Thames barriers work?

The Thames Barrier is made up of ten steel gates and spans the entire width of the River Thames. The gates control the amount of water allowed to flow from the North Sea into the Thames. When the gates are in the open position, the Thames flows freely and ships can pass through.

How old is the Thames Barrier?

37c. 1984

Does London ever flood?

It was the last major flood to affect central London, and, along with the disastrous North Sea flood of 1953, helped lead to the implementation of new flood control measures that culminated in the construction of the Thames Barrier in the 1970s.

What is the largest flood barrier in the world?

the Oosterscheldekering
The Delta Works in the Netherlands is the largest flood protection project in the world. This project consists of a number of surge barriers, the Oosterscheldekering being the largest surge barrier in the world, 9 kilometres (5.6 mi) long.

How fast is London sinking?

04 inches per year — while the south of the UK is sinking back into the sea. Although the metallic gates of the Thames Barrier were designed by engineers to protect London against flooding, they were only expected to be needed a maximum of three times per year. Currently, they’re being used six or seven times per year.
