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.
What would happen to London without the Thames Barrier?
Without the barrier the Houses of Parliament, the O2 arena, Tower Bridge and areas of Southwark, Beckton, West Ham, Whitechapel would all be submerged in flood water.

It sees nearly all of land in around Canary Wharf, the Royal Docks and the Greenwich Peninsula submerged by water. The flood would have also stretched over Rotherhithe.
Do we need a new Thames Barrier?
That’s more often than in all previous years combined since it began its job of protecting London from flooding in 1982. The Environment Agency have said there are no plans to update the barrier until at least 2070.
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.
Would London flood without Thames barrier?
Without the barrier London landmarks such as the Houses of Parliament, the O2 arena and Tower Bridge would be submerged by flood water.
Does London sewage go into the Thames?
London relies on a 150-year-old sewer system built for a population less than half its current size. As a result, millions of tonnes of raw sewage spills, untreated, into the River Thames each year.
Why is London sinking slowly?
A warming of the ocean and increased melting of land-based ice, such as glaciers and ice sheets, is behind rising sea levels, which then have a knock on effect on our rivers, such as the Thames which runs through the capital.
How many bombs are in the Thames?
As historian Peter Ackroyd writes in Thames: The Biography, “It was estimated, at the end of , that approximately 15,000 high-explosive bombs, 350 parachute mines, 550 flying bombs and 240 rockets had fallen upon the Thames and dockland in the course of 1,400 raids.
Why can you not swim in the Thames?
The tidal Thames is a fast-flowing waterway and the busiest inland waterway in the UK accommodating over 20,000 ship movements and hosting over 400 events each year. It is for these reasons the PLA restricts swimming throughout the majority of its jurisdiction for the safety of swimmers and river users.
Can the Thames Barrier fail?
“A failure of the Thames Barrier is inevitable and, on current projections, will happen soon,” says Din. In the 1940s, a tidal surge of 3.66 metres was recorded in the Thames but hit at low tide, leaving the city unscathed.
What would happen if London flooded?
In the event of a mega-flood, the curvy nature of the Thames would disappear and almost all the land to the coast would be swamped. It would crawl out over the city. Absolutely, and it would be about a metre deep. Low-lying areas would be a problem, like Woolwich.
Why is the Thames Barrier effective?
With no barrier, at high tide, the sea would normally flow up the estuary and into London, pushing the river water back. With all the extra rainfall, this could worsen the flooding. The barrier prevents this from happening. The gates are left shut and the river water is held until the tide turns.
Can the Thames freeze over?
The Thames freezes over more often upstream, beyond the reach of the tide, especially above the weirs, of which Teddington Lock is the lowest. The last great freeze of the higher Thames was in 1962–63. Frost fairs were a rare event even in the coldest parts of the Little Ice Age.
Can Thames dry up?
The source of the river Thames has dried up due to extremely hot weather and drought. During the past six months, the start of the world famous river has become no more than a dirt track.
Can you walk under the Thames Barrier?
The Thames path goes right through the middle of it all, with fences either side offering protection, but it’s unusual to be able to walk through industry like this. After passing through this area you join a road ahead.
Does the London Underground go under water?
The District, Victoria, Northern, Bakerloo, and East London lines all run under the Thames, and the Underground sees approximately 4.8 million passenger journeys a day.

What is the future of the Thames Barrier?
While we expect the Thames Barrier to continue to protect London until 2070, we need to plan ahead now to keep London protected from storm surges. By 2040 we will make a decision on the preferred option for 2070 and beyond.
Where does poo go in London?
Taking the wastewater away
Whenever you flush the toilet or empty the sink, the wastewater goes down the drain and into a pipe, which takes it to a larger sewer pipe under the road. The sewer then joins our network of other sewers and takes the wastewater to a sewage treatment works.
