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. It has 10 steel gates that can be raised into position across the River Thames. When raised, the main gates stand as high as a 5-storey building and as wide as the opening of Tower Bridge. Each main gate weighs 3,300 tonnes. The barrier is closed under storm surge conditions to protect London from flooding from the sea. It may also be closed during periods of high flow over Teddington Weir to reduce the risk of river flooding in some areas of west London including Richmond and Twickenham. The Thames Barrier will then remain closed over high water until the water level downstream of the Thames Barrier has reduced to the same level as upstream. This is a managed process to provide for different circumstances, and takes about 5 hours. The Thames Barrier is then opened, allowing the water upstream to flow out to sea with the outward-bound tide.

Thames Barrier, London

Another shot from the Thames Barrier in Greenwich, with sunset rapidly approaching there was a good amount of golden soft light to play with, the lower light allowing a decent long exposure time, just showing of a lone section of the river defence, these to me are a very interesting and unusual architectural design, almost space age, and set against some recognisable shapes in the City make for some unusual images when coupled with a long exposure.

The classic view of the Thames Barrier from Woolwich on the south bank of the Thames, with a bit of LE thrown in.
