London - Thames Flood Barrier

The Thames Barrier, which crosses the river near Woolwich 13km/8mi east of the City of London, was inaugurated on May 8, 1984. This technical masterpiece, 520m/569yd wide, is the largest movable flood barrier in the world. Nine piers were sunk in the river bed and between them are 10 steel gates. The powerful hydraulic lifting rams take 30 minutes to move the gates into position.

Downstream eight smaller barriers were constructed, which can block off some of the tributaries of the river. By this means a guarantee against flooding of large areas of Kent and Essex in a catastrophe can be assured. The Thames Barrier was necessary because the risk of flooding has been intensified by the gradual sinking of eastern England and an increase in the storms in the North Sea and the English Channel. British experts are of the opinion that in a few decades even larger flood barriers must be built.

Visits to the actual barrier are not permitted but there are good views from a riverside walk. In the visitors' center there is a most interesting audio-video show concerning the construction and functioning of the Thames Barrier.
