UK: Flood project restores London's lost river

One of London's historic watercourses was brought back to life as part of an award-winning flood defence project. The river Quaggy in Lewisham, South East London, was forced underground when the area urbanised, with most of the river's 17 kilometre course now artificially channelled underground. But the Environment Agency has now brought a section of the river back to the surface as part of a local flood alleviation scheme, using historical data to cut its channel through Sutcliffe Park in Greenwich.
