In 1966, Sir Hermann Bondi was asked to take an independent view of the situation. By 1965, when the Greater London Council (GLC) took over responsibility, two major schemes were under consideration, costed at £24 million and £41 million respectively (£500 million and £800 million at 2020 prices). A number of designs were put forward, from a huge road viaduct with two 500 foot (150 m) sluice gates crossing the Thames at Crayfordness to flap gates lying on the river bed and floated up by compressed air. In 1954, the Waverley Committee, established to investigate the serious North Sea flood of 1953 which affected parts of the Thames Estuary and parts of London, recommended that "as an alternative to raising the banks, the possibility and cost of erecting a structure across the Thames which could be closed in a surge should be urgently investigated". Built about 2 miles (3.2 kilometres) east of the Isle of Dogs, its northern bank is in Silvertown in the London Borough of Newham and its southern bank is in the New Charlton area of the Royal Borough of Greenwich.įlooding in London has been a problem since Roman times. When needed, it is closed (raised) during high tide at low tide, it can be opened to restore the river's flow towards the sea. The Thames Barrier is a retractable barrier system built to protect the floodplain of most of Greater London from exceptionally high tides and storm surges moving up from the North Sea.

The province is also continuing to search for a suitable site to build a similar dam along the Bow River, upstream from Calgary, said McIver.
