The Thames Estuary is the estuary in which the River Thames meets the waters of the North Sea.
It is not easy to define the limits of the estuary, although physically the head of Sea Reach, near Canvey Island on the Essex shore is probably the western boundary. The eastern boundary, as suggested in a Hydrological Survey of 1882-9, is a line drawn from North Foreland in Kent via the Kentish Knock lighthouse to Harwich in Essex. It is to here that the typical estuarine sandbanks extend. The estuary has a tidal movement of 4 metres, moving at a speed of 8 miles per hour.
The estuary is one of the largest of 170 such inlets on the coast of Great Britain. It constitutes a major shipping route, with thousands of movements each year including large oil tankers, container ships, bulk carriers and roll-on/roll-off (ro-ro) ferries entering the estuary for the Port of London and the Medway Ports of Sheerness, Chatham and Thamesport.
The Thames sailing barge worked in this area, designed to be suitable for the shallow waters in the smaller ports. One of the largest wind farms in the UK has been developed in the estuary, located 8.5 km north of Herne Bay. The farm contains 30 wind turbines generating a total of 82.4MW of electricity. The much larger London Array of up to 1GW capacity is also planned.
This area has had several proposed sites for the building of a new airport to supplement, or even to replace Heathrow. In the 1960s Maplin Sands was a contender; in 2002 it was to be at Cliffe, Kent. The new airport would be built on a man-made island in the estuary north of Minster-in-Sheppey There is also some discussion about the need for a Lower Thames Crossing in order to alleviate traffic congestion at Dartford.
The Thames Estuary is part of Thames Gateway, designated as one of the principal development areas in Southern England.

Famous quotes containing the words thames and/or estuary:
“Home! Yes! she would see Trafalgar Square, again; and Nelson on his plinth; and Chelsea Bridge as it dissolved into the Thames at twilight ... and St. Paul’s, the single Amazon breast of her beloved native city.”
—Angela Carter (1940–1992)
“There is regret. Always, there is regret.
But it is better that our lives unloose,
As two tall ships, wind-mastered, wet with light,
Break from an estuary with their courses set,
And waving part, and waving drop from sight.”
—Philip Larkin (1922–1986)
