located on the north side of the River
Thames, encompasses an area of 3,600 ha
bound on three sides by tidal watercourses:

the east and the River Thames to the south.

In the south of the borough, the Royal Docks,
collectively form the largest enclosed docks
in the world and a major feature of the
borough. The Thames Barrier protects
Newham from flooding by tidal surges on
both the Thames and the Lea. The Barking
