Where Does the River Thames Flow?

The Thames Empties into the North Sea

The River Thames does not flow directly into an ocean. It flows eastward across southern England and discharges into the North Sea via the Thames Estuary.

Details

• Source: Thames Head, Gloucestershire (Cotswolds).
• Length: 346 km (215 mi) — longest river entirely in England.
• Tidal limit: Teddington Lock (London); below this, the river is tidal (the Tideway).
• Estuary: Broadens from Gravesend to the Nore sandbank, where it meets the North Sea.

North Sea Context

The North Sea is a marginal sea of the Atlantic Ocean, bounded by Great Britain, Scandinavia, Germany, Netherlands, Belgium, and France. It connects to the Atlantic via the English Channel (south) and Norwegian Sea (north).

Significance

• London's historic port developed on the tidal Thames.
• Thames Barrier (1982) protects London from storm surges.
• Major shipping channel; ecology recovering from past pollution.

So: Thames → Thames Estuary → North Sea → Atlantic Ocean.
