Physical features The Thames is some 205 miles (330 km) long, running 140 miles (226 km) from the source to the tidal waters limit—i.e., from Thames Head to Teddington Lock—and, as an estuary, a further 65 miles (104 km) from there to The Nore sandbank, which marks the transition from estuary to open sea.

About River Thames
The Thames is one of the World’s most fascinating and beautiful rivers. From source to sea, its 215 miles flow from springs in Gloucestershire through rural and developed areas to London and on to the imposing tidal estuary into the North Sea.
What are the different features of the River Thames drainage basin?
Approximately two-thirds of the basin is permeable (allows water to soak through), consisting of chalk, middle Jurassic limestones, and river gravels. The remaining third of the basin consists mainly of low permeability strata, such as clay; here, surface water runs off directly into watercourses (streams and rivers).

Is the Thames salty?
Between Teddington and Chelsea the tidal Thames is freshwater, from Chelsea downstream it becomes more mixed (“brackish”) until it becomes a marine environment below Greenwich. This change in salt levels impacts the types of fish and wildlife you find in different stretches of the river.
Why is the River Thames so clean?
Thames Water, a private utility company in charge of London’s water supply and waste water, says it removes more than 25,000 tonnes of debris from their sewage system every year.
Why is the Thames water salty?
As observed on Floating Down the River, while the river does start turning saline after Teddington, because of its irregular, serpentine nature — which mixes together fresh and salty water — the Thames remains more or less freshwater all the way to Battersea. Even then, the water’s only brackish, not saline, per se.
What are the major features of a river system?
Features in the upper course: V-shaped valleys – The river erodes as it travels and it carves the valley floor. Waterfalls – The river can erode the softer rock layers, which leaves behind an over-hang of harder rock. Tributaries – These are small rivers and/or streams that join together into the river.
What are the different types of river features?
The formation of valleys, interlocking spurs, waterfalls, meanders, oxbow lakes, flood plains and levees.

Why is the water in the Thames so dirty?
“Because London’s sewage system was largely built in the 1800s when London’s population was less than a quarter of what it is today, storm events cause excess sewage to overflow into the Tidal Thames, posing a major threat to water quality,” the report says.
Why is the Thames river in London so dirty?
Much of London’s drinking water comes from the river. Among modern cities, the Thames hasn’t always been a model for successful environmental protection. It became heavily polluted during the Industrial Revolution as toxic runoffs from tanneries and human waste found their way to the river.
Why does the Thames no longer freeze?
Sadly, the Thames will never see another Frost Fair: due to climate change, the construction of the new London Bridge in 1831, and because the river was dredged and embanked during the Victorian era, making it too deep and swift-flowing to freeze as it once did.
How old is Thames?
The story of the River Thames goes back to over 30 million years ago when the river was once a tributary of the River Rhine because Britain was not an island. During the Great Ice Age 10,000 years ago the Thames changed its course and pushed through the Chiltern Hills at a place we now call The Goring Gap.
Did the Thames ever ice over?
Between 1600 and 1814, it was not uncommon for the River Thames to freeze over for up to two months at time. There were two main reasons for this; the first was that Britain (and the entire of the Northern Hemisphere) was locked in what is now known as the ‘Little Ice Age’.
