Sea level

Sediment cores up to 10 m deep collected by the British Geological Survey from the banks of the tidal River Thames contain geochemical information and fossils which provide a 10,000-year record of sea-level change. Combined, this and other studies suggest that the Thames sea-level has risen more than 30 m during the Holocene at a rate of around 5–6 mm per year from 10,000 to 6,000 years ago. The rise of sea level dramatically reduced when the ice melt nearly concluded over the past 4,000 years. Since the beginning of the 20th century, rates of sea level rise range from 1.22 mm per year to 2.14 mm per year.


Catchment area and discharge

The Thames River Basin District, including the Medway catchment, covers an area of . The river basin is a mixture of urban through to rural in the east and northern parts while the western parts of the catchment are predominantly rural with many towns to a suburban layout such as, archetypically Swindon. The area is among the driest in the United Kingdom. Water resources consist of

from aquifers and water taken from the Thames and its tributaries, much of it stored in large bank-side reservoirs. The Thames itself provides two-thirds of London's drinking water while groundwater supplies about 40 percent of public water supplies in the total catchment area. Groundwater is an important water source, especially in the drier months, so maintaining its quality and quantity is extremely important. Groundwater is vulnerable to surface pollution, especially in highly urbanised areas.

). All the erosion down from this higher land surface, and the sorting action by these changes of water flow and direction, formed what is known as the Thames River Gravel Terraces. Since Roman times and perhaps earlier, the isostatic rebound from the weight of previous ice sheets, and its interplay with the eustatic change in sea level, have resulted in the old valley of the River Brent, together with that of the Thames, silting up again. Thus, along much of the Brent's present-day course, one can make out the water-meadows of rich alluvium, which is augmented by frequent floods.

. As early as the 1300s, the Thames was used to dispose of waste matter produced in the city of London, thus turning the river into an open sewer. In 1357, Edward III described the state of the river in a proclamation: "... dung and other filth had accumulated in divers places upon the banks of the river with ... fumes and other abominable stenches arising therefrom."Peter Ackroyd, Thames: The Biography, New York: Doubleday, 2007. "Filthy River" The growth of the population of London greatly increased the amount of waste that entered the river, including human excrement, animal waste from slaughter houses, and waste from manufacturing processes. According to historian Peter Ackroyd, "a public lavatory on London Bridge showered its contents directly onto the river below, and latrines were built over all the tributaries that issued into the Thames."

The Thames provided the major route between the City of London and Westminster in the 16th and 17th centuries; the clannish guild of watermen ferried Londoners from landing to landing and tolerated no outside interference. In 1715, Thomas Doggett was so grateful to a local waterman for his efforts in ferrying him home, pulling against the tide, that he set up a rowing race for professional watermen known as " Doggett's Coat and Badge". By the 18th century, the Thames was one of the world's busiest waterways, as London became the centre of the vast, mercantile

and beyond. Efforts were made to resolve the navigation conflicts upstream by building locks along the Thames. After temperatures began to rise again, starting in 1814, the river stopped freezing over. The building of a new London Bridge in 1825, with fewer piers (pillars) than the old, allowed the river to flow more freely and prevented it from freezing over in cold winters. Throughout early modern history the population of London and its industries discarded their rubbish in the river. This included the waste from slaughterhouses, fish markets, and tanneries. The buildup in household cesspools could sometimes overflow, especially when it rained, and was washed into London's streets and sewers which eventually led to the Thames.

In many river sports and traditions – for example in rowing – the banks are referred to by their traditional county names.

from all the towns and villages in the Thames catchment flow into the Thames via sewage treatment plants. This includes all that from Swindon, Oxford, Berkshire and almost all of Surrey. However, untreated sewage still often enters the Thames during wet weather. When London's sewerage system was built, sewers were designed to overflow through discharge points along the river during heavy storms. Originally, this would happen once or twice a year, however overflows now happen once a week on average. In 2013, over 55 tonnes of dilute raw sewage overflowed into the tidal Thames. These discharge events kill fish, leave raw sewage on the riverbanks, and decrease the water quality of the river. To reduce the release of this into the river, the

, have been analysed for total Hg. The sediment records show a clear rise and fall of Hg pollution through history. Mercury concentrations in the River Thames decrease downstream from London to the outer Estuary, with the total Hg levels ranging from 0.01 to 12.07 mg/kg, giving a mean of 2.10 mg/kg which is higher than many other UK and European river estuaries. The most sedimentary-hosted Hg pollution in the Thames estuary occurs in the central London area between Vauxhall Bridge and Woolwich. The majority of sediment cores show a clear decrease in Hg concentrations close to the surface, which is attributed to an overall reduction in polluting activities as well as improved effectiveness of recent environmental legalisation and river management (e.g. Oslo-Paris convention).

. The book was intended initially to be a serious travel guide, with accounts of local history of places along the route, but the humorous elements eventually took over. The landscape and features of the Thames as described by Jerome are virtually unchanged, and the book's enduring popularity has meant that it has never been out of print since it was first published.

' '' Our Mutual Friend'' (written in the years 1864–65) describes the river in a grimmer light. It begins with a scavenger and his daughter pulling a dead man from the river near London Bridge, to salvage what the body might have in its pockets, and leads to its conclusion with the deaths of the villains drowned in Plashwater Lock upstream. The workings of the river and the influence of the tides are described with great accuracy. Dickens opens the novel with this sketch of the river, and the people who work on it:
''In these times of ours, though concerning the exact year there is no need to be precise, a boat of dirty and disreputable appearance, with two figures in it, floated on the Thames, between
