Tidal activity

I edited the paragraph about sea level rise to explain that most of the increase in sea levels is due to climate change and only a small part is due to the South of England sinking. I included a reference to a NASA web page that shows sea levels in Dove (on the South of England) rose by an average of 1.87mm a year between 1993 and 2019. Of this, NASA believes that only 0.42mm is due to the land sinking, the rest is due to thermal expansion of the oceans and ice melt from melting glaciers, both due to climate change. — Preceding unsigned comment added by Andrew 321321 (talk • contribs) 14:11, 7 June 2025 (UTC)

Environment

I think a citation is needed for the claim that sewage outflows into the river happen 'several times a year' - I only recall one in recent memory (maybe the last 5 years?), during a flood period. Mildlydiverting (talk) 10:03, 3 December 2009 (UTC)

Ooh, talking to myself - I've found some (not very well organised) data on the DEFRA / Environment agency sites that confirms the volume of sewage outflow issues. Will see if can add in a sensible way to the article. Mildlydiverting (talk) 10:48, 3 December 2009 (UTC)

Tidal Reaches

Please could the article include something about the tidal reaches of the Thames. How are they defined and what are the names (eg. Blackwall Reach, Erith Reach ...)? --Rob Kam (talk) 10:35, 3 February 2011 (UTC)

Now included, copied from Watermen#See_also --Rob Kam (talk) 20:47, 2 September 2013 (UTC)

I have added the two lower reaches, the Lower Hope and Sea Reach. Pterre (talk) 16:46, 3 September 2013 (UTC)

History

Needed. Some sources give Londinium as the tidal limit of the Thames at the time of its founding, while Staines-upon-Thames claims it was the tidal limit until the 14th century. — LlywelynII 17:33, 22 February 2015 (UTC)

Tidal activity

Someone requested clarification/citation for "Because the tide goes against the outflow of fresh water from the Thames Basin, it takes longer to subside (6–9 hours) than it does to flow in (4–5 hours)."

I don't have a citation but I think I can clarify. Whereas a bay without a river flowing into it would only have water flowing in from the ocean during a rising tide, the river has has water flowing both downstream and in from the ocean causing it to rise faster. Conversely when the tide turns the river continues to flow downstream, like trying to drain a tub with the faucet still running. 216.154.2.233 (talk) 06:40, 25 November 2024 (UTC)
