Talk:River Tweed

Length of river

I have provided a reference for the length of the Tweed (156km / 97 miles) whereas no reference had previously been provided. I am concerned however that is possible that the author of the book from which it comes may have taken that figure from Wikipedia in the first instance as it was certainly in the article prior to the publication of the book. I simply don't know. For the record, I have, as with some other watercourses where dubious lengths have been asserted, painstakingly measured its length myself on online 1:25,000 scale OS mapping using a digital tool and determined it at 163.6km / 101.7 miles - I'd be confident of the accuracy of the figure to within about 0.5%. This latter figure is of course original research on my part so cannot be included in the article but it does at least give an idea of what a true figure should look like if and when an editor finds a suitable reference out there! cheers Geopersona (talk) 19:04, 11 August 2022 (UTC)

Original research is forbidden, as it cannot be recorded sufficiently. This is important on physical measurements, on chemical experiments, on observations of changing scenes (If you do a traffic count, even a movie is no suffizient documentation, as you can cut it). Suggestion: Draw a GPS-track of the course and link it here. This way, many other users can control, wether you followed the course of water sufficiently exactly.--Ulamm (talk) 11:24, 5 January 2026 (UTC)

River names Tweed and Teviot

Both names, Tweed and Teviot, look like derivates of one singe etymologic origin.

Other such cases are found with headwaters, but also tributaries could have the same name as their target river, see all those Gardon tributaries of river Gard in France.

I tried to follow the Welsh Language link of this article and another link for Welsh language, but I was not successful.--Ulamm (talk) 11:08, 5 January 2026 (UTC)
