Wow, the best explanation of keyline I've come across. Cleared up a lot of puzzlements from reading Water for Every Farm. Many thanks for this gift, Darren, and for so clearly translating this important work!
Good morning Susannah, My favourite books of P.A. Yeomans are 'The Challenge of Landscape' (1958) and 'The City Forest' (1971). There were two editions of 'Water for Every Farm' - one in 1966 and then another in 1975, the latter had a brown cover and here is a review I provided (along with reviews of the other Keyline books that Yeomans' and J.McDonald Holmes wrote): "...This piece, which was reprinted in 1981 by Second Back Row Press, is ostensibly an amalgam of ‘The Australian Keyline Plan’ (1954) and ‘Water for Every Farm’ (1966). P.A. Yeomans’ son Ken B. Yeomans made mention of the deficiencies of this piece in his 1993 edition using the same main title (see below). It is a useful piece however the errors that Ken mentions and its reference to the ‘Common Keyline’ concept has, I believe, been one of the primary causes for much confusion around Keyline geography and geometry. Well-known authors such as the late Bill Mollison and more recently Mark Shepard have perpetuated this erroneous geometry... You can read all the reviews on a post titled 'Keyline Books' on the Regrarians website here: www.regrarians.org/keyline-books-a-quick-review/ Sláinte! Darren
@@RegrariansThank you, Darren, for your helpful reply! I'll look into those books you recommend. I appreciate your time and your fine work. Wlinanawalmezi, Susanne
Yeomans defined the key point as the first point in the valley where the contour bands go from narrower than the adjacent ridges to wider than the adjacent ridges. Remember he was doing this well before satellite imagery and GPS
Great stuff, I would love to get my hands on a physical copy of the Handbook, from looking at the website the handbook is till being put together, is that correct?
Thanks Rick, Yes the Handbook project is still going along - stifled a lot by the pandemic restrictions and the designer having a series of family deaths, elderly parents to care for and the 2019/20 wildfires. We persist nonetheless. Sláinte! Darren
finally! a comprehensive explanation and demonstration. thank you
Thanks @robbo0090, we appreciate you comment and hope you found this useful.
All the best, Darren

Explanations without consistency and coherence. Very hard to believe that the concept has any scientific basis !!
well it seems to be working and the scientific basis has yet to be developed, what are you trying to achieve with this comment?
