(Translate & Speak Website: http://imtranslator.net/translate-and...) A pictorial demonstration of Chapter 18 (Design & Construction of a Farm Dam). http://www.soilandhealth.org/01aglibrary/010126yeomansii/010126ch18.html from the book: Yeomans, P.A. (1958). The Challenge of Landscape. Sydney, NSW: Keyline Publishing Pty Ltd. http://www.soilandhealth.org/01aglibrary/010126yeomansii/010126toc.html This first time digitized film opens with sweeping views of Yobarnie and Nevallan, North Richmond NSW. Keyline and other dams are shown along with water release irrigation. Grazing cattle are also seen. The film then shifts to a yet to be confirmed property where the complete pictorial demonstration of the building of a Keyline (Saddle) Dam takes place. Notes: 1. The saddle itself is the Keypoint and is the exit point for a natural gently falling dam spillway into the equivalent Primary Valley on the other side of the Main Ridge. See Fig. 7 in Chapter 6 (Land Shape) of the above book: http://www.soilandhealth.org/01aglibrary/010126yeomansii/010126ch6.html 2. For the final smoothing of the reintroduced top soil over the dam wall itself, the use of a dragged chain between two bulldozers travelling in parallel along the wall crest and the toes of the wall is shown.
