P A Yeomans-Keyline in New Caledonia (20 min)
http://youtu.be/gkrZVIeaYxk
*Published on Jun 9, 2013 *
This is one of the first films depicting a Keyline Flood Flow system
consultancy by P A Yeomans, on near flat land adjacent to a swampy river
valley.
River water flows into a gently falling diversion channel all the way into
a shallow creek valley.
So that this water can irrigate the greatest area of land, a flat channel
takes the shortest path (making the water available higher in the
landscape) across the shallow creek valley on a viaduct wall, creating a
lake behind it.
River water is diverted into the lake or across the wall to a falling
irrigation channel.
In lieu of an overflow channel from the lake, flooded water-gates at the
end of the long arm of the storage (parallel to & uphill from the
irrigation channel) release water back down the plain into the now lower
irrigation channel.
For additional Keyline Flood Flow irrigation higher in the landscape,
Yeomans installs a low lift/high capacity pump along the same long arm of
the lake.
To maximise this higher irrigation area, the pumped water is sent into an
upper contour irrigation channel.
