The swale concept has also been popularized as a rainwater harvesting and soil conservation strategy by Bill Mollison, Geoff Lawton and other advocates of permaculture. In this context it usually refers to a water harvesting ditch on contour. Another term used is contour bund.
I'm curious, Peter, how you would explain the difference between a swale and a ditch if they can both direct water?
