Anybody know what a swale and a keyline system is??
I'm not up on my irrigation terms.
Neither of these are irrigation sytems.
Both of these are techniques to hold water (from rain) and soil on a slope.
There is a whole book on keyline stuff, but one of the most popular techniques is to use a keyline plow (not a regular plow) which sorts digs a tiny channel about 18 inches underground
. And you want this channel to run slightly downhill AWAY from ravines.
A swale is like a ditch that is perfectly level. So rain water builds up in it and passes through it. The swale holds soil and concentrates moisture.
