Use diversions 21 Use diversions Detailed image. . . A diversion is a graded channel, constructed across the slope with a ridge running along its lower side. It conveys water away from its present source to another location.
Diversions often function like terraces.
But whereas a terrace is part of a larger system, a diversion often stands alone, serving one specific purpose. Also, a diversion typically handles a greater flow of water coming from a larger area than an individual terrace does. Do not use diversions as a substitute for terraces.
