~ Terraces

A Terrace is an earth embankment or a combination ridge and channel constructed across the field slope that intercepts, detains, and safely conveys runoff to an outlet. Terraces are used to reduce sheet-and-rill erosion and prevent gully development. Terracing reduces sediment pollution to lakes and streams, and traps phosphorus attached to sediment particles. Terraces may also retain runoff for moisture conservation.
