A terrace consists of a flat or gently sloping geomorphic surface, called a tread, that is typically bounded on one side by a steeper ascending slope, which is called a “riser” or “scarp”. The tread and the steeper descending slope (riser or scarp) together constitute the terrace. … Terraces are formed in various ways.
Why are slopes terraced?
Terraces divide slopes so that surface runoff is intercepted and carried to a protective outlet. Terraces decrease erosion by shortening slope length, slowing runoff velocity, and trapping sediments. Runoff water concentrates in waterways that when bare or unstable are extremely erodible.
How do you make terraces on a slope?
To do this, dig an 8–10-inch deep trench, pour 4 inches of gravel in the trench, and lay your first course of stone. Build your wall to the desired height, backfill it with gravel and dirt, and level the terraced area. Once complete, you can move on up the slope and build additional terrace walls.
