Ravines and gullies are erosional features that exist on a continuum of scales. A ravine is defined as a small, narrow, and deep depression, smaller than a valley, and larger than a gully (Bates and Jackson, 1984). Both grow by head cutting. Ravines are usually longer and deeper than gullies. Gullies may be small enough to plow, these are ephemeral gullies.
