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.
a deep, narrow ravine, esp. one marking the course of a stream or torrent. [1825â35; compare British dial. gulch, gulsh to run with a full stream, gush, (of land) to sink in, Middle English gulchen to spew forth, gush; expressive word akin to gulp, gush, etc.]
