According to Merriam-Webster, a ravine is "a small, narrow, steep-sided valley that is larger than a gully and smaller than a canyon and that is usually worn by running water". [1] Some societies and languages do not differentiate between a gully and ravine; in others, there is a distinction, particularly when concerning environmental ...
Ravine – Small valley, often due to stream erosion; Ria – Coastal inlet formed by the partial submergence of an unglaciated river valley; Ridge – Long, narrow, elevated landform; Riffle – Shallow landform in a flowing channel; Rift valley – Linear lowland created by a tectonic rift or fault; River – Natural flowing freshwater stream
In southern Louisiana the word coulée (also spelled coolie) originally meant a gully or ravine usually dry or intermittent but becoming sizable during rainy weather. As stream channels were dredged or canalized, the term was increasingly applied to perennial streams, generally smaller than bayous. The term is also used for small ditches or ...

A deep crack, fissure, or chasm in the ice of a glacier or ice sheet, or more generally in any ground surface. 2. A break in the natural levee or bank of a river. [4] crust
Example on a topographical map, and how it would look in the real world. Typical draw, Little Carpathians A draw, sometimes known as a re-entrant in orienteering, is a terrain feature formed by two parallel ridges or spurs with low ground in between them.
Australian creek, low in the dry season, carrying little water. The energetic flow of the stream had, in flood, moved finer sediment further downstream. There is a pool to lower right and a riffle to upper left of the photograph.
Grand Canyon, Arizona, at the confluence of the Colorado River and Little Colorado River.. A canyon (from Spanish: cañón; archaic British English spelling: cañon), [1] gorge or chasm, is a deep cleft between escarpments or cliffs resulting from weathering and the erosive activity of a river over geologic time scales.

The creek that may have run along the bottom of the gulch in the past has been diverted to a parallel aryk. A gulch is a deep V-shaped valley formed by erosion. It may contain a small stream or dry creek bed and is usually larger in size than a gully. [1] Sudden intense rainfall upstream may produce flash floods in the bed of the gulch.
