Landforms related to rivers and other watercourses include: Channel (geography) – Narrow body of water; Confluence – Meeting of two or more bodies of flowing water; Cut bank – Outside bank of a water channel, which is continually undergoing erosion; Crevasse splay – Sediment deposited on a floodplain by a stream which breaks its levees
Gully – Landform created by running water and/or mass movement eroding sharply into soil; Guyot – Isolated, flat-topped underwater volcano mountain; Hanging valley – A tributary valley that meets the main valley above the valley floor; Headland – Landform extending into a body of water, often with significant height and drop
A gully in Kharkiv oblast, Ukraine. Gullied landscape in Somalia.. A gully is a landform created by running water, mass movement, or commonly a combination of both eroding sharply into soil or other relatively erodible material, typically on a hillside or in river floodplains or terraces.

The lower part of the piedmont is a bajada, with the distinction being that the upper pediment surface is cut into bedrock (with possibly a thin veneer of alluvium) and is thus a result of erosion, while the lower bajada is aggradational (formed by accumulation of fresh sediments). Above the pediment, the slope abruptly increases, with an angle ...
The model in its original form is intended to explain relief development in temperate landscapes in which erosion by running water is assumed to be of prime importance. [5] [7] Nevertheless, the cycle of erosion has been extended, with modifications, into arid, semi-arid, savanah, selva, glacial, coastal, karst and periglacial areas.
A ravine is a landform that is narrower than a canyon and is often the product of streambank erosion. Ravines are typically classified as larger in scale than gullies, although smaller than valleys. [1] Ravines may also be called a cleuch, dell, ghout , gill or ghyll, glen, gorge, kloof (South Africa), and chine (Isle of Wight)
The Doña Ana County Flood Commission in the U.S. state of New Mexico defines an arroyo as "a watercourse that conducts an intermittent or ephemeral flow, providing primary drainage for an area of land of 40 acres (160,000 m 2) or larger; or a watercourse which would be expected to flow in excess of one hundred cubic feet per second as the result of a 100 year storm event."
