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. Witches Gulch found in the Dells of the Wisconsin River. In eastern Canada, gulch refers to: [2]
Klingen are small, narrow, steep V-shaped valleys formed by the erosive forces of water and suspended abrasive particles, gravel and pebbles.They are usually side valleys without a discernible valley floor that lead into a main valley.
Coulee – Type of valley or drainage zone; Couloir – Steep, narrow mountain gully – a narrow gully with a steep gradient in a mountainous terrain; Dale (landform) – Open valley; Draw (terrain) – Terrain feature formed by two parallel ridges or spurs with low ground in between; Gulch – Deep V-shaped valley formed by erosion

In polar areas and at high altitudes, valleys may be eroded by glaciers; these typically have a U-shaped profile in cross-section, in contrast to river valleys, which tend to have a V-shaped profile. Other valleys may arise principally through tectonic processes such as rifting. All three processes can contribute to the development of a valley ...
The customary view is that valleys are carved by running water eroding path through land (in the case of V-shaped valleys), or by glaciers scouring across slopes (in the case of U-shaped valleys); however, there is evidence that rivers and ice follow pre-existing tectonic structures, meaning that valleys are created by both flows and tectonic ...
Devil's Dyke is a 100 metre (300') deep V-shaped dry valley on the South Downs in Sussex in southern England, 5 miles (8.0 km) north-west of Brighton.It is managed by the National Trust, and is also part of the Beeding Hill to Newtimber Hill Site of Special Scientific Interest. [1]
Dendritic drainage: the Yarlung Tsangpo River, Tibet, seen from space: snow cover has melted in the valley system. In geomorphology, drainage systems, also known as river systems, are the patterns formed by the streams, rivers, and lakes in a particular drainage basin. They are governed by the topography of land, whether a particular region is ...
