These valleys tend to have high, steep walls. "Hollow" is used as a synonym, often for the smallest of such valleys. The term is also applied to the greater La Crosse, Wisconsin metropolitan area (i.e. the "Coulee Region"). [4] The Gassman Coulee in North Dakota may have been a contributing factor to the flooding of the Souris River in June 2011.
The topography of the San Luis Rey valley which effects the area's climate. The petition provided climate data, specifically the average annual mean temperature, average annual maximum temperature, average peak ripening and harvest season maximum temperature, and growing degree day (GDD) accumulations for the AVA and surrounding regions.

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]
Lightband Gully, sometimes also Lightbands or Lightband's Gully, is a valley in the hills behind the Golden Bay / Mohua township of Parapara in New Zealand. The valley is notable as the site of the first payable gold discovery—in October 1856—in the South Island, and this started the Golden Bay gold rush.
Gully erosion may also advance laterally through similar methods, including mass movement, acting on the gully walls (banks), and the development of 'branches' (a type of tributary). Gullies reduce the productivity of farmlands where they incise into the land and produce sediment that may choke downstream waterbodies and reduce water quality ...
Badlands are characterized by a distinctive badlands topography. [3] [4] This is terrain in which water erosion has cut a very large number of deep drainage channels, separated by short, steep ridges (interfluves). [5] Such a drainage system is said to have a very fine drainage texture, [6] as measured by its drainage density. Drainage density ...
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.
Gully erosions occur due to sandy soil being unable to withstand the runoff and eventually eroding away, leaving gaping gullies that swallow homes and other infrastructure. Gullies and areas exposed to erosion in South Eastern Nigeria tripled from about 1.33% (1,021 km 2 ) in 1976 to about 3.7% (2,820 km 2 ) in 2006, making the region the most ...
