Satellite image of the Cayman Trough Bathymetric features of the Rockall Trough northwest of Scotland and Ireland. In geology, a trough is a linear structural depression that extends laterally over a distance. Although it is less steep than a trench, a trough can be a narrow basin or a geologic rift. These features often form at the rim of ...

The Trough, photographed on July 3, 2016. The Trough is a 6-mile long wooded gorge carved by the South Branch Potomac River (SBPR) and situated in the Allegheny Mountains of Hampshire and Hardy Counties, West Virginia, US.

An abreuvoir is a watering trough, fountain, or other installed basin: originally intended to provide humans and/or animals at a rural or urban watering place with fresh drinking water. They were often located at springs. In pre–automobile era cities, they were built as equestrian water troughs for horses providing transportation.
A view through a coulee in Alberta, with steep but lower sides, and water in the bottom. Coulee, or coulée (/ ˈ k uː l eɪ / or / ˈ k uː l iː /), [1] is any of various different landforms, all of which are kinds of valleys or drainage zones. The word coulee comes from the Canadian French coulée, from French couler 'to flow'.
In glacial valleys or trough valleys, it may be referred to as the trough head or trough end. [2] In mountains with predominantly crystalline rock the heads of the valleys are generally very wet, sometimes boggy and often support lush alpine meadows, whilst those made of limestone are usually dry and covered in talus or gravel.
