Definition

An open conduit through which some fluid has moved (Sharp and Malin 1975). On Earth, a channel is defined as “the hollow bed where a natural body of surface water flows or may flow. The deepest or central part of the bed of a stream, containing the main current and occupied more or less continuously by water” (NSSH 2008).

Description and Terminology

Channel

On Earth, the term “channel” refers to the bed and bank of a stream, lying at the bottom of a gully, canyon, or valley (Sharp and Malin 1975), but it is also applied to lava channels and submarine channels.

On Mars, it has come to mean any elongate narrow depression of linear, curvilinear, sinuous, or irregular configuration, created by external processes, typically erosion (Sharp and Malin 1975). However, the application of the term “channel” to any linear negative landforms of Mars is inappropriate in terms of strict terminology (Sharp and Malin 1975...
