Meaning and Definition
A narrow, winding, and often sunken channel through sand, caused by the flow of water (chiefly in coastal contexts).
A physical feature in coastal geomorphology where water has carved a groove, channel, or small watercourse in sandy or sedimentary terrain. The term is also used in South African English, influenced by Afrikaans, where it has a broader meaning referring to a shallow, often dry watercourse or gully, especially in the Karoo region.
