Gulch

For other uses, see Gulch (disambiguation).

A dry gulch in the desert near Tamchy, Kyrgyzstan. The creek that may have run along the bottom of the gulch in the past has been diverted to a parallel aryk.

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.
