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. Sudden intense rainfall upstream may produce flash floods in the bed of the gulch.
In eastern Canada, gulch refers to:
- a narrow deep cove (Newfoundland)
- a narrow saltwater channel (Nova Scotia)
