Enlarged Gully is a term used to describe a RAVINE that has been widened and deepened by erosion. It is usually caused by water running down the sides of a hill or mountain, which erodes the soil and rocks, creating a larger and deeper RAVINE than what was originally there. Enlarged gullies can be found in many different types of terrain, from deserts to mountains. They are often used as a source of water for irrigation and other purposes.
