A gully is a small, narrow channel or ravine formed by the erosion of soil and rock, typically caused by water runoff. It often appears in landscapes where heavy rainfall or melting snow leads to concentrated water flow, which carves out the ground over time. Gullies can vary in size and depth, and they are commonly found in hilly or mountainous areas. Gullies play an important role in the ecosystem by directing water flow and influencing local vegetation. They can also contribute to soil erosion, which may affect agricultural land and water quality in nearby rivers and streams. Proper management is essential to prevent excessive erosion and maintain healthy landscapes.
