A gully is a small, narrow channel or ravine formed by the erosion of soil and rock, often caused by water runoff. It typically appears in landscapes where rainfall is heavy, leading to the concentration of water flow that carves out the ground over time. Gullies can vary in size and depth, and they are commonly found in hilly or mountainous regions. Gullies play a significant role in the ecosystem by directing water flow and influencing sediment transport. They can also impact agriculture and land use, as they may lead to soil loss and affect crop production. Proper management of gullies is essential to prevent further erosion and maintain land health.
