  "definition": "1. They are formed when channel development has progressed to the point where the gully is too wide and too deep to be tilled across. These channels carry large amounts of water after rains and deposit eroded material at the foot of the gully. They disfigure landscape and make land unfit for growing crops.\n\n2. The erosion process whereby water accumulates in narrow channels and, over short periods, removes the soil form this narrow area to considerable depths, ranging from 1-2 feet to as much as 75-100 feet.\n\n3. Severe erosion in which trenches are cut to a depth greater than 30 centimeters (a foot). Generally, ditches deep enough to cross with farm equipment are considered gullies.\n\n4. The removal of soil by the formation of relatively large channels or gullies cut into the soil by concentrated surface runoff. In contrast to rills, gullies are too deep to be obliterated by ordinary tillage practices. (US. Soil Conserv. Serv. 1951)\n\n5. Severe erosion in which trenches are cut to a depth greater than 30 centimeters (one foot). Generally, ditches deep enough to cross with farm equipment are considered gullies.",
