  "definition": "1. The removal of soil by concentrated water running through little streamlets, or headcuts. Detachment in a rill occurs if the sediment in the flow is below the amount the load can transport and if the flow exceeds the soil's resistance to detachment. As detachment continues or flow increases, rills will become wider and deeper.\n\n2. The movement of sediment through one of the first and smallest channels formed by water runoff. The size distinction is not formal but has generally been defined as narrower than 12 inches.\n\n3. An erosion process in which numerous small channels of only several centimeters in depth are formed; occurs mainly on recently cultivated soils.\n\n4. The removal of soil by the cutting of numerous small, but conspicuous, water channels or tiny rivulets by concentrated surface runoff. Rill erosion is intermediate between sheet erosion and gully erosion.",
