Gully erosion occurs as water flows down narrow channels after rainstorms and melting snow. Unlike rill beds, gullies typically remain intact, despite the surrounding tillage operations. A gully ranges in varying depths, usually ranging around one or two feet up to as much as one hundred feet.

Through erosion, a river creates valleys, waterfalls, flood plains, meanders and oxbow lakes. Sediment deposited where a river flows into an ocean or lake builds up a land form called a delta. Corrosion or erosion of the surfaces of metals under water is in many cases found to be actively promoted by their motion through the water, or by the motion of the water over them. In such cases the relative parts played in the action by corrosion and erosion respectively are not readily distinguished. A recent JRC study finds that soil erosion by water costs the world economy about US$8,000,000,000 (eight billion US dollars) a year..
