Dobbingstone Burn, Scotland, showing two different types of erosion affecting the same place. Valley Coastal erosion. Shoreline erosion, Moving water such as currents in oceans or rivers plays a significant role in erosion because they move materials from their primary source to a separate location. Erosion may discolor rivers as they snake through the valleys to oceans or seas. This is due to the huge amount of sediment deposited by the process of erosion. Geological landscapes may erode from one of five types of water erosion.

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.. This lost soil reduces global agri-food production by 33.7 million tonnes, leading to increases of up to 3.5% in world food prices, and widens the competitive gap on world agri-food markets. Water Erosion.

Internal erosion is the formation of voids within a soil caused by the removal of material by seepage. It is the second most common cause of failure in levees and one of the leading causes of failures in earth dams, responsible for about half of embankment dam failures.

Erosion is distinct from weathering which involves no movement. Water erosion occurs when rain, spring run-off, or floodwater carry soil particles away. This can occur through sheet erosion, where soil materials are removed relatively uniformly, or rill erosion where flowing water creates small channels in the soil, called rills, and larger channels, called gullies. 2019-01-31 · Running water: erosion, transportation, and deposition.
