soil erosion definition, meaning, English dictionary, synonym, see also 'soil',soil',acid soil',alkali soil', Reverso dictionary, English definition, English vocabulary More compacted soils will have a larger amount of surface runoff than less compacted soils. [30], Surface creep is the slow movement of soil and rock debris by gravity which is usually not perceptible except through extended observation. [105] Windbreaks (also called shelterbelts) are rows of trees and shrubs that are planted along the edges of agricultural fields, to shield the fields against winds. It also reduces their food supply, and causes major respiratory issues for them as sediment enters their gills. The term is often used in agriculture to refer to topsoil that is moved by natural forces or through agricultural activities such as tillage. The most direct is the change in the erosive power of rainfall. As soil erodes, it loses nutrients, clogs rivers with dirt, and eventually turns the area into a desert. Soil erosion is a natural or artificial process where the top layers of soil are blown or washed away from wind or water. Soil Erosion is the process that erodes, breaks or gradually diminishes things down. [57], The warmer atmospheric temperatures observed over the past decades are expected to lead to a more vigorous hydrological cycle, including more extreme rainfall events. Loss of total phosphorus, for instance, in the finer eroded fraction is greater relative to the whole soil. Flow depths in rills are typically of the order of a few centimeters (about an inch) or less and along-channel slopes may be quite steep. The upper layer of soil on farms typically contain the most nutrients and is best suited for growing crops. Erosion and changes in the form of river banks may be measured by inserting metal rods into the bank and marking the position of the bank surface along the rods at different times. [111][112] Crop residues play a role in the mitigation of erosion, because they reduce the impact of raindrops breaking up the soil particles. Meaning of soil erosion. Les dossiers thématiques du CSFD. The slope of the land. Soil erosion can lead to a loss of agricultural land and if unchecked, eventually results in desertification. erosion noun [U] (NEGATIVE EFFECT) C2 the fact of a good quality or situation being gradually lost or destroyed: The survey reveals a gradual erosion of the president's popularity and support. Another word for erosion. What does soil erosion mean? Living organisms - Small animals, insects, and worms can add to erosion by breaking up the soil so it is easier for the wind and water to carry away. In the earliest stage of stream erosion, the erosive activity is dominantly vertical, the valleys have a typical V cross-section and the stream gradient is relatively steep. 10. [113] There is a higher potential for erosion when producing potatoes than when growing cereals, or oilseed crops. In some cases, the slump is caused by water beneath the slope weakening it. Silt can smother the spawning beds of fish, by filling in the space between gravel on the stream bed. climatology, hydrology, geology, soil science, agriculture, chemistry, physics, etc.) Global studies continue to be based on the USLE[103], The most effective known method for erosion prevention is to increase vegetative cover on the land, which helps prevent both wind and water erosion. the Rangeland Hydrology and Erosion Model [102]) abandoned usage of USLE elements. Proper usage and audio pronunciation (plus IPA phonetic transcription) of the word soil erosion. Soil erosion may be a slow process that continues relatively unnoticed, or it may occur at an alarming rate causing a serious loss of topsoil. This is a serious problem for farmers. The type of soil moreover affects the potentiality of the occurrence of soil erosion. Rainfall, and the surface runoff which may result from rainfall, produces four main types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion. 42 p, greater than the rate at which water can infiltrate, preventative and restorative strategies for erosion, "Short-Term Impacts of Livestock Grazing on Vegetation and Track Formation in a High Mountain Environment: A Case Study from the Himalayan Miyar Valley (India)", "Hysteretic sediment fluxes in rainfall-driven soil erosion: Particle size effects", "Hydraulics and erosion in eroding rills", "Modern Erosion Rates and Loss of Coastal Features and Sites, Beaufort Sea Coastline, Alaska", "Hydroclimatology of wind erosion in arid and semi-arid environments", https://infosys.ars.usda.gov/WindErosion/Symposium/proceedings/jefferso.pdf, "Hillside processes: mass wasting, slope stability, and erosion", "Assessing the effects of land use and topography on soil erosion on the Loess Plateau in China", "Soil erosion and agricultural sustainability", "Countries and the global rate of soil erosion", "Soil movement by tillage and other agricultural activities", "Channel and habitat change downstream of urbanization", "Second Assessment Synthesis of Scientific-Technical Information relevant to interpreting Article 2 of the UN Framework Convention on Climate Change", "Impact of climate change on soil erosion and the efficiency of soil conservation practices in Austria", "Runoff and soil loss responses to changes in precipitation: a computer simulation study", "Expected climate change impacts on soil erosion rates: A review", "Towards estimates of future rainfall erosivity in Europe based on REDES and WorldClim datasets", "Land use and climate change impacts on global soil erosion by water (2015-2070)", "Soil-erosion and runoff prevention by plant covers: a review", "Global food crisis looms as climate change and population growth strip fertile land", Africa may be able to feed only 25% of its population by 2025, "Global rainfall erosivity assessment based on high-temporal resolution rainfall records", "An assessment of the global impact of 21st century land use change on soil erosion", "Impacts of agriculture on aquatic ecosystems in the humid United States", "Sustainable development of water resources", "African Dust Called A Major Factor Affecting Southeast U.S. Air Quality", "Robotic Observations of Dust Storm Enhancement of Carbon Biomass in the North Pacific", "Scaling soil erosion models in space and time", "Soil erodibility in Europe: A high-resolution dataset based on LUCAS", "A New European Slope Length and Steepness Factor (LS-Factor) for Modeling Soil Erosion by Water", "Estimating the soil erosion cover-management factor at the European scale", "Modelling the effect of support practices (P-factor) on the reduction of soil erosion by water at European scale", "Validation of field-scale soil erosion models using common datasets", "Evaluation of field-scale and catchment scale soil erosion models", "The G2 erosion model: An algorithm for month-time step assessments", "The creation of cultivable land through terracing", "Windbreaks, hedgerows, and woodland corridors", "Global perspectives on birds in agricultural landscapes", "Carbon sequestration potential of agroforestry practices in temperate North America", "Cover Crops for Conservation Tillage Methods", "The Advantages of the Fibrous Root & Taproot Systems", Soil erosion and agricultural sustainability.
