| | Erosion - Wikipedia, the free encyclopedia |
 | | Splash erosion is the detachment and airborne movement of small soil particles caused by the impact of raindrops on soil. | | | Windbreaks are often planted by farmers to reduce wind erosion. | | | 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. |

| | Erosion transports rocky material after the process of weathering has broken bedrock down into smaller, moveable pieces. | | | Erosion, removal of rock and soil material by natural processes, principally running water, glaciers, waves, and wind. | | | When an area receives more water (in the form of rain, melting snow, or ice) than the ground can absorb, the excess water flows to the lowest level, carrying loose material with it. |

| | The Problem of Wind Erosion |
| | Wind erosion is also a serious problem on cultivated organic soils, sandy coastal areas, alluvial soils along river bottoms, and other areas in the United States. | | | Lyles (1975) estimated that top soil loss from wind erosion causes annual yield reductions of 339,000 bushels of wheat and 543,000 bushels of grain sorghum on 0.5 million hectares (1.2 million acres) of sandy soils in southwestern Kansas. | | | Blowing soil impacting plants can also reduce seedling survival and growth, depress crop yields, lower the marketability of vegetable crops, increase the susceptibility of plants to certain types of stress, including diseases, and contribute to transmission to some plant pathogens (Armbrust, 1982 and 1984; Claflin, et al., 1973; Michels et al., 1995). |

| | Reclamation grasses are used in areas where erosion control and stabilization of the ground is a necessity. | | | Erosion control is needed now more than ever with increased land clearing not for farms but homes, shopping centers, roadsides, landfill, reclamations sites of all kinds. | | | Almost any plant can be used for erosion control; the most prevalent problem is choosing a coverage that grows fast and is adaptable to the area. |

| | coastal erosion - Hutchinson encyclopedia article about coastal erosion |
| | Beach erosion can occur due to the construction of artificial barriers, such as groynes, or due to the natural high tides and high waves during winter storms, which tend to carry sand away from the beach and deposit it offshore in the form of bars. | | | In other places, if erosion is rapid but transport is limited, material builds up, and a low-angle slope develops. | | | Weaknesses in the limestone, such as faults and joints, have been exploited by forces of erosion and mass wasting (downslope movements of loose materials such as sand). |

| | soil erosion |
| | Erosion results in the loss of valuable soil and its nutrients that are necessary for crops to grow. | | | Erosion is a process that removes soil layers and carries them away from farmer's fields to bodies of water or other land. | | | Although water and wind erosion are caused primarily by natural elements, the farmer's tillage practices are also important. |

| | Soil Erosion |
| | On commercial farm lands, overstocking, mono-cropping, and the ploughing of marginal lands unsuitable for cultivation has led to soil erosion and desertification. | | | * plants in wetlands and on the banks of rivers are of particular importance as they slow down the flow of the water and their roots bind the soil, thus preventing erosion. | | | The intensive agriculture and overgrazing that followed caused greater degradation. |

| | Erosion |
| | The amount of erosion that occurs is dependent on two factors: size of soil particle (it is easier to move a grain of sand than a boulder) and speed of erosive force (wind/water). | | | In short, erosion is the movement of soil particles by wind and water. | | | Since we have no control on the size of soil particle, this factor is measured and accepted as a characteristic of the area. |

| | Erosion |
| | Erosion is a natural process that causes a gradual wearing away of land surfaces by water, ice and wind. | | | Restore or plant deep-rooted vegetation along the strip leading to the retaining wall; this will help buffer surface water from runoff and reduce the risk of erosion by holding the soil together. | | | These areas are also often transition zones - the “vital edges” where land and water meet to create unique and often highly productive ecosystems. |

| | Soil Erosion Winding Down, Not Revving Up (August 23, 1999) -- Fertile topsoil is probably not eroding from farmlands at the alarming rate that it's widely believed to be, suggests a study in the 20 August issue of Science. | | | Soil and rock particles derived from the glacial, riverine, and agricultural erosion of east-central North America enter the Gulf of Mexico as muddy water along the delta of the Mississippi River. | | | Natural processes operate over areas larger than those affected by agriculture and construction, but even taking that into account, "the bottom line is, we move about 10 times as much sediment as all natural processes put together," he said. |

| | When we remove vegetation or other objects that hold soil in place, we expose it to the action of wind and water and increase its chances of eroding. | | | Nature slowly wears away land, but human activities such as construction increase the rate of erosion 200, even 2,000 times that amount. | | | This soil carries with it pollutants such as oil and grease, chemicals, fertilizers, animal wastes and bacteria, which threaten our water quality. |

| | Most have been developed for agricultural areas and are design to compare predicted annual rates of soil loss from broad areas under various cropland and rangeland management techniques. | | | Designers of constructed landforms, however, have considerable control over the topography, cover soil placement, initial revegetation, and to a lesser extent the substrate properties – flexibility that is generally uneconomical for farmers and ranchers and most users of erosion models. | | | Aside from a few new deterministic gully erosion models, these models do not consider gully erosion – mostly due to difficulties in modelling, and partly because gullies are often repaired in agricultural, forestry, or mining environments. |
