What is erosion with erosion control information? Soil erosion is a gradual process of movement and transport of the upper layer of soil (topsoil) by different agents – particularly water, wind, and mass movement – causing its deterioration in the long term. In other words, soil erosion is the removal of the most fertile top layer of soil through water, wind and tillage. What Is Soil Erosion? A Soil Erosion Scientific Definition: According to a Pereira and Muñoz-Rojas (2017) synthesis, soil erosion is one of the major causes, evidence of, and key variables used to assess and understand land degradation. Soil erosion is a consequence of unsustainable land use and other disturbances, such as fire, mining, or intensive agricultural uses. The loss of soil may have serious impacts on the quantity and quality of soil ecosystem services, with serious economic, social, and political implications.

Bits of sand are picked up and carried off by the wind, which can then blast the sides of nearby rocks, buffing and polishing them smooth. On the seashore, the action of waves chips away at cliffs and rakes the fragments back and forth into fine sand. Plants and animals also take a heavy toll on Earth’s hardened minerals. Lichens and mosses can squeeze into cracks and crevices, where they take root. As they grow, so do the cracks, eventually splitting into bits and pieces. Critters big and small trample, crush, and plow rocks as they scurry across the surface and burrow underground. Plants and animals also produce acids that mix with rainwater, a combination that eats away at rocks.

Glacial erosion occurs in two principal ways: through the abrasion of surface materials as the ice grinds over the ground (much of the abrasive action being attributable to the debris embedded in the ice along its base); and by the quarrying or plucking of rock from the glacier bed. The eroded material is transported until it is deposited or until the glacier melts. In some arid and desert tracts, wind has an important effect in bringing about the erosion of rocks by driving sand, and the surface of sand dunes not held together and protected by vegetation is subject to erosion and change by the drifting of blown sand. This action erodes material by deflation—the removal of small loose particles—and by sandblasting of landforms by wind-transported material.

We aim at assessing the impacts of forest ecosystem management practices (e.g., selection of tree species, harvesting) on soil protection, as its planning schedule impacts soil erosion over the long-term (Lu et al. 2004; Panagos et al. 2014, 2015b). Our research examines how management practices contribute to change the vegetation cover over time. It further encapsulates these changes within the RUSLE, by determining the corresponding C-factor. Seven stand-level forest management models (sFMM), i.e., sequences of management practices, with species-specific rotations, over a 90-year time span, are used for testing purposes. Specifically, we assess and compare sFMM according to their potential for the provision of water-related ecosystem services under two climate scenarios.

Terracing is a method of carving multiple, flat leveled areas into hills. Steps are formed by the terraces which are surrounded by a mud wall to prevent runoff and hold the soil nutrients in the beds. More commonly found in lesser developed nations due to the difficulty of using mechanized farming equipment in the terraces. Very popular in Asia for planting rice. A more enhanced version of Contour Plowing, maximum water retention is achieved by taking into account all the watershed properties when making the contour lines. The Keyline refers to topographic features linked to water flow. This allows the water to run off to run directly into an existing water channel, and prevent soil erosion caused by the water.
