All on erosion, a full guide

What is erosion plus erosion control strategies? What is soil erosion and soil degradation? Although soil erosion is a natural process, human activities over the past decades have greatly accelerated it. In fact, according to the UNESCO, land degradation is undermining the well-being of two-fifths of humanity, driving species extinct and intensifying climate change. According to a senior UN official, all of the world’s topsoil could be gone within 60 years.

Every year, rivers deposit millions of tons of sediment into the oceans. Without the erosive forces of water, wind, and ice, rock debris would simply pile up where it forms and obscure from view nature’s weathered sculptures. Although erosion is a natural process, abusive land-use practices such as deforestation and overgrazing can expedite erosion and strip the land of soils needed for food to grow.

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. Find additional details on website.

The cover-management factor (C-factor) within the Revised Universal Soil Loss Equation (RUSLE) is used as an indicator of soil protection by different land-uses and management options (Renard et al. 1991). Yet, few studies have addressed its potential as a dynamic tool for erosion control (Panagos et al. 2015b). Experimentally determined values for the C-factor for most land uses and management systems are easily found in the literature (e.g., Pimenta 1998a). Moreover, both remote sensing and geographical information systems (GIS) techniques can be efficiently used to estimate the C-factor at landscape level (Wang et al. 2003; Lu et al. 2004; Durigon et al. 2014). Nevertheless, the literature does not report the use of the C-factor to address impacts of vegetation density changes over time under the same land use or management type. This provided the motivation for this research.

Why Is Erosion Control Important? Without erosion control, your topsoil may lose its ability to hold nutrients, regulate water flow, and combat pollutants. In addition to affecting the ecosystem of nearby wildlife, residential properties and transportation systems can suffer long term damage. To combat the environmental problem of both erosion and sedimentation, certain methods must be practiced by construction companies.
