Everything on erosion, a full guide? The most effective way of minimizing erosion is to guarantee a permanent surface cover on the soil surface, such as trees, pasture, or meadow. However, compared to original forest soils, soils in pasture fields and croplands have less capacity to hold up and are more susceptible to erosion. These soils also have less capacity to absorb water, which makes flooding (and its economic, social, and environmental impacts) more common. The increasingly high demand of a growing population for commodities such as coffee, soybean, palm oil or wheat is clearing land for agriculture. Unfortunately, clearing autochthonous trees and replacing them with new tree crops that don’t necessarily hold onto the soil increases the risks of soil erosion. With time, as topsoil (the most nutrient-rich part of the soil) is lost, putting agriculture under threat.
Water is nature’s most versatile tool. For example, take rain on a frigid day. The water pools in cracks and crevices. Then, at night, the temperature drops and the water expands as it turns to ice, splitting the rock like a sledgehammer to a wedge. The next day, under the beating sun, the ice melts and trickles the cracked fragments away. Repeated swings in temperature can also weaken and eventually fragment rock, which expands when hot and shrinks when cold. Such pulsing slowly turns stones in the arid desert to sand. Likewise, constant cycles from wet to dry will crumble clay.
In rivers and estuaries, the erosion of banks is caused by the scouring action of the moving water, particularly in times of flood and, in the case of estuaries, also by the tidal flow on the ebb tide when river and tidewater combine in their erosive action. This scouring action of the moving water entrains (that is, draws in and transports) sediments within the river or stream load. These entrained sediments become instruments of erosion as they abrade one another in suspended transport or as they abrade other rock and soil as they are dragged along the river bottom, progressively entraining additional sediments as long as the river’s volume and velocity of the stream continues to increase. As the velocity of the river decreases, the suspended sediments will be deposited, creating landforms such as broad alluvial fans, floodplains, sandbars, and river deltas. The land surface unaffected by rivers and streams is subjected to a continuous process of erosion by the action of rain, snowmelt, and frost, the resulting detritus (organic debris) and sediment being carried into the rivers and thence to the ocean.

Local climate change scenarios will contribute to water erosion processes, mostly by rainfall erosivity increase. Different forest management models provide varying levels of soil protection by trees, resulting in distinct soil loss potential. Results confirm the suitability of the proposed approach to address soil erosion concerns in forest management planning. This approach may help foresters assess management models and the corresponding silvicultural practices according to the water-related services they provide.
Erosion is a top concern for construction sites around the world. In addition to posing a threat to the environment, erosion can pollute surrounding rivers and bodies of water, putting both wildlife and human health at risk. That being said, there is a high need for erosion control measures for construction sites. As a manager in your business, it’s important for you to be prepared to adequately prevent erosion in your area.
