What is erosion plus erosion control methods
Erosion control guides? Soil erosion is a complex process that depends on soil properties, ground slope, vegetation, and rainfall amount and intensity. According to Montgomery, modifications in land use are one of the most impactful ways of accelerating soil erosion. These changes then have a cascade effect as the loss of fertile topsoil cover sends millions of tons of sediments into lakes and reservoirs, changing ecosystems and impacting agricultural production and water quality. This has been the case with the Bo River in Vietnam. Despite these types of soil erosion, as we have briefly mentioned above, if it wasn’t for human activities, today’s soils would be less susceptible to erosion and more resilient. What are the human causes behind soil erosion then?
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.
Sea wave erosion is accomplished primarily by hydraulic pressure, the impact of waves striking the shore, and by the abrasion (wearing, grinding, or rubbing away by friction) by sand and pebbles agitated incessantly by the water (see wave-cut platform). Wave impact and hydraulic action are usually most devastating to human-made coastal features such as breakwaters or moles. The impact and hydraulic action of storm waves are the most significant upon shores composed of highly jointed or bedded rock, which are vulnerable to quarrying, the hydraulic plucking of blocks of rock.

Soil erosion, that is, the process that transforms soil into sediments, is one of the major and most widely spread forms of land degradation (Lal 2014; Weil and Brady 2017). It encompasses the destruction of the physical structure that supports the development of plant roots. Moreover, surface soil removal may result in substantial nutrient and water losses, as well as in the decrease of productivity and the increase of pollution of surface waterways. Soil erosion impacts thus the sustainability of ecosystems and the provision of ecosystem services. Soil conservation efforts address concerns with these impacts and meet the increasing needs for food and raw materials (Hurni et al. 2008).
Green manures are a few different crops that can be grown, not for produce or food usage, but grown in order to fertilize the farmland on which it grows. This method can improve the soil structure and suppresses the growth of weeds. When water evaporates from the soil, it leaves behind its salt. This can lead to damage to soil and nutrient loss. Using humic acids can prevent this or growing crops like saltbush can rejuvenate the soils and replace lost nutrients. High levels of salt in the soil can often be caused by changes made to the water table by damming and other causes.
