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?
Rainwater also mixes with chemicals as it falls from the sky, forming an acidic concoction that dissolves rock. For example, acid rain dissolves limestone to form karst, a type of terrain filled with fissures, underground streams, and caves like the cenotes of Mexico’s Yucatan Peninsula. Back up on the mountains, snow and ice build up into glaciers that weigh on the rocks beneath and slowly push them downhill under the force of gravity. Together with advancing ice, the rocks carve out a path as the glacier slumps down the mountain. When the glacier begins to melt, it deposits its cargo of soil and rock, transporting the rocky debris toward the sea.
The abrasive action of sand and pebbles washed against shorelines is probably the most significant wave erosional activity. Particles are dragged back and forth by wave action, abrading the bedrock along the coast and abrading each other, gradually wearing pebbles into sand. Wave erosion creates retrograde, or retreating, shorelines with sea cliffs, wave-cut benches at the base of the sea cliffs, and sea arches—curved or rectangularly shaped archways that result from different rates of erosion due to varied bedrock resistance. Besides the back-and-forth transportation of materials by wave action, sediments are transported by the lateral movement of waves after they wash ashore (beach drifting) or by shallow-water transport just offshore, known as longshore currents. These transportational movements lead to deposition and the formation of prograde, or advancing, shorelines, bars, spits, bayhead beaches (a bayhead beach is formed between two headlands), and barrier beaches (a barrier beach parallels the shore).

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.
Construction sites use a number of materials, including wood lumbar, metal, and toxic chemicals. Both wind and water erosion can carry particles of those materials to nearby areas, creating a number of problems for society. Both erosion and sedimentation are major contributors to water pollution in a particular area. Erosion is the process of soil, rock, or other particles becoming removed from one place and carried to another location by natural forces such as wind or water. As an aftereffect, sedimentation occurs when certain particles settle at the bottom of storm drains or rivers. Unfortunately, that excess amount of water can spread pollutants and increase the potential for flooding.
