Become a Study.com member to unlock this 4, pp. Of course, winter is also the stormy season in many locations, so wind and rain are available to wash soil away. Depending on the duration and intensity of a rainfall, soils can exhibit signs of one of the four forms of the damage, including: Climate is a major driver of erosion, however changes in land use and land cover – due to development and land management – can dramatically affect exposure of sediments to erosion. What are the difference between Japanese music and Philippine music? 1. Deforestation causes soil erosion. When did organ music become associated with baseball? The problem may become so severe that the land can no longer be cultivated and must be abandoned. The raindrops disperse the soil, which is then washed away into the nearby streams and rivers. Regions with very heavy and frequent rainfall face a large amount of soil loss. What was decided after the war about the re-building of the chathedral? Farmers remove native vegetation and then plow the land to plant new seeds. All rights reserved. Soil erosion is a problem in many developed as well as developing nations, and most of the time this problem is caused due to bad or poor farming techniques and methods. During heavy rains, soil erosion is common. Conservation Measures 9. Here are some of the ways that water causes erosion: Rainfall – Rainfall can cause erosion when the rain hits the surface of the Earth. Causes of Soil Erosion. Whyte (1957) while commenting on the problem of soil erosion of Kashmir Himalayas, mentioned, “control of fluctuating grazing was made the responsibility of forest department in 1939 but this appears to have little effect and the problem is as acute as ever”. Additionally, after periods of drought, the soil can be too dry to sufficiently absorb the water in the short term (due to the lack of cohesion). The severity of water erosion is influenced by slope, soil type, soil water storage capacity, nature of the underlying rock, vegetation cover, and rainfall intensity and period. Rainfall - Rainfall can cause erosion both when the rain hits the surface of the Earth, called splash erosion, and when raindrops accumulate and flow like small streams. As mentioned, the predominant causes of soil erosion are either related to naturally-occurring events or influenced by the presence of human activity. Soil erosion in conventionally tilled field Tillage and cropping management systems are critical components for reducing raindrop impact on soil particles due to the availability of crop residue to protect the soil surface. Forms of Water Erosion 3. Once soil erosion occurs, it is more likely to happen again. All Rights Reserved. Erosion degrades land, which means it can support fewer plants that can take in climate-warming carbon dioxide. It is now established that collision of rain drops on bare soil and resulting splash is the major cause of soil erosion by water. With sheet erosion, usually caused by direct rainfall, soil materials are removed uniformly from the top layer. Erosion by Water. - Causes, Types & Prevention, What is a Landslide?
