Erosion is the mechanism of the detachment of the soil and other materials from the earth surface i.e. Weathering away of the land. The erosion Is the result of complex and interrelated natural processes which would loosen and move away the soil and rock material under the action of water, wind and other ecological factors. To this list, human activities like mining, excavation of building and highways, etc. are also added. The long term effect of erosion is the removable of the soil and rock particles from exposed surface, their transport to lower elevations and eventual deposition. Erosion can be classified as natural process and human induced process. The soil erosion caused by water can be distinguished into four forms sheet, rill, gully and channel erosion. a. Sheet erosion: detachment of material from land surface by land drop impact. b. Rill erosion: when sheet erosion is allowed, it will form minute finger shaped groves over the entire field, such thin channeling is known as rill erosion. c. Gully erosion: when rill erosion is neglected, the tiny develop into wider and deeper channels which are called gullies. d. Channel erosion: it is removable of material (soil contents) by concentrated flow. In case of Nepal, It is very prone to soil erosion and is susceptible to 'sediment disasters mainly caused by slope failure, landslides, debris flows and bank erosion. Productivity of the land is deteriorating due to accelerated surface soil erosion in different part of the country. What’s the condition in your region or country and what different approaches should be made to combat soil erosion, share with me in comment section. |
