As a result, the soil structure gets impoverished. On sloping lands, all tillage operations should be done at right angles to the slope of the land. But sometimes, road and rail embankments come in the way of natural drainage channels.
These gulleys are known by different names—khars in Gujarat, Maharashtra and Karnataka; ravines in Madhya Pradesh, Uttar Pradesh and Rajasthan along Yamuna and Chambal; kotar lands in Gujarat and chos the rainy season torrents and landslides in Hoshiarpur in the Shivaliks.
At an advanced stage, gullies result in ravines, which are sometimes 50 to feet deep. Rajasthan, Maharashtra and Punjab, upto 15 per cent of the total land suffers from soil erosion. Erodability of the soil is influenced Research thesis on soil erosion the nature of the soil, particularly its texture, structure, organic matter, amounts and kinds of salts present, presence of hard pan in the soil and presence of high water table.
Besides, demand for land for providing social priorities such as shelter, roads, industrial activities is increasing at a very fast rate with the rise in population and very often good agricultural and forest lands are being diverted to such use. For instance, in the Nilgiris, land has been opened for cultivation of tuber crops like potatoes and ginger without undertaking anti-erosive measures like terracing of slopes.
Improving the Existing Surface Cover: The period of heavy downpours from August to October is the period of the heaviest erosion in these regions.
The presence of high water table checks the infiltration and permeability, thus allowing more flow of water on the surface, and greater erosion.
This can be done by resorting to cover cropping by growing groundnut or berseem a fodder crop or through grasslands development by growing grasses like dub, kudzu, pans and dinanath. When sheet erosion continues unchecked, the silt laden run-off forms well-defined minute finger shaped grooves over the entire field.
These measures can be biological or mechanical Fig. One such example is Brahmaputra river which has been exposed to siltation because of large-scale deforestation in the hills, and the floods in Brahmaputra valley have become an annual phenomenon now.
An extreme example of soil erosion is to be seen in sand movement from the coast in the Saurashtra region of Gujarat, where the once flourishing ports are now covered with advancing sand-dunes.
This type of erosion is caused by the striking action of strong waves. Lack of Proper Surface Drainage: Sheet erosion is more or less universal on:Download thesis statement on Soil Erosion in our database or order an original thesis paper that will be written by one of our staff writers and delivered according to the deadline.

soil erosion essaysSoil erosion is a gradual process that occurs when the actions of water, wind, and other factors eat away and wear down the land, causing the soil to deteriorate or disappear completely. Soil deterioration and low quality of water due to erosion and run off has often become a sev.
