Ravines of Rajasthan
Ravines form a significant topographical feature of the Chambal valley and the most serious surfacial problem of the area. It is felt that unscientific land practices and dissection of the older river terraces by gullying process, perhaps due to neo-tectonic upliftment, contribute simultaneously to the formation of ravines which are present in the whole of the Chambal belt. The intensively affected areas are found along the main rivers in the districts of Kota and Bunch.
About a hundred thousand hectares of land in the Chambal valley in Rajasthan falls under ravines. It ranges from 10,000 to 50,000 hectares along its tributaries. Districtwise, Kota has 124.600 hectares of land under ravines, Bunch has 86,000 hectares and Jhalawar 6,900 hectares. Their depth varies from about a metre to four metres. Very deep ravines are completely useless for cultivation.
