rajasthan gk in english:Plains of Rajasthan Part-1

There are several plains in Rajasthan and unlike the Great Plain of India, each one of them varies in physical characteristics. They are : 1. Sandy Arid Plain or Marusthali, 2. Luni Basin or Godwar Tract, 3. Plain of Interior Drainage or Shekhawati Tract (Bagar), 4. Banas Plain, 5. Bharatpur Plain, 6. Harauti Plain, 7. Chappan Plain, and 8. Ghaggar Plain. The plains mentioned at serial number 1, 2 and 3 above, form parts of Thar desert. 

The Banas Plain also termed as Mewar Plain, is a dissected plain on Acchaean gneiss and covers the eastern part of Udaipur, western Chittaurgarh, Bhilwara, Tonk, Jaipur, western Sawai Madhopur and southern part of Alwar. This area from a maximum height of 582 m in Deogarh, slopes gradually towards the east and northeast from the eastern foot of the Aravali Range and is drained by the Banas and its tributaries. The alluvial deposits are scanty towards the west and thick in the east covering large parts of Kishangarh burying most of the gneissic rocks of which the plain is made. 

This is a saucer like plain akin to the Yamuna plain, Bharatpur city being at its centre. Possibly it is the lowest part of the State. Through the landset imageries and the aerial photographs it has been recently discovered that the old channel of the Yamuna passes through Bharatpur district. Thus it is an alluvial flat plain deeply silted by both the present and past rivers. During the monsoon period if the rains persist for more than 3-4 days, the lower parts of the plain are flooded. However, the floods spread new alluvium over the cultivated areas and provide fertility to the plain. Since these floods are created by the waters flowing from Haryana and the Uttar Pradesh streams, besides the rivers of Rajasthan and there is colossal loss from year to year, large number of tanks have been built by damming the channels, and the rivers are being drained and diversion canals are being built by the Governments of the three concerned States.
