River system: Geography of Rajasthan
RPSC RAS/RTS Mains Exam Practice/Mock/Solved/Test Papers in Both Hindi and English.
The Location of the great Indian watershed and the existence of the Aravalli axis greatly influence the drainage system of Rajasthan. The drainage to the Bay of Bengal and the Arabian Sea gets divide due to the Great Indian watershed which runs along the Aravali axis from the Sambhar Lake southward to Ajmer. From here before proceeding towards the southwest of Udaipur city the line runs to southwest, a few kilometers east of Beawar and to Deogarh and Kumbhalgarh further extending to in the west, past Udai sagar and runs to southeast to Bari Sadri, from Choti Sadri to Pratapgarh.
Smaller streams and their tributaries drain the west and south of the Aravalli axis. Rivers Luni, Sukri, Banas, Sabarmati and Mahi are most significant. These streams are non-perennial in nature. On the eastern side of the watershed, the river Chambal is joined by the river Banas along with its main tributaries like Khari, Moshi and Morel on the left bank and Berach, Bajasen and Golwa on the right. The river Chambal ultimately joins the river Yamuna in Uttar Pradesh.
The inland drainage system is the most characteristic feature of the drainage system of Rajasthan which is that nearly 60.2 per cent of the area of the state. Nearly all this area lies west of the Aravalli range. In this part Kanti basin, Sota and Sahibi basin, Barrah basin of the Luni basin are found in large number of separate drainage basins. The desert tract in the western part soaks all the water of these rivers.
The river Luni which rises at Ana Sagar at Ajmer is the only significant water course in this area is and flows towards the southwest for a distance of about 32 km through the districts of Jodhpur, Barmer and Jalore in the semi-arid tract west of the Aravalli range., the river has a small catchment area of about 32 sq km at the source at Talod Road. A small tributary joins from the Pushkar valley and the basin of the river widens. Near Ajmer, the river flows down the Aravalli slope and after 10km flows towards the southwest. This river drains the total catchment area of about 34,866.40 sq kilometers. As it is a rain-fed stream the river is choked with advancing sands at many places during the dry season. When the river is carrying maximum water during the monsoon season it is not able to cut the Aeolian deposits. It receives many smaller hill torrents from the western slope of the Aravalli range, like Lalri, Ghuhia, Bandi, Sukri, Jawai, Jojri and Sagai, all joining on the left bank. All these streams contribute to the sub-soil within its bend. Up to Balotra the water of river Luni but lower down it becomes more and more saline till the river drains near the Rann of Kutch. The river Luni increases in width at Jodhpur district rather than deepening the bed. This is because the floods develop so quickly due to the nature of rainfall that the river has no time to rub the bed. The River Luni spills over the country and occasionally damages the railway line to which it actually runs parallel from Luni Junction to Gole during the rainy season.
The southern and the eastern part of Rajasthan, south, southeast and east of the Aravalli range receives more than 80 cm rainfall and has some important streams.
The river Chambal is the largest stream and is joined by some tributaries like the Banas, the Kali Sindh, and the Parbati. The river Chambal is a perennial river while its tributaries might occasionally turn completely dry and exhibit their stony beds.
The river Chambal rising from the northern flanks of the Vindhyan scarps near Manpur (884.4 m) in the south of Mhow runs for about 325 km through a long narrow and steep gorge which overhangs the valley on both the sides rising about 60m to 90 m above the valley floor. The river falls at 505 m near Chaurasigarh to Kota.
The river Chambal is joined by its first major tributary – river kali Sindh near Monera village. Another tributary Parbati joins about 48 km downstream. Taking a straight course for about 212 km, it bends southeast at Pinahat and flows to join the river Yamuna near Murad ganj, after a total run of about 965 kilometres. For a length of about 153 km the river flows entirely in Rajasthan. The river forms the boundary between Rajasthan and Madhya Pradesh from Palia to Pinahat for about 241 km. it forms the boundary between Madhya Pradesh and Uttar Pradesh Before joining the river Yamuna in Uttar Pradesh. In Rajasthan two other tributaries Kurai and Banas join the Chambal River on the left bank.
The Banas River flows through the heart of the Mewar Plains. Its chief tributaries are Berach, Kothari, Khari, Dhoond and Morel. The river Banas rises from the catchment area lying between Kankroli and Nathdwara and flows towards the east as far as Mandalgarh and further it flows towards the northeast up to Tonk where it again turns towards the east and finally this river turns at right angles and flows south to join the river Chambal. The upper reaches of this stream are hilly and have good rainfall.

Sarasvati and Drishadvati: Ancient Indian River
(O Sarasvati, you the best of mothers, the best of rivers, the best of gods! Although we are of no repute, mother, grant us distinction.)
During the vedic civilization, Aryans developed Rigveda, which describes about the ” Sapta Sindhu ” the seven rivers of NW India , traced from east to west as Sarasvati, Satadru ( Sutlej ), Vipasa (Beas), Parosni (Ravi) , Asikni (Chenab) Vitasta (Jhelum) and Sindhu (Indus) which started flowing consequent on the melting of the Himalayan glaciers at the end of Pleistocene.
Sarasvati River system is sequenced as Sutlej-Markanda-Drishadvati-Ghaggar-Hakra river channels which constituted the hydrological flows of Vedic Sarasvati River system traceable upstream: from
- Sarasvati creek starting from Ad Badri at the foothills of the Siwalik ranges and Extending into the Bata Valley in upper reaches of the Himalayas, traceable into the Rupin-Supin glaciers close to Yamunotri glaciers.
- Another glacier source from ManaSarovar yielded the River Sutlej which was a tributary of Vedic Sarasvati River System joining the latter southwards from Ropar at Shatrana (50 km. South of Patiala).
