Rivers of Rajasthan

Major rivers of Rajasthan

Remembering origin and flow direction is the single most-asked point in REET on this topic.[Source 1]

East-flowing and west-flowing rivers

The Aravalli range acts as a watershed for Rajasthan's rivers. Rivers flowing east of the Aravallis — Chambal, Banas, Mahi — eventually join the Bay of Bengal or the Gulf of Khambhat, while the Luni, which flows west of the Aravallis, tries to head towards the Arabian Sea but disappears into the marshy part of the Rann of Kutch without ever reaching the sea.

This is why the Luni is classed under 'inland drainage'. While teaching EVS it's useful to explain to children that a river's 'origin' and 'where it eventually joins' are two separate facts, which are often confused.

The Chambal river and dam projects

The Chambal is the only Rajasthan river that flows all year round, which is why it's called a 'perennial' river. Multipurpose dam projects such as Gandhi Sagar, Rana Pratap Sagar and Jawahar Sagar have been built on it in the Kota region, useful for both irrigation and hydroelectric power.

The Banas is often called 'Rajasthan's own river' because it flows entirely within the state's boundaries and eventually joins the Chambal. The Kothari, Khari, Dai, Gambhiri and Bedach are its major tributaries.

Other notable rivers

Besides the major rivers above, Rajasthan also has some smaller rivers that are geographically noteworthy. The West Banas — a separate, smaller river originating in southern Rajasthan (Sirohi region) and flowing towards Gujarat — should not be confused with the main 'Banas river' (a tributary of the Chambal), because although their names are similar, they are entirely different rivers.

Small tributaries such as Kothari, Khari, Dai, Gambhiri and Bedach may be asked less often in the main exam, but mentioning them helps in understanding that any major river system includes many smaller tributary streams in addition to the main river, together keeping the whole water system balanced.

Eastern Rajasthan Canal Project (ERCP) and river-linking

To address the shortage of water for drinking and irrigation in several eastern Rajasthan districts (such as Jhalawar, Kota, Bundi, Tonk, Sawai Madhopur, Alwar and Bharatpur), the Eastern Rajasthan Canal Project (ERCP) has been conceived, aimed at using surplus rainwater from the tributaries of the Chambal basin (such as Kalisindh, Parvati and Kuno) in water-scarce districts.

In this direction, Rajasthan and Madhya Pradesh have agreed on the 'Parvati-Kalisindh-Chambal river-linking project', considered an important step under the country's river-linking plan. Such projects show that water management remains one of Rajasthan's biggest priorities today, and that knowledge of rivers isn't limited to geography — it connects to current policy too.

Rivers, civilisation and irrigation projects

The importance of rivers isn't limited to geography — they have also been the foundation for settlement by ancient civilisations. Kalibangan, in Hanumangarh district, located on the banks of the Ghaggar river (which is also linked by some to the ancient Saraswati river), is an important archaeological site of the Indus Valley Civilisation, where the earliest evidence of a ploughed field has been found. This example is useful for teaching children the historical relationship between rivers and human settlement.

In modern times, the Bisalpur Dam has been built on the Banas river, located in Tonk district, and is a major source of drinking water for the cities of Jaipur, Ajmer and Tonk. Rivers thus continue to play a central role in irrigation as well as urban drinking-water supply, especially in a low-rainfall state like Rajasthan, where every water source is considered precious.

While teaching EVS, presenting rivers not just as a line on a map but as a source of life, agriculture and drinking water develops a sense of respect for the environment in children.
