Educational

Main ideas / lessons (Rajasthan Geography – Rivers, Part 6; focus on Banas and related rivers)

  • The session is part of a free RWS TET/Computer Instructor preparation batch run on the RWA State Exam YouTube channel.
  • It continues the river study from Part 5, focusing first on the Banas River, and then on several rivers that feed into the Banas system. Later, it shifts to Chambal-related rivers such as Parvati, Kalisindh, Chandrabhaga, Banganga, etc.
  • The instructor emphasizes exam-oriented facts, including:
    • Origin points
    • Course through districts
    • Where tributaries meet
    • Dams and civilization sites located on these rivers
    • Special types of confluences (e.g., Triveni Sangam) and which rivers create them
    • MCQ-relevant nuances, such as river length and flow-order / flow classification

Detailed “must-remember” exam points

1) Banas River (Banas / Vanasa / Varnayaasa / Vishthi River)

Basic origin (commonly asked)

  • Origin is from Khamnor / Kumbhalgarh hills, Rajsamand.

Exact-origin nuance (how questions may be framed)

  • If the exam asks for a very specific start point, the answer depends on the river’s start relative to:
    • Bairok(i) Math / Khamnor hill / Kumbhalgarh (Rajsamand)
  • The instructor repeatedly distinguishes between:
    • “Common origin” vs “exact location wording”

Total length

  • 512 km
  • Note: H.M. Saxena mentions 480 km.

Districts through which Banas flows (6 total)

  • Rajsamand, Chittorgarh, Bhilwara, Ajmer, Tonk, Sawai Madhopur

Where Banas joins Chambal

  • Banas joins Chambal River at Rameshwaram Dham (Sawai Madhopur).

Banas Basin (important terminology)

  • Banas Basin = districts in the catchment area of the Banas River.
  • Elevated/flat-raised mound-like areas in the basin are called:
    • Pindmat plains
  • The northeastern part of Banas Basin is called:
    • Malpura–Karauli plain

Major dams and civilization sites on Banas (as taught)

  • Bagheri Naka Dam (Rajsamand)
  • Nandasamand Dam (Rajsamand)
  • Gulund / Gilund civilization site (Rajsamand)

    • Supplies drinking water to southern Jaipur
  • Ishardha Dam (Sawai Madhopur)

Shape/flow character in Tonk

  • In Tonk, Banas takes a serpentine (snake-like) meandering shape.

Triveni Sangams on/within the Banas system

  • The instructor claims Rajasthan has 5 Triveni Sangams total, and 3 of them are on/within the Banas river system.
  • The 3 Triveni Sangams (as taught) are:

  1. Bigod (Bhilwara)

    • Bedach + Menal meet in/with Banas → Triveni Sangam

  2. Rajmahal (Tonk)

    • Dai + Khari meet in/with Banas → Triveni Sangam

  3. Devdham (Tonk / Jodhpur region mentioned)

    • Bandi + Mansi meet in/with Banas → Triveni Sangam
    • Instructor also refers to it as “Jodhpuriya Tonk.”

Tributaries list of Banas (as stated)

  • Bedach, Menal, Mansi, Morel, Dhundh, Dai, Khari, Sohadra, Kothari, Balganga

Right-side joining tributaries (direction-based MCQ)

  • Tributaries stated as joining from the right-hand side:
    • Bedach and Menal
  • All other listed tributaries join from the left side.

2) Bedach (Aayad) River (major Banas tributary)

Origin (hill)

  • Originates from Gogunda hill (Udaipur district).

Course and name-change logic

  • From Gogunda hill, the river flows and falls into Udai Sagar Lake.
  • After emerging from Udai Sagar Lake, its name becomes Bedach.

Where Bedach flows and meets Banas

  • Flows through Udaipur → Chittorgarh → Bhilwara
  • Joins Banas at Bigod (Bhilwara)

Civilization sites (as taught)

  • Ahar civilization site on the river when it is Aayad (before/around the Udai Sagar Lake stage)
  • Balathal civilization site on Bedach
  • Mentions Urban/Nagari civilization and Gosunda Dam on Bedach (in a Chittorgarh context)

3) Menal River (joins Banas; Triveni at Bigod)

  • Origin: Menal Mountain (in Bhilwara district)
  • Joins: Menal flows and joins Banas at Bigod
  • Triveni Sangam at Bigod: Bedach + Menal with Banas

4) Khari River (salty/saline river type explained)

Origin

  • Originates from Bijral village hills (Rajsamand).

Flow path (districts)

  • Rajsamand → Bhilwara → Beawar → Ajmer → Tonk

Join point with Banas

  • Joins Banas at Rajmahal (Tonk).

Triveni Sangam at Rajmahal

  • Dai + Khari + Banas form a Triveni Sangam at Rajmahal.

Dams on Khari (as taught)

  • Khari Dam (Bhilwara)
  • Narayan Sagar Dam (Beawar) (explained as part of the Khari system)

Flow-order classification nuance (MCQ style)

  • Instructor states there are multiple “Khari” rivers in Rajasthan with different flow directions:
    • From Sher village hills, Sirohi → Arabian Sea
    • From Bijral village hills, Rajsamand → Bay of Bengal
    • Another from Khandel (Sikar/Jaipur region) → internal flow order

5) Dai River (joins Banas at Rajmahal)

  • Origin: Nasirabad Hills (Ajmer)
  • Course: passes through Ajmer → Tonk
  • Join point: joins Banas at Rajmahal
  • Resulting confluence: Dai + Khari create Triveni Sangam with Banas at Rajmahal

6) Bandi River and Mansi River (combine at Devdham for Triveni Sangam)

Bandi River

  • Origin hills: Alamlod hills (in Samod, Jaipur as stated)
