The Arvari River, which originates in Aravalli range, is a small river flowing through the Alwar District of Rajasthan, India. It has a total length of 45 km (28 mi) and a total basin area of 492 km2 (190 sq mi).[1] Downstream of the Sainthal Sagar dam on Arvari, the Arvari river meets Sarsa River to become the Sanwan River. The Sanwan meets the Tildah and Banganga rivers to converge with the Gambhir (also known as the Utang river). Gambhir then converges with the Yamuna in Mainpuri district of Uttar Pradesh, Yamuna converges with Ganges at Triveni Sangam in Prayagraj.[2][3][4]
It is notable for having its flow restored after being dry for 60 years. This process began in 1986, and required the efforts of the people of the Bhanota-Kolyala village, with the help of Dr. Rajendra Singh. The villages that lay in the river's catchment area built earthen dams, with largest being 244 m long and 7 m wide. Following the construction of 375 dams, the river started to flow again, becoming a perennial river in 1995.[5] The Arvari River Parliament was formed in 1998 to help maintain the health of the river.
Origin
Key features are as follows:
- Total basin area: 492 km2
- Total Length of flowing river: 45 km
- Length of river: 35 km
- Total water structures: 402 [1]
The river Arvari originates in the Sakra Dam near Thanagazi in the Alwar District. The northern catchment area of the river is around Kankad ki dhani. Of the two sources of the river, one source originates from Bhairudev Public Wildlife Sanctuary near the village Bhavta Kaliyal (Bhuriyawas), the other near Amka and Jodhula. There is a third stream close to second source, which is lost into the ground. The two streams meet near Ajabgarh- Pratapgarh, at Palasana ka Pahad. From this point, the river is called Arvari and runs down to the village Hamirpur to meet Nahar Nala, a stream from the west.[6]
Drainage
Another tributary, the Bidila river, originates in Jamwa Ramgargh, Jaipur, and augments the Arvari. The augmented river joins an equally large tributary originating around Lothabas in the west near Romewala, then passing through the Jaitpur Gujrun, Rasayawala and Rayanwala regions. Here, the Aravari becomes large enough to feed its own reservoir, Sainthal Sagar, which was formed by a large dam on the same river. Following the dam, the Arvari river meets Sarsa to become the Sanwan River. The Sanwan meets the Tildah and Banganga to join the Gambhir, also known as the Utang river. Gambhir then meets the Yamuna near Prayaraj in Allahabad.[2][3][4]
