Ravi (rivière)
Résumé
The Ravi River (ˈrɑːvi) is a transboundary river crossing northwestern India and eastern Pakistan. It is one of five rivers associated with the Punjab region.
Under the Indus Waters Treaty of 1960, the waters of the Ravi and two other rivers (Sutlej and Beas River) were allocated to India. Subsequently, the Indus Basin Project was developed in Pakistan, which transfers waters from western rivers of the Indus system to replenish the portion of the Ravi River lying in that country. Many inter-basin water transfers, irrigation, hydropower and multipurpose projects have been built in India.
According to ancient history traced to Vedas, the Ravi River was known as Irāvatī (इरावती).
The Ravi was known as Purushni or Irawati to Indians in Vedic times and as Hydraotes (’Υδραωτης) to the Ancient Greeks.
Part of the Battle of the Ten Kings was fought on a river, which according to Yaska (Nirukta 9.26) refers to the Iravati River (Raavi River) in the Punjab.
The Ravi River, a transboundary river of India and Pakistan, is an integral part of the Indus River Basin and forms the headwaters of the Indus basin. The waters of the Ravi River drain into the Arabian Sea (Indian Ocean) through the Indus River in Pakistan. The river rises in the Bara Bhangal, Kangra District in Himachal Pradesh, India. The river drains a total catchment area of in India after flowing for a length of . Flowing westward, it is hemmed by the Pir Panjal and Dhauladhar ranges, forming a triangular zone.
