The Rigveda refers to a number of rivers located in the northwestern Indian subcontinent, from Gandhara to Kurukshetra.
Identification of Rigvedic hydronyms has engaged multiple historians; it is the single most important way of establishing the geography and chronology of the early Vedic period.
[1][2] Rivers with certain identifications stretch from eastern Afghanistan to the western Gangetic plain, clustering in the Punjab.
[a] The region's name comes from پنج, panj, 'five' and آب, āb, 'water' thus "five waters", a Persian calque of the Indo-Aryan Pancha-nada meaning "five rivers".
[4] The same names were often imposed on different rivers as the Vedic culture migrated eastward from around Afghanistan (where they stayed for a considerable time) to the subcontinent via Punjab.
