River Beas, flowing from Himachal and Punjab, joins the river

The Beas River originates from Beas Kund near the Rohtang Pass in Himachal Pradesh [4]. It flows through the Kullu valley and enters the Punjab plains near Mirthal [6]. The river's journey concludes at Harike in the Kapurthala district of Punjab, where it joins the Satluj River [3]. This confluence at Harike is a significant geographical point where the Harike Barrage is located, diverting water into major irrigation canals [1]. Historically, the Beas changed its course about 250 years ago to join the Satluj near Sultanpur [5]. While the Beas is a part of the larger Indus River system, it specifically merges with the Satluj within Indian territory before the combined waters eventually enter Pakistan to join the other rivers of the Panjnad [2].
