Which river originating from the Himalayas flows

The Yamuna River originates from the Yamunotri Glacier in the Himalayas (Uttarakhand).
Course:
It flows parallel to the Ganga for much of its course through northern India.
Eventually, it joins the Ganga at Prayagraj (Allahabad), forming the famous Triveni Sangam (confluence of Ganga, Yamuna, and the mythical Saraswati).
Right-bank Tributary:
A right-bank tributary means the river joins the main river from the right side (when looking downstream).
The Yamuna flows to the west of the Ganga and merges from the right, making it the largest right-bank tributary of the Ganga.
Significance:
The Yamuna is considered sacred in Hindu tradition, just like the Ganga.
It supports major cities along its course, including Delhi, Mathura, and Agra.
It plays a crucial role in irrigation, drinking water supply, and cultural heritage.
In short: The Yamuna River, originating from the Himalayas, flows parallel to the Ganga and joins it as a right-bank tributary at Prayagraj.
