The place located, at the confluence of Alaknanda and Bhagirathi rivers

The confluence of the Alaknanda and Bhagirathi rivers occurs at Devprayag in the Tehri Garhwal district of Uttarakhand [2]. This location is of immense geographical and cultural significance as it marks the official formation of the River Ganga; prior to this point, the headwaters are known as the Bhagirathi, which originates from the Gaumukh at the Gangotri Glacier [4]. Devprayag is the final of the 'Panch Prayag' (five sacred confluences) along the Alaknanda river system [1]. Other confluences include Rudraprayag, where the Alaknanda meets the Mandakini, and Vishnuprayag, where it meets the Dhauliganga [3]. While Badrinath is situated along the banks of the Alaknanda near its source at the Satopanth Glacier, and Rishikesh is a holy city further downstream where the Ganga enters the plains, only Devprayag serves as the specific meeting point for the Alaknanda and Bhagirathi [2].
