The Indravati meets the Sun Kosi at Dolaghat, up to where it is followed by the Arniko Rajmarg. From there, the Sun Kosi flows eastwards through the valley formed between the Mahabharat Range and the Himalayas. Tamakosi, Likhu, Dudhkosi, Arun and Tamor are its left tributaries and Indravati is the right tributary.
