Kali Gandaki -Trishuli

Kali Gandaki is joined by a major tributary, Trishuli, at Devighat, just as the river exits the foothills of the Himalayas into the southern plains of Nepal. Masryangdi is a major tibutary of Trisuli. From Devighat, the river flows southwest and is known as Narayani or Sapt Gandaki. The river later curves back towards the southeast as it enters India. http://en.wikipedia.org/wiki/Gandaki_River
