The Arun River (Nepali: अरुण नदी) is a largest trans Himalayan and trans-boundary
river (Nepal, China) and is part of the Kosi or Saptakoshi river of Nepal. The Arun is the largest river passing
through Nepal and also has the greatest snow and ice-covered area of any
Nepalese river basin. The River runs 510 Km from its origin before merging in
Saptakoshi river after collecting water from 36,000 Sq. Km catchment area with
North to south alignments. The altitude variation of river is 150 meter to
8,470 meter. The Arun drains more than half of the area contributing to the
Saptakoshi river system but provides only about a quarter of the total
discharge. The river has enormous hydroelectricity power with clean and high
dense water with estimated hydroelectricity capacity of 1185 megawatt at six
sites, where 900 megawatts Arun III Hydroelectricity project is under construction.
