The Tamur River (Nepali: तमोर नदी) is a major river in eastern Nepal, which begins around Kanchenjunga. The Tamur and the Arun join the Sun Kosi at Tribenighat to form the giant Saptakoshi which flows through Mahabharat Range on to the Gangetic plain

Kosi river system

The Kosi or Sapt Kosi drains eastern Nepal. It is known as Sapt Koshi because of the seven rivers which join together in east-central Nepal to form this river. The main rivers forming the Kosi system are – the Sun Kosi River, the Indravati River, the Bhola Koshi, the Dudh Kosi, Arun River, Barun River, and Tamur River. The combined river flows through the Chatra gorge in a southerly direction to emerge from the hills.

The Sun Kosi contributes 44 per cent of the total water in the Sapta Koshi , the Arun 37 per cent and the Tamur 19 per cent.
