The river system of Nepal is dived into three categories in accordance with their origins. The first category is based on three main rivers, Koshi, Gandaki and Karnali which are originated from glaciers and snow-fed lakes. Koshi River System is composition of the Tamor, Arun, Dudhkoshi, Likhu, Tamakoshi, Sunkoshi and Indravati rivers. Among them Arun and Sunkoshi is originated in Tibet. The "Saptakoshi" swollen with the waters of the seven rivers finally merges into the Ganges. Similarly the Gandaki River System from the central part of Nepal is composed with Kaligandaki, Budhigandaki, Marshyangdi, Madi Trishuli, Daraundi and Seti,rivers. When all the rivers in this system join at Devghat and then it is called the Narayani that goes on to meet the Ganges. The Karnali River System in western Nepal consists of the Humla Karnali, Mugu Karnali, Seti and Bheri rivers and is the longest river system in the country. The Humla Karnali, which rises in Tibet, is the main tributary. After entering India, this river assumes the name Gogra. The second category is based on the rivers originated in the Mahabharat range and it contains rivers like the Mechi, Mahakali, Bagmati, Kamala, Rapti, etc. The Bagmati, which rises at Bagdwar and drains out through the Chobhar gorge, is the principal river of the Katmandu Valley. Streams and rivulets originating mostly from the Chure hills make up the third category; these rivers rely on monsoon rains and are otherwise dry.
