Koshi River-rafting

The Kosi River
The Kosi River, called Koshi in Nepal (Nepali: कोशी नदी), is a transboundary river between Nepal and India, and is one of the largest tributaries of the Ganges. The river, along with its tributaries, drains a total area of 69,300 km2 (26,800 sq mi) up to its confluence with the Ganges in India (29,400 km2/11,400 sq mi in China, 30,700 km2/11,900 sq mi in Nepal and 9,200 km2/3,600 sq mi in India). The watershed also includes part of Tibet, such as the Mount Everest region, and the eastern third of Nepal. The river basin is surrounded by the ridges separating it from the Brahmaputra in the north, the Gandaki in the west, the Mahananda in the east, and by the Ganges in the south. The river is joined by major tributaries, approximately 48 km (30 mi) north of the Indo-Nepal border, breaking into more than twelve distinct channels with shifting courses due to flooding. Kamlā, Bāghmati (Kareh) and Budhi Gandak are major tributaries of Koshi in India, besides minor tributaries like Bhutahi Balān. Over the last 250 years, the Kosi River has shifted its course over 120 kilometres (75 mi) from east to west. and the unstable nature of the river is attributed to the heavy silt which it carries during the monsoon season. Flooding in India has extreme effects. India is second in the world after Bangladesh in deaths due to flooding, accounting for one fifth of global flooding deaths. The Kosi River (The Sorrow of Bihar) is one of two major tributaries, the other river being Gandak, draining the plains of north Bihar, the most flood-prone area of India.

Legend
Formerly Kauśiki (named after sage Viśvāmitra because Viśvāmitra is said to have attained the status of Vedic ṛṣi or Rishi on its banks; Viśvāmitra was descendant of sage Kuśika and was called Kauśika in Rgveda), in Nepal and Bihar in northern India is a major tributary of the Ganges (one major tributary of the Koshi is the Arun, a major part of whose course is in Tibet). This river is mentioned in the epic Mahabharata as Kauśiki. Seven Koshis join together to form the Saptakoshi River/Sapt Koshi which is popularly known as the Koshi.
It is also the lifeline of the Mithila region, today spread over more than half of India's state of Bihar, and parts of adjoining Nepal and it forms the basis of legend and folklore of the region; the legend of Mithila extends over many centuries. Mithila is also the name of a style of Hindu art created in the Mithila area.
