The Indus hit the news big-time in 2010 when flooding triggered the worst humanitarian crisis in Pakistan's history, killing many and displacing millions.
The Indus is known as Senggye Tsangpo (Tibetan), and Shiquan He (Chinese). Originating in the Tibetan plateau in the vicinity of Lake Mansarovar in Tibet, the Indus runs through the Ladakh district of Jammu and Kashmir and then enters Pakistan's Northern Areas, flowing south along the entire length of Pakistan to merge into the Arabian Sea near the port city of Karachi. The Indus covers a distance of around 3,180 kilometres, and is Pakistan's longest river.
Sourced from the same region in Tibet—the Mount Kailash region—the Sutlej River (Langchan Khambab) carves a quite different path, but meets up with the Indus in the mid-section of Pakistan, joining forces for the final rush to the sea.
