The Indus water system of rivers comprises the main Indus and its major tributaries: the Kabul River and Kurram River on the right bank, and the Jhelum River, Chenab River, Ravi River, Beas River and the Sutlej on the left. The first two join the Indus soon after it leaves the mountains, and the others lower down in the plains. The whole of the Beas and the head reaches of the Ravi and Sutlej are in the Republic of India, while those of the Chenab and Jhelum lie mostly in the disputed Kashmir state.
