hii guys...... indus river system please explain briefly.......urgent help

Answer 1

Over 60% of the total area of the Indus drainage basin is in Pakistan and Pakistan-administered Kashmir. India has about 22%, Tibet has 10% and Afghanistan has 7% of the Indus basin catchment area.

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.

The entire basin covers an area of about 384,000 square miles of open land, of which 204,000 lie in Pakistan. In addition, there are about 29,000 square miles which lie outside the Indus basin but are dependent on the Indus river system for their water requirements and irrigation supplies.

Without the Indus waters, agriculture in Pakistan would be very uncertain, because there isn't much rain. Even now when Pakistan is being rapidly industrialised, it needs its water resources, because a very big percentage of its existing and proposed industry has to draw upon the agriculture produce for its raw materials. Almost all of the basin in Pakistan receives an overall rainfull of less than 15 inches, 60% of its area receiving less than 10 inches, while, 16% receives less than 5 inches. The rainfull is not evenly distributed throughout the year but is concentrated during the monsoons.
The river has a total drainage area exceeding 1,165,000 km2 (450,000 sq mi). Its estimated annual flow stands at around 243 km3 (58 cu mi), twice that of the Nile River and three times that of the Tigris and Euphrates rivers combined, making it the twenty-first largest river in the world in terms of annual flow. The Zanskar is its left bank tributary in Ladakh. In the plains, its left bank tributary is the Chenab which itself has four major tributaries, namely, the Jhelum, the Ravi, the Beas, and the Sutlej. Its principal right bank tributaries are the Shyok, the Gilgit, the Kabul, the Gomal, and the Kurram. Beginning in a mountain spring and fed with glaciers and rivers in the Himalayas, the river supports ecosystems of temperate forests, plains and arid countryside.

The northern part of the Indus Valley, with its tributaries, forms the Punjabregion, while the lower course of the Indus is known as Sindh and ends in a large delta. The river has historically been important to many cultures of the region. The 3rd millennium BC saw the rise of a major urban civilization of the Bronze Age. During the 2nd millennium BC, the Punjab region was mentioned in the hymns of the Rigveda as Sapta Sindhu and the Zoroastrian Avesta as Hapta Hindu (both terms meaning "seven rivers"). Early historical kingdoms that arose in the Indus Valley include Gandhāra, and the Ror dynasty of Sauvīra. The Indus River came into the knowledge of the West early in the Classical Period, when King Darius of Persia sent his Greek subject Scylax of Caryanda to explore the river, ca. 515 BC.
