How big is indus plain which cities does it cover?
Answers
The Indus River plain is a vast expanse of fertile land, covering about 200,000 square miles (518,000 square km), with a gentle slope from the Himalayan piedmont in the north to the Arabian Sea in the south. The average gradient of the slope is no more than 1 foot per mile (1 metre per 5 km). Except for the micro relief, the plain is featureless. It is divisible into two sections, the upper and lower Indus plains, on account of their differing physiographic features. The upper Indus plain is drained by the Indus together with its tributaries, the Jhelum, Chenab, Ravi, Beas, and Sutlej rivers, forming a developed system of interfluves, known locally as doabs, in Punjab province (Persian panj āb, “five waters,” in reference to the five rivers). In the lower plain the Indus River has a Nilotic character; i.e., it forms a single large river with no significant tributaries. The plain narrows to form a corridor near Mithankot, where the Sulaiman Range comes close to the plain and the Indus merges with its last major tributary, the Panjnad River (which is itself merely the confluence of the five Punjab rivers). Flooding is a perennial problem, especially along the Indus, as a consequence of heavy rains (usually in July and August).
