Stream order is an important aspect of a drainage basin. It is defined as the measure of the position of a stream in the hierarchy of streams. Tributaries are given a number one greater than that of the river or stream into which they discharge. So, for example, all immediate tributaries of the main stem are given the number "2".
A confluence can occur in several configurations: at the point where a tributary joins a larger river ; or where two streams meet to become the source of a river of a new name (such as the confluence of the Monongahela and Allegheny rivers at Pittsburgh, forming the Ohio); or where two separated channels of a river (forming a river island ...
Yazoo stream.

This is especially the characteristic when such a stream is forced to flow along ...
A diagram of a possible river with the Strahler number of each tributary labeled. In hydrology, a stream order is a positive integer used to describe the level of river branching in a drainage basin. [20] Several systems of stream order exist, one of which is the Strahler number. In this system, the first tributaries of a river are 1st order ...
Its left-bank tributary in Ladakh is the Zanskar River, and its left-bank tributary in the plains is the Panjnad River which is formed by the successive confluences of the five Punjab rivers, namely the Chenab, Jhelum, Ravi, Beas, and Sutlej rivers.
