Correct Answer:
Option A - The classifications of river channel pattern are of three essential types: straight, meandering and braided.
Straight channels, mainly unstable, develop along the lines of faults and master joints, on steep slopes where rills closely follow the surface gradient, and in some delta outlets.
A meandering stream has a single channel that winds snakelike through its valley, so that the distance 'as the stream flows' is greater than 'as the crow flies. ' As water flows around these curves, the outer edge of water is moving faster than the inner.
Braided streams and rivers have multi-threaded channels that branch and merge to create the characteristic braided pattern. Braided channels are highly dynamic with mid-channel bars which are formed, consumed, and re-formed continuously. The development of braided channels is favored by several factors
