Question : 25 [SSC CML 2001]

The greatest erosive power of a river is associated with

a) inter-locking spurs

b) gorges

c) V-shaped valley

d) meanders

Answer: (d)

The erosive power of a stream is proportional to the square of the velocity. Thus, when discharge increases, the depth increases and the velocity increases, resulting in a dramatic increase of erosive power.

As the volume flowing in a stream increases, the stream's erosive power also increases. At a bend in a stream, the water's momentum carries the mass of the water against the outer bank. The greater depth on the outer side of the bend also leads to a higher velocity at the outer bank.

The greater velocity combined with the greater inertial force on the outer bank erodes a deeper channel. The result of all these actions is a meander
