Question

In which type of river there is a reduction of the available slope?

(a) Braided

(b) Stable Type

(c) Aggrading Type

(d) Degrading Type

The question was posed to me during a job interview.

My question is taken from Classification of Rivers in section Rivers Behaviour, Control and Training of Irrigation Engineering

Answer 1

Correct choice is (d) Degrading Type

The best I can explain: This type of river is formed due to the constant erosion to reduce and finally dissipate available excess land scape. It is found below a dam or weir or barrage or above a cut off.
