Question

In which parts of India do non perennial rivers flow?

(a) North India

(b) Central and South India

(c) Eastern India

(d) West India

This question was addressed to me during an interview for a job.

The origin of the question is Indian Rivers and Their Classification in chapter Rivers Behaviour, Control and Training of Irrigation Engineering

Answer 1

Correct choice is (b) Central and South India

For explanation: These rivers flow in Central and Southern India, as these regions are full of plateaus, valleys which is not the case in Northern India where the land terrain is of plains. Here the rivers do not have a constant water source as in case of perennial rivers, which have Himalayan mountain ranges ice as their source.
