(c) 5

(d) 4

This question was posed to me in an international level competition.

My question comes from Behavior of Rivers topic in portion Rivers Behaviour, Control and Training of Irrigation Engineering

Answer 1

Right choice is (d) 4

To explain: Four variables govern the meandering process, namely silt grade and silt charge, discharge, bed and side materials and their action towards erosion, and valley slope. These all variables affect the meandering process, and all of them are interdependent.
