Question

Explain the process of formation of meanders in the middle course of the river.

Answer 1

Meanders form in the river’s middle course where the gradient is gentle, reducing velocity. The river erodes the outer curve (concave side) due to higher speed, creating a cut bank, while depositing sediments on the inner curve (convex side) where velocity is lower, forming a slip-off bank. This erosion and deposition enlarge the bends, creating meanders.
