Ans. The following events lead to the formation of meanders:In a meandering channel, both erosion and deposition take place simultaneously. The erosion occurs in the concave bank, which is also known as the cut bank, and deposition took place in the convex bank where pointed bars are formed. When the bends of a meander get deeper, it leaves that bend and flows in the straight path. That abounded bend later became known as the ox-bow lake.The secondary flow is more dominant than the irrotational flow. Irrotational flow is almost absent in a meandering course of the river.
