Explanation

The bends formed in a river, where the water erodes its banks on the outside of the channel, are known as meanders. Explanation: Meanders are curves or bends in a river that form as the water flows in a winding path. The outside of a meander (called the cut bank) experiences erosion due to the faster flow of water. The inside of a meander (called the point bar) experiences deposition as the water flow is slower. Meanders are a common feature in the middle and lower courses of rivers where the gradient is gentler, allowing the river to flow more sinuously.
