Meanders

Meanders are winding, looping curves in a river's course. They are formed as a result of erosion and deposition in the river channel. Meanders typically occur in the middle and lower courses of a river, where the water flow is slower and the sediment load is higher.

Formation of Meanders

Meanders are formed through a combination of erosion and deposition. The outer bank of a river bend experiences erosion due to the faster water flow, while the inner bank experiences deposition as the water flow slows down. This process causes the river to gradually change its course, creating the characteristic meandering pattern.

Characteristics of Meanders

Meanders can exhibit several characteristics, including point bars, cut banks, and oxbow lakes. Point bars are formed through deposition on the inner bank of a meander, while cut banks are created through erosion on the outer bank. Oxbow lakes are formed when a meander becomes so pronounced that it cuts off a section of the river, creating a U-shaped body of water.
