A meander has an asymmetrical cross section due to the differential erosion and deposition of sediments along its curves. The outer bank of the meander experiences faster water flow, leading to increased erosion and a steeper slope. In contrast, the inner bank has slower water flow, promoting sediment deposition and creating a gentler slope. This dynamic results in the characteristic asymmetrical shape of meander cross sections.
