Meander

Section between two successive turning points. On the outside of the curve (or extrados) the concave river bank is eroded, steep, and conducive to lateral erosion. On the inside of the curve (or intrados) the convex river bank is sloping gently, suitable for sedimentation of alluvial benches. There are two main types of meanders, incised meanders and free meanders, and an intermediate type, forced cut meanders.
