A feature commonly found in the youthful stage of a river is a meander. A meander is a bend or curve in a river that forms as the river erodes the outer bank and deposit sediment on the inner bank. Meanders are characteristic of a youthful river because the river has a lot of energy and is actively eroding and depositing sediment. As the river ages and slows down, the meanders become more pronounced and can eventually lead to the formation of ox-bow lakes. Ox-bow lakes are formed when a meander becomes so pronounced that the river cuts through the narrow strip of land, creating a new channel. The old channel becomes isolated and forms a lake. Levees are mounds of sediment that form along the banks of a river and are used to prevent flooding. Interlocking spurs are ridges of rock or sediment that form along a river and help to control the river's flow.
