Meanders are sinuous bends in a river with a faster flow of water on the outside channel leaving the inside to be slower therefore depositing sediments. The water flows faster on the outside bend of a river because it has further to travel, its speed and erosive power is therefore greater. This erodes the outside of the meander, producing a river cliff and deeper channel on that side. The bends become deeper and deeper in time, until the water finds a shortcut and the bends are cut off, drying out or becomes separate lakes.
