It is produced as a watercourse erodes the sediments of an outer, concave bank (cut bank) and deposits sediments on an inner, convex bank which is typically a point bar. This results in the formation of a slip-off-slope on the inside bend of the river.Over time, rivers change shape due to both erosion and deposition, causing the river to change shape and slowly migrate downstream. At that point in time, the Mississippi flowed down this course. As a river reaches flatter land, it swings from side to side, forming winding bends called meanders. Just after the cutoff meander is formed, the river flows into its end from the river and builds a small delta which eventually results in the formation of oxbow lakes.
