Meander is a tortuous curvy passage of stream channel progresses through base level relative change by eustatic,isostatic or tectonic kinds of upliftment acquiring the distinctive shape due to erosion at the outside concave bend as well as deposition over the inside convex streambank bend owing to fastest flow speed at outside cutbank and slowest flow speed across inside forming point bar in a presumed antecedent drainage topography during middle mature stages.The etymological name derived from the Buyuk Menderes river of Asia Minor,often represented by stream sinuosity index signifying deviation from the stream actual path with respect to expected theoretical straight passage being denoted by ratio between channel length to that of stream basin length having 1.5 beyond irregular value, tortuous as 2.1 further value designated as meandering. Incised meander is a vertical erosional incision downward in a stream channel during the rejuvenation following a uplift encompassing renewed deep erosion.Entrenched are symmetrical valley sides forming through rapid downcutting.Ingrown meanders being unsymmetrical valley forming by mild incisional lateral channel gappings having steep undercut across concave outside and a gentle slip off slope over the convex inside.
