Meandering point bar
http://www.physicalgeography.net/fundamentals/10z.html WebJan 1, 2014 · Point bar (synonyms: meander bar): a channel bar of mud to conglomerate forming on the convex side (or inner bank) of a channel bend (inner bend) due to reduced flow velocity or flow separation (Kearey 1996 ). Point bars are diachronous, time-transgressive, laterally continuous, fining upward sequences (Fig. 2 ).

WebA bar in a river is an elevated region of sediment (such as sand or gravel) that has been deposited by the flow. Types of bars include mid-channel bars (also called braid bars and common in braided rivers ), point bars (common in meandering rivers ), and mouth bars (common in river deltas ). WebTopographically, the point bar environment may be subdivided into four arcuate-shaped depositional areas of different, but relative elevations related to river stages and also of different, but relative, positions within the meander loop related to distances from the undercut bank.
