Webchannel width and the meander belt width is expressed by the formula B=3.7W 1.12 (where B is the belt width and W is the channel width in feet for channels ranging from 5 to 13,000 ft wide). This formula results in a meander width ratio approximately equal to six (i.e., the belt width is equal to about 6 bankfull channel widths). Corridors for Webpaleochannels and paleocourses of the Mississippi River known as the Lafayette meander belt. The surface of this meander belt is covered by 2 to 5 m of Peoria Loess. The base of the Avoyelles alloformation is assumed to be a fluvial composite scour surface created by the lateral migration of the Pleistocene Mississippi River.
