Flow and sediment matrix for the formation of midland point bars in sand bed channel / Duratul Ain Tholibon

A large number of studies, both theoretical and experimental have been devoted to understanding the physical mechanisms underlying the bar formation. Numerous data on bar formation have been accumulated yet the methods to predict bar geometry, especially bar height are still insufficient. This resea...
