The fluvial system consists of drainage basin slopes and its river system with flat valley bottoms schumm 1977. Based upon investigations of ephemeral, sandbed streams in semiarid areas, schumm 1977 proposed a model of the fluvial system in which long periods of relative stability are separated by brief episodes of major morphologic change termed dynamic metastable equilibrium. Natural rivers have long been characterized by a set of fluvial patterns including straight, braided, wandering, and meandering channels and by attempts to relate those patterns to some element of flow and sediment transport lane, 1955, leopold and wolman, 1957, schumm, 1963, schumm, 1977, kellerhals et al.
