Variability of River Patterns

Article metrics


MODEL studies1 of the dependence of river patterns on sediment load and on the inclination of the surface on which the model river flows—the valley slope—show that at a constant discharge very different channel patterns are formed at different slopes (Fig. 1). Although sediment load is also an important factor affecting the sinuosity of a model river, Fig. 1 shows that an abrupt change in valley slope should lead to a change in river pattern.
