Longitudinal roughness
WebSimilar to the flow resistance, also the longitudinal dispersion, i.e., the diffusive properties of the velocity distribution, is affected by riverbed roughness. Longitudinal dispersion was analyzed by Taylor [1953, 1954] and can be described as a balance of two counteracting processes: the extension of longitudinal concentration gradients by ...
