Abstract: Several formulas are theoretically and empirically proposed for the alternate bar wavelength. These formulas are tested with laboratory data presented herein and those reported by other workers. It is found that one formula ...

Abstract: Mathematical models for defining three‐dimensional flow and bed topography in sinuous channels with suspendable bed material are presented. It is shown theoretically that the secondary flow in sinuous channels shows a ...

Abstract: Experiments on the suspension of sediment were performed in flume with and without sediment layer on the bottom. For movable bed runs three‐dimensional sand ripples were found to affect seriously the features of suspended ...

Abstract: A mathematical model for defining the lateral bed topography in bends of sand‐silt rivers is presented. The model includes the effects of suspended sediment that have not been considered in the existing models. The major ...

Abstract: Open channel flow over flexible bottom vegetation is studied experimentally. Two-component laser-Doppler velocimetry is used to measure the longitudinal and vertical velocity components of the flow field. It is observed ...

Abstract: A mathematical model for defining the bed topography and the bed material size distribution in uniformly curved bends of alluvial rivers is developed, in which the coarsening of sediment size toward the outside bank is ...

Abstract: A mathematical model for defining lateral distributions of fluid velocity and suspended sediment concentration in straight channels with pile dikes near the banks is presented. Singular perturbation and matched asymptotic ...
