Abstract: A numerical procedure for simulating the temporal variation of sediment‐transport rate and corresponding variation of bed‐material composition in a straight alluvial channel has been developed. The procedure is based on a ...

Abstract: A high-speed photographic technique was developed in this study to measure saltating trajectories and corresponding velocities and spinning rates. Particles of varied sizes, shapes, and specific gravities were used in the ...

Abstract: Knowledge of particle saltating motions near the channel bed is crucial to development of bed‐load transport theories. A real‐time flow visualization technique is applied to study these motions. This technique measures the ...

Abstract: A backward‐facing step sometimes forms in an alluvial river. The step deforms and migrates when the inflow sediment and flow conditions change. A series of experiments were conducted to investigate the migration behavior ...

Abstract: A series of experiments were conducted in a flume to study the hydraulic characteristics of the turbidity current in a reservoir. Kaolin was used as the suspended material. The plunge points were found to be unstable ...
