Abstract: Presented here are detailed descriptions of ice-jam processes at river-channel confluences. The descriptions are based on observations obtained from a small-scale hydraulic model of variable geometry and on field observations ...

Abstract: Velocity measurements, using a two‐dimensional laser Doppler velocimeter (LDV), were made in turbulent channel flows of water, at a Reynolds number of 60,000, over a flat stationary sediment bed with covers of different ...

Abstract: Experiments were performed to measure the mean velocity and turbulence characteristics in open-channel flows with and without suspended sediment (alluvial sand of nearly uniform size). Velocity measurements were obtained ...

Abstract: Large scale particle image velocimetry (LSPIV) is an extension of quantitative imaging techniques for measurements of water surface velocities using inexpensive standard video equipment. The present Technical Note describes ...

Abstract: A method is proposed for estimating rates of sediment transport in ice-covered alluvial channels. The method extends existing, open-water procedures for estimating rates of sediment transport to conditions of ice-covered ...

Abstract: New field data on cohesive sediment erosion is presented and discussed, with particular focus on partitioning the total erosion into resuspension and bed load. The data were obtained using a recently developed in situ flume ...
