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: Large-eddy simulation (LES) and laboratory-flume visualizations were used to investigate coherent structures present in the flow field around a circular cylinder located in a scour hole. The bathymetry corresponds to ...

Abstract: This paper uses results from detached eddy simulation to reveal the dynamics of large-scale coherent eddies in the flow around a circular pier with an equilibrium scour hole. This is important for the sediment transport ...

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: A study is reported of the wind-driven breakoff of rivulets and subsequent droplet flows on a horizontal plate subject to different normal gravitational states, ranging from zero- to terrestrial-gravity ...

Abstract: Cable‐moored platforms may be an attractive engineering approach to the problem of conducting engineering activities such as drilling in moderately deep (20–70 m) ice‐covered waters. However, the dynamic performance of ...

Abstract: Brash ice commonly covers ice-covered navigation channels in rivers, waterways, and harbors. Barges, therefore, frequently encounter it. This paper presents ice-tank observations and data indicating the levels of resistance ...

Abstract: This paper is intended to be the first of a series of papers presenting the results of a comprehensive study aimed at evaluating the influences of two large hydropower generation stations on ice transport and jamming in ...
