Abstract: The configuration of open‐channel junctions controls local sedimentary processes, channel scour, and sidewall erosion through its influence on the flow patterns established as confluent streams compete for limited channel ...

Abstract: Although a discordance in bed elevation between mainstream and tributary channels is a common feature of most river confluences, this height differential is largely ignored in many models of junction flow dynamics. Here ...

Abstract: Two series of laboratory experiments were conducted to evaluate the influence of mean flow direction and sampler size (7,6 cm aperture vs 3 cm aperture) upon the efficiency of Helley‐Smith samplers in subcritical flows. ...

Abstract: A comparison of three-dimensional flow velocity measurements, made with an acoustic Doppler profiler (aDp) from fixed and moving vessels at cross sections of the Paraná River, Argentina, was performed. The purpose was to ...

Abstract: Longitudinal stripes are a common bed form in heterogeneous alluvial sediments and consist of periodic, spanwise variations in bed texture and elevation that are aligned parallel to the mean flow direction. This paper ...

Abstract: A novel flow facility developed to enable a broad spectrum of fluid mechanics experiments involving complex geometries and employing high-fidelity optical diagnostics is described in this paper. The development of the ...

Abstract: This technical note describes use of a multibeam echosounder (MBES) to quantify the dynamics of suspended sediment in a large open channel. A methodology is detailed that uses the backscatter magnitude from the MBES ...
