Abstract: Characteristics of a buoyant surface jet discharged on a sloping bottom are reviewed and a numerical experiment is performed to evaluate the depth at the point where the jet detaches from the bottom. This calculation is ...

Abstract: It is shown that conditions underneath freezing or melting sea ice may be established which are favorable for double-diffusive convection. Salt fingers are possible when the ice cover is growing, while the overstable mode ...

Abstract: Much work is done to understand the mixing processes at a density interface. Laboratory studies commonly rely on experiments where entrainment is driven by either a mean shear or by a vertically oscillating grid. Although ...

Abstract: A model is proposed for the surface erosion of cohesive soils on the basis of the physical interaction of turbulent bursts with the sediment bed. More specifically, the model deals with floc-by-floc erosion, appropriate ...

Abstract: Experiments were performed to evaluate changes in suspended particle-size distribution as a function of variations in mixing conditions. Suspensions were taken from Lake Erie near Buffalo, N.Y., and mixed in a standard jar ...

Abstract: Particle image velocimetry (PIV) is used to measure two-dimensional velocity fields in a standard jar test tank for different impeller speeds. General flow patterns are obtained for the whole tank, and small scale (∼1 cm

Abstract: Fish passage design could greatly benefit from knowledge of the movement and path choices of fish in complex, turbulent environments, but empirical information required to construct and validate agent-based models is ...

Abstract: When we consider a location with a material (e.g., water, pollutant, sediment) passing through it, we can ask: “Where did the material come from and how long did it take to reach the location?” We can quantify the answer ...

Abstract: Procedures have been developed to allow linkages between finite-difference hydrodynamic and water quality models having different temporal and spatial scales by defining appropriate values for the mean flow and dispersion ...
