Abstract: A new, concise theoretical model for simulation of unsteady, nonhydrostatic two-layer flow is presented. The formulation is systematically developed from the equations of motion of an ideal fluid using a perturbation ...

Abstract: The results of a flume experiment and a theoretical study of surface wave motion over a fluidized bed are presented. It is shown that a resonant wave interaction between a surface wave and ...

Abstract: Most analyses of turbulent mixing in rivers assume constant hydraulic geometry (width, depth, and velocity), despite the fact that in natural rivers these variables typically increase downstream. A comprehensive set of ...
