Drivers of residual estuarine circulation in tidally energetic estuaries: Straight and irrotational channels with parabolic cross section

The generation of residual circulation in a tidally energetic estuary with constant longitudinal salinity gradient and parabolic cross section is examined by means of a two-dimensional cross-sectional numerical model, neglecting river runoff and Stokes drift. It is shown how the longitudinal and lateral residual circulation can be decomposed...

A Simple Diffusion-Controled Model of Mixing Across a Stable Density Interface

Mixing across a stable density interface caused by a shear stress externally acting on a two-layer fluid initially at rest is modelled using the turbulent-diffusion concept. The influence of a (relatively weak) longitudinal pressure gradient is also considered. The central point of view developed is that the mixed layer can be only weakly...
