Combined tidal and wind driven flows and residual currents

Currents in Stratified Water Bodies 1: Density-Driven Flows

A Numerical Modeling Framework for Cohesive Sediment Transport Driven by Waves and Tidal Currents

1. Developing a 3D turbulence-resolving numerical model for fine sediment transport in the oscillatory boundary layer in order to understand how turbulencesediment interactions can determine the state of muddy seabed (transport modes). 2. Studying the attenuation of turbulence due to the presence of sediment via the interplay between sediment-induced density stratification and enhanced viscosit...

The predictability of large-scale wind-driven flows

The singular values associated with optimally growing perturbations to stationary and time-dependent solutions for the general circulation in an ocean basin provide a measure of the rate at which solutions with nearby initial conditions begin to diverge, and hence, a measure of the predictability of the flow. In this paper, the singular vectors and singular values of stationary and evolving exa...

Across-channel distribution of the mean and tidal flows in the Khuran Channel, Persian Gulf, Iran

The Khuran Channel, Southern Iran (26°45’N), is a topographically complex channel which is open at both ends. Owning to its particular geometry, this narrow channel is subjected to strong tidal currents.Across-channel distribution of the mean and tidal flows were obtained over a semidiurnal tidal cycle in the Khuran Channel where the highest tidal velocity in the third day of the seco...

Residual Exchange Flows in Subtropical Estuaries

Observations of residual exchange flows at the entrance to four subtropical estuaries, two of them semiarid, indicate that these flows are mainly tidally driven, as they compare favorably with theoretical patterns of tidal residual flows. In every estuary examined, the tidal behavior was that of a standing or near-standing wave, i.e., tidal elevation and tidal currents were nearly in quadrature...
