1. Colbo, Keir Murray. Mixing processes near boundaries.

Degree: School of Earth and Ocean Sciences, 2018, University of Victoria

Using a large eddy simulation (LES) model the cross-cell diffusion of neutrally buoyant and buoyant particles in Langmuir circulation is studied. The non-dimensional diffusivity is found to asymptote to a constant value for sufficiently small Langmuir number. This allows a parameterization for the cross-cell diffusivity that depends only on well known physical properties of the wind and wave field. Buoyant particles are found to behave similarly, but with a substantial reduction of the cross-cell diffusivity. Lateral Reynolds stresses from an array of acoustic Doppler current profilers (ADCPs) are computed for fluctuations about a tidal mean. The results are compared with the observed lateral shear to estimate the horizontal eddy viscosity, O (10 m2/s). Possible parameterizations of the eddy viscosity are discussed. The lateral Reynolds stresses acting on the estuarine mean flow are also calculated. The velocity data from the ADCPs along with density data from temperature chain moorings are used to examine the partition of energy between internal waves and the vortical mode. Consistency relations for the ratio of counterclockwise to clockwise energy (CCW/CW) and potential to horizontal kinetic energy (PE/HKE) are modified to account for the effect of boundaries and Doppler shifting. Exact partitioning of the energy is not possible, but the signature of both internal waves and vortical modes can be detected. Advisors/Committee Members: Garrett, Christopher J. R. (supervisor).
