ABSTRACT
Observations of the circulation in a hole near a constriction in Burrard Inlet are simulated using a two-dimensional (i.e., laterally integrated) numerical model. The model uses a level-2 version of the Mellor-Yamada turbulence closure scheme. During spring tides, when mixing is at its most intense, the density in the hole decreases (increases) during the large (small) floods, and there is an up-inlet current pulse into the hole during each flood regardless of the flood's strength. During the large floods in particular, the simulation is significantly improved if the explicit influence of horizontal spatial variations on the production of turbulent kinetic energy is taken into ...
