The estuarine circulation in the waters (Strait of Georgia and Juan de Fuca Strait) between Vancouver Island and the mainland is superimposed on the interactions of strong tides of the mixed type with highly complex topography which result in the formation of eddies and associated residual circulation. The major source of fresh water (Fraser River) forms a tidally and seasonally modulated (1000-10000 m³/s) buoyant jet which interacts with the strongly divergent lateral tidal streams in the Strait of Georgia. Vertical mixing by the strong tidal streams in the constricted channels leading seaward from the Strait of Georgia strongly influences the nature of the estuarine circulation. The system is subject to a further major annual modulation as deep mixed water in the system is displaced by intruding ocean water from the adjacent continental shelf. Basic features of these processes have been systematically investigated with an evolving sequence of one-, two-, and three-dimensional models. The results are shown to be consistent with field data, either existing or acquired for the purpose.
