THE EXCHANGE OF HATER IN FJORDS: A SIMPLE MODEL OF TWO-LAYER ADVECTIVE REACHES SEPARATED BY MIXING ZONES

E.D. Cokelet, R.J. Stewart, C.C. Ebbesmeyer

Abstract


He propose a model for the two-layer, mean transport within a branched, recirculating fjord system. The recirculation is parameterized in terms of efflux/reflux coefficients at distinct mixing zones. The mass fluxes and efflux/reflux coefficients are determined from long-term salinity and current meter observations. The model provides a way to predict the mean concentrations of pollutants introduced within the system. An application to Puget Sound shows that different discharge sites markedly affect the concentrations landward of the sites themselves.
