AB: Residual circulation in estuaries usually display a characteristic estuarine circulation pattern with inflowing deep waters and outflowing surface waters. The strength being dependend on the tidal prism and the fresh water inflow to the estuary. In estuaries with a strong circulation this leads to formation of distinct water masses. However, in estuaries where vertical mixing is significant, at least part of the time, the importance of the residual circulation for transport of dissolved substances may be seriously reduced. The talk will draw upon recent work using the MIKE 3 unstructured mesh circulation models, set up as part of the USGS Tampa Integrated Science Project. The significance of the residual transport, the quantification of it in a typical Gulf Coast estuary and the relevance for estuarine management strategies will be discussed.
