Brian P. Neff, Sheridan K. Haack, Donald O. Rosenberry, Jacqueline F. Savino, Scott C. Lundstrom
2006, Book chapter, Coastal hydrology and processes
Key similarities exist between marine and Great Lakes coastal environments. Water and nutrient fluxes across lakebeds in the Great Lakes are influenced by seiche and wind set-up and set-down, analogous to tidal influence in marine settings. Groundwater/surface-water interactions also commonly involve a saline-fresh water interface, although in the Great-Lakes cases,...

2006, San Francisco Estuary and Watershed Science (4) 91-102
Residence times of dissolved substances and sedimentation rates in tidal channels are affected by residual (tidally averaged) circulation patterns. One influence on these circulation patterns is the longitudinal density gradient. In most estuaries the longitudinal density gradient typically maintains a constant direction. However, a junction of tidal channels can create...
