Abstract:
Within estuaries, there is a mix of salty and freshwater regulated by hydrodynamic drivers such as tide, wind, density gradients, and waves. These forcings interact with bathymetry and between each other to induce a residual (non-tidal) circulation. This study investigates the interaction of estuarine drivers at two locations, using observations and idealized numerical experiments. Two chapters deal with the residual circulation and the exchange processes in two morphologically different estuaries. The second chapter explores a coastal plain estuary where wind forcing induced a residual circulation that agreed with theoretical results. This wind-driven circulation altered density gradients and masked the gravitational, or density-driven, circulation. The third chapter concentrates in a multiple-inlet estuary where a freshwater coastal current from the inner shelf allowed the development of a salt-plug inside the estuary. The salt-plug promoted an inverse residual circulation in the main inlet with inflow at the surface and outflow underneath. Lastly, the fourth chapter uses an idealized numerical model to explain the mechanism that triggers the formation of the salt-plug. The main contributions of this research are twofold. The investigation provides observational evidence of the wind-driven flow lateral structure in estuaries. It also explains a new mechanism for salt-plug formation inside a system. These processes influence the water quality of estuaries by affecting their flushing and residence times. ( en )
