Hydraulics of Stratified Two-layer Flow in Rječina Estuary
The salinity distributions in the Rječina Estuary, in Croatia, are thoroughly studied through intensive sampling campaigns. Strong vertical stratification was observed throughout the tidal cycle, proving the limited vertical mixing between seawater and freshwater layer, and implying the presence of salt wedge. The salt wedge is developed at the downstream river part, and its length is found to be directly related to Rječina River discharges. The length of the wedge is also dependent, but in smaller intense, to tidal phases. Bathymetry also plays a major role in wedge propagation, especially during small river discharges. A one- dimensional model for two-layer stratified flow, based on Schijf and Schonfeld model, was developed and used. By calibrating the interfacial friction factor, calculated density interface fitted very well to measured data.
