A mathematical model of mud transport in deep partially mixed canalized estuaries

The report describes the theory and first application of a new type of multi-layer model which can simulate the interaction of tidal and fluvial flows on saline intrusion, mud transport and siltation in deep partially mixed canalised estuaries. The physics of the various interacting processes are described. Novel aspects include the method of calculating vertical mixing and the modelling of the formation of a thin layered slack water deposit.
