Abstract

In this paper, the confluence hydrodynamics at the mouth of the Sava and Danube Rivers in the city of Belgrade is analysed by means of the three-dimensional numerical model. The confluence offers excellent possibilities for such investigation as the two morphological features typical for a river confluence are present: bed elevation discordance at the entrance to the confluence and the scour hole in the post-confluence channel. The results are discussed in terms of the secondary flow pattern. Since the non-defomble bed is assumed, the nature of the river bed - flow interaction is analysed in terms of a non-dimensional bed shear stress and a re-suspension number distributions for different flow conditions in the confluence.
