Abstract

Spatial complexity of turbulent flow conditions has been investigated by means of ADCP measurements and CFD modelling in river Danube. The study area was a meandering river reach, characterized by shallows and strongly influenced by various river training works. High resolution bed survey and freezing plate sampling provided input river bed data for model implementation. The applied k-ε turbulence model could well reproduce velocity distributions measured in nature. Strong spatial variability of the velocity and turbulent kinetic energy fields demonstrated the necessity of 3D model approach under such fluvial conditions.
