Abstract: This paper presents the formulation of a 3-D finite element hydrodynamic model to simulate secondary flows and their damping in channel bends and flow around obstacles. An emphasis has been focused on the formulation of viscous terms that are responsible for the secondary flow development. Basic equations and associated hypothesis are also presented in this paper. Validation of the model was performed based on a complex case. The model has correctly reproduced the development and the damping of secondary currents generated by river meanders. The comparison between experimental and numerical results confirms the validity of the formulation and the reliability of the approach.
