Three-dimensional flow modelling and sediment transport in the River Klarälven

Auteur :
DARGAHI, B.

Description :
A three-dimensional flow model that uses the RNG turbulence model and a non-equilibrium wall function was applied to the River Klarälven in the southwest part of Sweden. The objectives were to study the nature of the flow in the river bifurcation and to investigate the short-term sediment transport patterns in the river. The numerical models were built and verified using extensive field data. Based on model outputs, observations are made about the velocity vectors and the secondary flow patterns. The main sediment transport patterns in the river were also investigated by solving the sediment continuity equation for the total sediment load.
