Abstract
Depth-averaged numerical modelling of steady-state horizontal flow patterns carried out in
the framework of the revitalisation project of the secondary branches in Gemenc Protected
Landscape Area is presented. The feasibility of different variants is investigated in order
to increase the water exchange in the secondary branches without creating unfavorable
hydraulic and related sediment transport as well as navigation conditions. The applied
mathematical model is based on the usual shallow water assumptions. The numerical
solution is performed using finite differences and multigrid iteration technique. The model
is able to reproduce recirculation zones and the horizontal velocity distribution in an
acceptable manner
