Abstract

Depth-averaged numerical modeling 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 unvafourable 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. -Authors
