APPLICATION OF NUMERICAL MODEL SIMULATIONS FOR ESTIMATION OF MORPHDYNAMICS AND VEGETATION IMPACT ON TRANSPORT OF DISSOLVED SUBSTANCES IN THE WARTA RIVER REACH

Keywords: river processes, admixture transport, sediment accumulation, riparian vegetation
Abstract:

The main problem analysed in this paper is the impact of sediment accumulation and vegetation growth on transport of dissolved substances in a river. The system studied is the reach of the Warta River located upstream of the Jeziorsko Reservoir inlet. The three processes, namely sediment deposition, vegetation growth, and pollutant transport, are crucial for the functionality of reservoir. Classical HEC-RAS package is used for the reconstruction of steady flow conditions in the river reach. The transport of admixture is simulated by means of convection – dispersion model with additional elements describing storage of solutes in the floodplains. The results that the degree of maximum concentration decreases as the river bed geometry and vegetation cover are changed.
