ABSTRACT
Interaction of surface and groundwater in left hand-side floodplain area of the Danube River, surrounded by upper power canal and the Danube River was assessed. Two scenarios have been considered for computational analysis. The first scenario is the current state, where dominant influence on the groundwater regime is given by discharge and water level regime in the branch system. Branch system is fed by inlet structure in Dobrohošť. The second scenario provided in the contribution is a forecast of groundwater regime after a possible construction of planned underwater weirs in the Danube River. Results of numerical modelling solving steady non-linear Boussinesque equation by the finite element method have shown that the groundwater regime in the floodplain area would be improved and the drainage effect of the Danube River reduced or completely neglected.
