Abstract

Recently in Hungary, drought affects the Drava floodplain more severely than floods. The channelization of the Drava River changed the water budget of the Cún- Szaporca oxbow lakes in the floodplain. The paper presents a 3-D groundwater model for this oxbow of the Drava floodplain to gain a better understanding of the water budget of the whole system under the normal situation and for different lake replenishment scenarios. The model is developed using the finite difference code MODFLOW-2005 and calibrated with a mean error of -0.03 m, and mean absolute error of 0.08 m. Two scenarios for the replenishment of lake were analyzed. Water level is planned to be raised by 0.5 m and 1 m, for the first and second scenario, respectively. As a consequence, an increase of seepage from the lake was found. Around 65 % of the seepage recharges the groundwater system. Such a rise in groundwater table improves the sustainability of the aquifer and serves agricultural and environmental purposes. Additionally, they show the importance of the model for decision makers to select the right future management decisions.
