Intense groundwater flow in the Kozloduy Lowland is related to the formed layered aquifer on the contemporary Danube River terrace. The main factors affecting the groundwater regime are fluctuations of the Danube River, water influx from the south and the recharge as a part of the rainfalls in the area. The drainage system in the central part of the lowland affects the water levels and creates a widespread depression. This forms a disturbed groundwater regime in the area. The impacts of the Danube River for a six-year period (from 2007 to 2012) have been estimated. The groundwater balance elements were analyzed, based on transient numerical model of the lowland. Fluctuations of the groundwater levels are the most significant close to the river at a distance of 300–400 m, reaching as much as 1000 m in the lowland. Oscillation’s amplitude of groundwater levels gradually decreases with distance from the river and as a result of the drainage system abstraction. There is relation between the water stages in the river and the intensity of the drainage flow.

Response of the Danube River Floodplain to Flood Events During 2002-2007 Period The relationship between floods and their geomorphic effect is discussed in this article. Almost every flood event is registered in overbank alluvia. We investigated sediment structures and textures as a response to three flood events occurred during 2002-2007 period on the Danube River floodplain in Bratislava. The change in sedimentation is the effect of floodwater flow energy changeability in the channel and floodplain. Generally, three main phases of energy flow changes of floods are recognised and thus the complete flood record can be expressed as the set of three layers. We also analysed conditions of the overbank sedimentation based on the shape and size of sedimented particles. Results show a relatively high variability of sedimentation processes during floods. The total amount of new overbank sediment accumulated in the 2002-2007 period, its texture characteristics and spatial distribution do not depend only on flood discharge, but also on the drainage basin sources of floodwater and sediment.
