AB  - The subject of this study is an approximately 300 km long Middle Danube River reach that
spans from river kilometer (rkm) 1581 in Hungary to (rkm) 1255 in Serbia. The observed drying of
floodplains in Hungary some thirty years ago initiated the hydrological studies. However, problems
related to the navigation route maintenance of the Danube River and those in the water supply of
irrigation and drainage canal networks are now present in the whole free-flowing middle Danube
region. The study aims at investigating the correlation between the observed water level decrease
and recorded incision of the river bed at gauging stations and the indirect estimation of the long-term sediment transport along the sand-bed reach based on the surveillance cross-sections’ data
collected during regular monitoring surveys on the navigable Danube. It starts with hydrological
analyses of the 70-year-long time series of water level and discharge yearly data and continues
with morphological and correlation studies. It ends with the estimation of sediment transport. The
decreasing trend in water levels and the increasing trend in cross-sectional areas are persistent. There is a linear correlation between the two. Longitudinal changes in sediment transport indicate the existence of both degrading and aggrading riverbed reaches.

AB  - This work is a continuation of works by Goda et al. (2007) and Tamás et al. (2021) that were prompted by the drying of floodplains and problems in the water supply of irrigation and drainage canal networks in the whole middle Danube region. Previous works focused on hydrology and showed a constant lowering of water levels, which indicated the deepening of the riverbed. In the present study, the relationship between indicators of morphological changes and the decrease in low water levels at gauging stations (GS) is sought. At this stage, results confirm a continuous deepening of the riverbed. Despite smaller correlation coefficient values between low water levels (Zmin) and percentage increase in the cross-sectional areas in the sand bed part of the investigated reach, the linear decreasing trend in Zmin is evident.
