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 corre...lation 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.
