| description | Climate changes and anthropogenic
activities in the last centuries have modified the hydro-morphological
characteristics of many rivers, including the Danube River. This study aims
to analyze the hydrological regime of the Danube using data registered at
the Giurgiu station and identify the spatio-temporal adjustments of the
riverbed between Giurgiu and Oltenița along a 151 years interval (1864-
2015), as inferred from cartographic documents and satellite imagery. The
results show major changes in the hydrological regime of the Danube, and
also in the shape of the river channel. After the construction of the Iron
Gates I and II upstream of the study area, the water level and sediment
quantity have greatly dropped. Besides the changes in the hydrological
regime, local anthropogenic interventions (dimming, draining, sand
exploitation) have contributed to changing the watercourse. Through
studying the Giurgiu-Oltenița sector, we can add the Danube River among
other European rivers displaying horizontal stability and a tendency of
incising and narrowing of the riverbed. |
