The paper presents the results of the water quality of the St. George branch, one of three Danube River distributaries, using the combined physical and chemical analyses from June 2017. Three cutoff meander reaches (the Mahmudia, Upper Dunavat and Lower Dunavat meanders) were selected to assess the water ecological state. The cut-offs of the meanders by navigational canals since 1984-1988 caused significant changes in the distribution of the water discharge. Water samples were acquired throughout several cross-sec...

The quality and quantity of delta lakes- sediment depend on fluvial input and in-situ bio-geo-chemical processes. The present study investigates the quality of lacustrine sediments collected from two lakes - Tataru and Merhei, situated in different hydrodynamic environments within the Danube Delta, Romania, but both connected to fluvial input of water and sediment of the Danube. The following physical and chemical analyses have been carried out on several lake-bottom sediment samples: the main lithological compone...
