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 study presents a detailed analyse of the morpho-dynamic processes of the main two bifurcations of the Danube River within its delta, at Ceatal Izmail and Ceatal St. George. The first bifurcation of the Danube, called Ceatal Izmail; here the river divides into two distributaries: a northern one, the Chilia (Kilia), and a southern one, the Tulcea. Forking to the right at Ceatal Izmail (Mile 43), the Tulcea distributary stretches further to 17 km to the second main hydrographic knot Ceatal Sfantu Gheorghe (St. Ge...
