The sector is located on the Danube at Mile 43, where the river branches into Chilia and Tulcea tributaries. Therefore, three monitoring topo-bathymetric profiles (2018 and 2019) were performed on Danube (Mm 43), Chilia (Km 114) and Tulcea (Mm 42.5), under circumstances of high and low water levels. On the Danube (Mm 43), an asymmetry of the valley (right bank) ...
