Development of a Bathymetric Model for Danube Bala Branch-Old Danube Bifurcation

The study area is of particular importance in terms of the morphological complex processes of the riverbed. Bala branch is defined by intense hydro morphological dynamics areas. At the same time, Old Danube is characterized by sediment deposition processes, as evidenced by the presence of numerous islands and sandbanks, with negative implications for navigation. In this context, in order to create hydrodynamic and morphodynamic models using Delft3D software, it is necessary to develop a bathymetric model that allows to provide results that are in line with reality. At the basis of the bathymetric model are the results obtained from the single beam and multi-beam measurements and the optimized grid which was refined in the hydrotechnical construction area
