2D Hydrodynamic Model Development for a Critical Sector of the Danube River

Abstract This paper aims to develop a high-precision two-dimensional hydrodinamic model of the Danube critical sector extended between Bechet and Corabia (from rkm 678 to rkm 625), using Danish Hydraulic Institute (DHI) Mike 21 software. The Digital Terrain Model (DTM) of the study area was obtained based on LiDAR (Light Detection and Ranging) data, combined with topogeodetic and bathymetric data collected during two field campaigns within the FAST DANUBE Project. Hydrodynamic modeling is mandatory in order to identify environmentally friendly technical solutions to solve the navigability issues on each critical area and to ensure safe conditions for the freight transport along the entire length of the Romanian-Bulgarian common sector of the Danube River.
