The Elbe River is navigable in the Czech Republic from Pardubice to the Czech/German border. From Pardubice to Ústí nad Labem, the Elbe is navigable by a cascade of 24 weirs. The last 42 km of the Elbe River between Ústí nad Labem and the Czech/German border are navigable only by historical river training works. The aim of this paper is to identify and map problematic sections with low water depths that restrict navigation. These sections are dangerous at low flow rates when the navigation depth is low and ships can navigate with limited draft. This reduces the capacity of the waterway. A 2D mathematical model is used to identify sections with low navigation depth. In the first phase of the research, it is necessary to define an outlet boundary condition at the Czech/German border. In the second phase, the 2D mathematical model is calibrated for the measured water levels and the corresponding flow rates. In the last phase of the research, problem areas with low navigation depth at low flow rates are identified. Based on the identification, it is possible to design river training works in this section of the waterway.
