Hydrological and geomorphologic conditions of both sections of the river-beds and the state of their regulation infrastructure were presented in the aspect of existing navigation conditions and causes of their limitations. It was stated that both the river-beds, i.e of the Vistula and the Bug over their analyzed sections, have not fulfilled the requirements determined by the waterway classification standards
