Summary:

The article presents the methodology and manner of conducting bathymet-ric measurements carried out to calculate hydrological and bridge construction projects. Sample test field studies were conducted, inter alia, on rivers and inland reservoirs. The work included the elaboration of cross-sections of the river valley within the limits of the levees. The research methodology assumed integration of GNSS, bathymetry systems and in special cases the Total Station instruments. The paper presents examples of the results obtained during the research work at one of the southern Polish rivers.
