Streszczenie: The article is focused on comparison of some aspects of 1D and 2D water quality model use for modeling of contaminant spreading in rivers. Properties of numerical models MODI and HEC-RAS were tested at 422 m long reach of the Ondava River. Results showed that HEC-RAS model can be used only for scenario or river reach along which the transverse pollution spreading can be complete. Better choice for this case study represents the model MODI that in 2D schematization shows detailed spatial structure of contaminant distribution in time as well as to specify the exact position of pollutant source outlet that effect the character of pollution cloud downstream transported. The results of simulations have proved that numerical models MODI as well as HEC-RAS model allow a reasonable support in decision making process connected to river water quality management.
