The paper focuses on the assessment of second-order explicit numerical scheme for unsteady flows in sewers. In order to simulate the pressurized flow the 'Preissmann slot' concept is implemented. For simulation of the transcritical flow the original and improved McCormack scheme is used. The calculated results are compared with numerical solutions and laboratory measurements published in the technical literature. Moreover, the aim of this paper is to present the comparison between calculated and measured at the hydraulic laboratory of Gdańsk University of Technology (GUT) pressure values which were observed during experiment for water flow with pipe pressurization. The analysis proves that proposed numerical approach to flow simulation is a sufficiently accurate and reliable technique for prediction of basic storm sewers flow parameters.
