The possibility of using the HEC-RAS software for hydraulic calculations of an open network with an assessment of the adequacy of the calculation results in relation to the methods and calculation formu-las used in Belarus is considered. Comparison of the calculation results (obtained in HEC-RAS with the recommended formulas given in the normative, reference and educational literature) showed that the obtained values have deviations from 1 to 20 %. Data analysis allows us to conclude that HEC-RAS can be used as an alternative method for hydraulic calculation of open channels.
