Abstract
The article considers one of the main parameters while conducting water management calculations – the roughness coefficient. Up-to-date assessment of its value is carried out according to special tables or by calculation. Article presents various methods for calculating the roughness coefficient – from the reverse evaluation using the Chezy formula by the measurements to the empirical relations obtained by various specialists on the basis of field studies. In addition, the authors considered formulas for calculating the roughness coefficient based on physics. The results of calculations obtained for such formulas best fit their values obtained in the inverse way from the Chezy formula. The calculation methods presented in the article were tested on the data of gauging station on the river Polist' – near the settlement Podtopol'e for the period of 1954 year and on the river Gozovka – near the settlement Goza for the period 2014...
