Abstract

As the observations show, the hydrological regime of the Vere River, in the warm period of the year, as a result of sudden heavy rains, is characterized by large freshets. Due to global climate change, especially since the 1990s, their number and intensity have increased. Calculation of the maximum discharges of freshets using Chezy formula is mainly given in the form of Table 1. In the article, as an example, the calculation of the discharge of the catastrophic freshet on the Vere River on 14 June 2015 for the adjacent section after the connection of the Napetvrebi ravine is given by 2 methods - using the Sokolovsky and Chezy formulas, and according to the maximum discharge calculated at the Napetvrebi ravine for the laboratory section and for the entire Vere river basin using the relative coefficients of their areas, the values of the maximum discharges of the June 14 catastrophic freshet were obtained in the amount of 477 and 512 m3/s, respectively. In addition, it should be noted that comparing all three results of the maximum discharges at Napetvrebi ravine, it can be seen that they are quite close to each other, which indicates the credibility of the maximum discharges of freshets calculated by us in the laboratory section from the 1990s to the present day using the Chezy formula.
