Abstract
<jats:p>The paper presents the results of analyzing long-term changes in the maximum runoff of the Kuban basin rivers. It is shown that on the rivers of the upper part of the basin, rainfall-induced water discharges have increased in recent decades under warming climate, which has enhanced risks of flooding in economically developed coastal areas. Probabilistic characteristics of maximum river runoff for all stream gauging stations, as well as parameters of formulas and regional dependencies used to calculate maximum runoff values in the absence of hydrometric observations, are updated using observational data for a long-term period until 2021 inclusive. Possibilities are considered for practical application of the obtained results in order to substantiate adaptation measures aimed at reducing the negative impact of floods.</jats:p>
