Abstract:The article discusses the considerable changes in hydrometeorological conditions that occurred in the Danube River basin over the period from the late XX century to the early XXI century. Mention is made of the air and water temperature rise, softening of ice conditions, and, above all, the noticeable increase in the river water runoff. Particular attention is given to the recent extreme hydrological events in the Danube River basin: the disastrous rainfall flood that occurred in August 2002, the extremely high spring-summer floods in 2006 and 2010, and the extraordinary low-flow period in summer 2003. The meteorological reasons for these events have been analyzed. Specific features in the development and transformation of flood waves along the Danube River are discussed in detail, including the impact of the Iron Gate-1 Reservoir on these processes.
