The extreme discharges in the Danube Lower Basin, highlighted by the Generalized Extreme Value theory, were analyzed by their internal and external drivers. For the former, some large and regional scales climate indices, such as the North Atlantic Oscillation (NAO), the Greenland-Balkan Oscillation (GBO), and the Palmer type drought indices, respectively, were used. For the latter the sunspot number (SSN) time series was considered.

Wavelet coherence for multiple variables, different types of filters and regression models were applied.

The results obtained in this study depend on the season, and can be beneficial for different decision-makers for a good management of water resources in case of extreme events.
