| Sumario: | In this study, we analysed gauging stations in the Paraná and Uruguay Rivers, two rivers with excessive run-off which is used for energy and irrigation. We studied their statistical structure and applied spectral techniques to monthly streamflow in order to represent temporal and spatial variability. We also explored the relationship of some of these series with El Niño Southern Oscillation (ENSO) variability. Given these conditions, climatic coherence studies between pairs of stations in the Paraná network, especially for the most frequent waves (less than 2 years), turned out to be redundant. Furthermore, we observed that series for stations in the Paraná River fit to common theoretical distributions, where normality is absent, making this kind of analysis to be redundant as well. The exploratory analysis for this streamflow network, and its extensive records, suggest that in order to improve hydroclimatological studies, reference stations can be selected for each river. © 2018, © 2018 International Association for Hydro-Environment Engineering and Research. |
