The hydrological variability and especially extreme phenomena such as droughts and floods affect natural and human systems worldwide. The Paraná River sub-basin, belonging to the La Plata basin, is of great regional importance, and in recent years extreme events have been observed that have impacted socio-economic aspects of the community. This study compares the series of a relevant hydrological index, calculated from observed flows and unregulated contributions within Argentine territory, at the same reference station. Intense hydrological periods are analyzed in both cases, for droughts and excess water events, for subsequent comparison.

La variabilidad hidrológica y en especial los fenómenos extremos como las sequías e inundaciones afecta a los sistemas naturales y humanos en todo el mundo. La subcuenca del río Paraná perteneciente a la cuenca del Plata, es de gran importancia regional y en los últimos años se han observado eventos extremos que han afectado aspectos socieconómicos de la comunidad. En este estudio se comparan las series de un índice hidrológico pertinente, calculadas a partir de caudales observados y de aportes sin regulación dentro del territorio argentino, en una misma estación de referencia. Se analizan los períodos hidrológicos intensos en ambos casos, tanto de sequías como de excesos hídricos, para su posterior comparación.
