Due to climate change and its impact in the precipitation, it is necessary to continue the studies of extreme events. This work focuses on the ones that take place in river?s discharges. We propose to analyse extreme streamflow events in the La Plata Basin,particularly in Parana and Uruguay rivers. We start by obtaining the diphase between NIÑO 3.4, SOI indices and seasonal discharges. We leverage these results and compute the probability of joint occurrence of extreme events and the corresponding return period. Moreover, we estimate the probability of extreme streamflow events, given values of the index from previous period.
