✦ Synopsis

A wavelet ®lter was employed for removing the strong annual wave in the Atuel river runo data to analyze for other wavelength phenomena of interest and to examine the in¯uence of the ENSO events. After this removal, the in¯uence of ENSO signal in dierent frequency bands and indications of climatic changes in bands larger than 10 years could be observed. Other signi®cant phenomena were also observed. As the Andean Argentinean rivers in the Cuyo region have signi®cant similarities, the conclusions about the Atuel river could be extended to other rivers in this region.
