During the past years a progressive change of the climatic conditions has been worldwide observed. This has brought as consequence an increases of the frequency and severity of phenomena like floods and droughts. It is then necessary 10 count on tools that allow making decisions in an informed way. Nowadays a form to evaluate the effect of climatic change on the hydrology of a basin is to use a distributed hydrologic model, which once calibrated and validated is disturbed with changes (% of precipitation change and change in the temperature) obtainedfrom future climatic scenarios. The objective of this work is to model the hydrologic response of an Andean sub-basin of the Biobio River to different climate change scenarios. Results indicate that for most of the modeled climate change scenarios a reduction in the magnitude of monthly and annual average flows is expected, being this variation greater at spring and summer.
