The goal of this thesis is to determine the impact of the land use change on the water cycle components of the Upper Paraná River Basin (CARP), in the Upper Paraná Atlantic Forest (BAAPA). The analysis of vegetation indexes suggests that most of the CARP in Brazil had none forests in 1982. On the other hand, it is observed that the greatest losses of BAAPA occurred in Paraguay in the period 1980-2000. In order to analyze the effect of these changes on the water balance, the Singular Spectral Analysis method is applied to the historical series of precipitations (P), air temperatures (T) and water flows (Q) of two sub-basins of the CARP. The selected sub-basins present different and suitable patterns of deforestation to analyze this process. In each study area, the study variables were systematically analyzed through time and at different spatial scales to find de principal component of them. In all the analyzed cases it was found that the Q series have a low frequency component and 2 oscillatory components. The Q low frequencies component show statistically significant increases from the year when regional deforestation intensifies. That is to say that in Brazilian basins Q increased from 1970, whereas on Paraguay basins Q increase is observed around 1980. P presents a trend and oscillatory components similar to those of Q. Finally, the variations of the low frequency signals balance in the larger basins were analyzed. Thus, the low frequency evapotranspiration (ET) series is obtained, which reflects the different land use change processes that occurred in the CARP during the 1950-2000 period.Palabras clave – provistas por el repositorio digital
