SUMMARY:

Water resources are indispensable for many human activities. Over the last few years, the availability of surface water has changed due to changes in the use and soil of watersheds. Knowledge of changes in the flow regime of a watercourse, as well as the causes that caused them, are important for the maintenance of aquatic ecosystems, as well as for the preservation of the environmental services provided by rivers. Thus, the objective of this work was to evaluate the existence of a relation between climate changes, verified through rainfall, and hydrological changes in tributaries of Paraíba do Sul, an important basin in the Brazilian Southeast, using statistical methods. These compared 20-year hydrological data series defined in the periods 1955-1975 and 2001-2021. An increase in rainfall was identified in the Preto River basin, which also showed changes in its flow regime, indicated by indices of magnitude, frequency and rate of change, in different ways along its course. The behavior of these indices indicates a probable relation between surface runoff from headwater regions and the effects of climate change, while flows from more downstream regions are under the effect of changes in land use and occupation. Thus, future water resource management actions can prioritize strategies that minimize the main sources of alteration in the flow regime, necessary for maintaining the integrity of this ecosystem, in order to guarantee its permanent use in an ecologically, socially and economically viable way.
