Abstract Climate change suggested by several studies from few decades ago to recent days is becoming more evident in scenarios of temperature rise for the next hundreds of years. Along with these changes, there are also indications of the increase in the frequency of extreme events and/or intense atmospheric phenomena related to these changes. Although these events are recurrently confirmed with rainfall gauges measurements, they are still limited in terms of the spatial representativeness of these data, often interpolated over large areas. In this sense, this study aims to perform a detailed survey of fluviometric data, taken as more homogeneous measures of the spatial distribution of precipitation. In this way, monthly flow measurements of fluviometric stations in the State of São Paulo will be analyzed in terms of its anomaly, and also relating it to the rainfall estimates from satellite data using the so called CHIRPS (Climate Hazards Group InfraRed Precipitation with Station data). Additionally, trend values will be obtained for the complete time series and for events with more expressive return times, seeking to relate these values to the climate change, as well as to changes in land use in terms of the influence of urban areas. In this sense, the study intends to contribute to a better understanding of the impacts of climate change and land use (in a simplified way) on the fluviometric regime. | |
