Análisis espacio - temporal de la precipitación en la cuenca alta del río Santa Rosa

Abstract

The space-temporal analysis of precipitation in the upper Santa Rosa River basin addresses how rainfall varies geographically over time. The study employs linear interpolation methods and time series analysis to examine the spatial variability and seasonality of precipitation, using 20 years of historical data. The results reveal a notable seasonality: more homogeneous rainfall in the wet season (January to April) and specific concentrations in the dry season (May to December). A heterogeneous spatial distribution was observed, with areas of higher precipitation in specific areas, while others recorded significantly lower values. Furthermore, the stationarity analysis (Dickey-Fuller test) confirmed that interannual fluctuations in precipitation remain stable, although influenced by climatic phenomena such as El Niño and La Niña. These findings contribute to improving the understanding of the hydrological cycle and inform sustainable water management strategies in the region.
