ANÁLISE ESPAÇO-TEMPORAL DA VAZÃO NA BACIA HIDROGRAFICA DO RIO VERDINHO

Abstract

This work aims to temporally assess flow variations in the Verdinho River basin. The research addresses the topic of hydrological monitoring, focusing on analyzing flow fluctuations over time. The study's relevance lies in the importance of understanding water behavior for the sustainable management of local water resources, also considering changes caused by human activities. To achieve the objectives, statistical analysis of time series was used, with flow data collected through fluviometric stations installed in the basin. Data analysis was carried out using hydrological modeling techniques and descriptive statistical tools. The results indicate that flows show significant variations throughout the seasons, with peaks during the rainy season and sharp drops during dry periods. It was found that flow patterns are directly related to regional rainfall indices and influenced by human activities, such as deforestation and intensive water use for irrigation. These results contribute to improving water management policies in the region. It is concluded that the Verdinho River basin has a flow dynamic highly sensitive to climatic seasonality and human interventions. The research demonstrated that continuous monitoring is essential to predict extreme events and plan the rational use of water resources. It is suggested that future studies explore predictive modeling to enhance management capacity, considering environmental and social change scenarios.
