Resumo
Fenômenos geográficos apresentam indexação temporal e espacial. Temporal pela dinâmica do processo que se altera ao longo de um período ou sob determinada influência. Espacial pela maneira com que se distribui ao longo do território. Diversas são as condicionantes que podem induzir comportamentos e padrões nesses fenômenos em bacias hidrográficas, como pedoformas, compartimentação geomorfológica, canais de drenagem, geologia, clima, entre outras. A maneira com que dados de monitoramento de recursos naturais são tratados sob o ponto de vista geoespacial pode determinar de forma definitiva o resultado final das feições que se deseja representar e dos mapas obtidos. E por consequência toda inferência que se deseja obter a respeito de determinada região de forma que venha a contribuir nos planos de bacias e gerenciamento dos recursos hídricos. O objetivo desse trabalho foi estimar a recarga das águas subterrâneas por meio do método da Variação da Superfície livre (WTF) na Estação Ecológica de Santa Barbara (EEcSB), situada no município de Águas de Santa Bárbara, sudoeste do estado de São Paulo, a partir de dados de monitoramento. Foram utilizados dados de monitoramento climatológico e hidrogeológico para estimar a recarga das águas subterrâneas no período de 2014/2016. Para isso, foi testada uma metodologia baseada no princípio de calcular antes/interpolar depois, onde a recarga foi estimada pontualmente pelo método da flutuação da superfície livre (WTF) para cada poço de monitoramento. Os resultados do trabalho foram interpolados pelo do Inverso do quadrado da distância (IDW) demonstrando graficamente como o fenômeno foi especializado e qual foi a taxa de recarga para a área de estudo.
Geographical phenomena show time and space indexation. Time indexation for the process dynamics, which, changes itself through the period or under influence. Space indexation for the manner that it distributes itself in the territory. The factors are diverse and they an induce behavior and patterns in watershed phenomena, like pedofomrs, geomorphological compartmentation, rivers, streams, geology, climate, among others. The manner, which the natural resources monitoring data, is treated by geospatial look can determine the final result of the components which is aimed to represent and obtained maps. Thus, by consequence, all the inference which is desired to be obtained about a determined region for contributing in watershed plans and water resources management. The aim of this work was to estimate the groundwater recharge via Water Table Fluctuation Method (WTF), from monitoring data, in Santa Barbara Ecological Station (EEcSB), located in Águas de Santa Bárbara county, southeast of Sao Paulo state. It was used climate and hydrogeological monitoring data to estimate the groundwater recharge in the period of 2014/2016. It was tested a methodology based in calculate first/interpolate after, where the recharge was estimated by water table fluctuation method (WTF) for each monitoring well. The results were interpolated by the inverse distance weighting (IDW) method showing in graphs how the phenomena was spatialized and what was the recharge rate presented in the study area.
