O Sistema Aquífero Bauru foi avaliado usando, condutividade hidráulica, coeficiente de armazenamento, nível estático, vazão, profundidade de poços e dados de qualidade de água. Os poços que explotam o Bauru foram analisados em termos de estrutura técnica e perfil geológico. Os resultados mostram que, na área, o Bauru tem características hidráulicas similares ao restante do Brasil, indicando boa capacidade para produção de água, conforme mostram as vazões dos poços tubulares. As suas águas são ácidas, alguns locais apresentam teor de ferro acima do VMP, porém podem ser consideradas potáveis. Os poços tubulares menos de 10% atendem os critérios técnicos das normas da ABNT, o que pode está contribuindo para alguns problemas locais de qualidade dessas águas, como turbidez, ferro, etc. O conhecimento e os dados produzidos constituem uma ferramenta indispensável para embasar a política de gestão de recursos hídricos nesta cidade e a realização de campanhas educativas voltadas ao uso sustentável dessas águas. / In this work the hydrogeological characterization of the Bauru Group was held in the urban area of Primavera do Leste, using existing data from wells, geology, morfopedologia and vertical electrical sounding. The Bauru Aquifer System was evaluated using hydraulic conductivity, storage coefficient, static water level, discharge, depth of wells and water quality data. The wells that explotam the Bauru were analyzed in terms of technical structure and geological profile. The results show that, in the area, Bauru is similar hydraulic characteristics to the rest of Brazil, indicating a good production capacity water, as shown the discharge wells. Its waters are acidic, some places have iron content above the VMP, but can be considered potable. The wells less than 10% meet the technical criteria of ABNT, which can is contributing to some local water quality problems such as turbidity, iron, etc. The knowledge and data produced are an essential to support the policy of water management in the city and performing on the sustainable use of these waters educational campaigns tool.

Ce manuscrit de thèse présente une nouvelle approche pour caractériser qualitativement et quantitativement la localisation et les propriétés des structures dans un aquifère fracturé et karstique à l’échelle décamétrique. Cette approche est basée sur une tomographie hydraulique menée à partir de réponses à une investigation de pompages et interprétée avec des méthodes d’inversions adaptées à la complexité des systèmes karstiques. L’approche est appliquée sur un site karstique d’étude expérimental en France, une première fois avec des signaux de pompage constants, et une deuxième fois avec des signaux de pompage harmoniques. Dans les deux cas, l’investigation a fourni des réponses de niveaux d’eau de nappe mesurés pendant des pompages alternés à différentes positions. L’interprétation quantitative de ces jeux de réponses consiste à les reproduire par un modèle avec un champ de propriété réaliste adéquat généré par inversion. Les méthodes d’inversions proposées dans ce manuscrit permettent de reconstruire un champ de propriétés hydrauliques réaliste en représentant les structures karstiques soit par un réseau généré par automates cellulaires, soit par un réseau discrétisé. Les résultats d’interprétations obtenus sur le site d’étude expérimental permettent d’imager les structures karstiques sur une carte et de « lire » leur localisation. De plus, les résultats obtenus avec les réponses à des pompages harmoniques tendent à montrer le rôle de la fréquence du signal sur les informations portées par les réponses. En effet, les fréquences plus élevées caractérisent mieux les structures les plus conductrices, alors que les fréquences plus faibles mobilisent des écoulements également dans des structures karstiques moins conductrices. / This thesis manuscript presents a novel approach to characterize qualitatively and quantitatively the structures localization and properties in a fractured and karstic aquifer at a decametric scale. This approach relies on a hydraulic tomography led from responses to a pumping investigation and interpreted with inversion methods adapted to the complexity of karstic systems. The approach is applied on a karstic experimental study site in France, a first time with constant pumping signals, and a second time with harmonic pumping signals. In both applications, the investigation resulted in groundwater level responses measured during alternated pumping tests at different locations. The quantitative interpretation of these sets of responses consists in reproducing these responses through a model with an adequate realistic property field generated by inversion. The inversion methods proposed in this manuscript permit to reconstruct a realistic hydraulic property field by representing the karstic structures either through a network generated by cellular automata, or through a discretized network. The interpretation results obtained on the experimental study site permit to image the karstic structures on a map and to‘read’ their localization. Furthermore, the results obtained with the responses to harmonic pumping tests tend to show the role of the signal frequency on the information carried by the responses. In fact, higher frequencies better characterize the most conductive structures, while lower frequencies mobilize flows also in less conductive karstic structures.
