Conceptual hydrological model of Santa Barbara Ecological Station (EEcSB) in Bauru Aquifer System (BAS)

Abstract

Hydrogeological modeling enable to answer several questions capable to describe the spatial and temporal variability of aquifer behavior, such as variations in levels, direction and velocity of flows, water source and available volume. Groundwater management can be benefit by the information generated from the construction of a Hydrogeological Conceptual Model (HCM), looking for data and expert knowledge maximization, using both in a systematic way to obtain answers and knowledge of groundwater dynamics. This study aimed to construct an HCM using spatial analysis techniques applied to environmental variables and water table depths data. From the use of a quantitative and qualitative methodology we search for generating a HCM to describe the Bauru Aquifer System (BAS) dynamics at Santa Bárbara Ecological Station (EEcSB), municipality of Aguas de Santa Barbara/SP, Brazil. The results provide a HCM that allows a series of initial interpretations on the behavior of the underground flow, subsidizing the decision making for the protection of water resources within the boundaries of the EEcSB. It is concluded that discharges through recent underground flows supply the surface drainage present in the area and this underground flow follow the topography towards the major drainages.
