Abstract

Monitoring is the most efficient tool for the continuous observation, which, thanks the technology used, can be transformed into the observation of the behavior of hydrological variables in real time. Because of this versatility and the information produced, monitoring can support the Integrated Water Resources Management (IWRM) in adapting to climate change and in planning the regional socio-economic development. Therefore, the historical series (2000-2022) for the climatic variables’ precipitation, surface runoff and evapotranspiration from global climate models products of remote sensing, and the climatological water balance were evaluated for the Baixo Pardo Grande watershed (UGRHI 12). The UGRHI 12 is located in the northeastern part of the State of São Paulo. Furthermore, the historical series of water level monitoring of two artesian wells from the Bauru Aquifer System (BAS), a sandstone and free aquifer in the study area, were used to better understand the seasonality and interaction between the atmospheric and continental reservoirs of the hydrological cycle.
