I am graduated in Geology from Universidade Estadual Paulista Júlio de Mesquita Filho (1988) and PhD in Geosciences and Environment from Universidade Estadual Paulista Júlio de Mesquita Filho (2007). I had been working in several drilling companies, prospecting groundwater in several regions from Brazil and Uruguay. I am currently Researcher III at the Center for Environmental Studies at UNESP - Rio Claro Campus. Coordinator of the Hydrology and Environmental Isotopes Laboratory (LARHIA), and my main research focus are in hydrogeology, isotopic hydrology, hydrochemistry and water resources management. I am a consultant for the International Atomic Energy Agency, and currently coordinator of the Postgraduate Program in Geosciences and Environment at IGCE-UNESP Rio Claro (Source: Lattes Curriculum)

The effects on water storage, quality and movement through the continental compartments of hydrological cycle, resulting from climate change and urbanization processes have been observed and described in different parts of the world, however their effects in Central Amazonia, where the municipality of Manaus is located, can be intensified due to the disordered processes of land use conver…
In a global scenario of climate change, the sustainable use of water resources requires an understanding about the mechanisms involved in the water movement and storage within the hydrological cycle compartments, since of water scarcity and increased competition for more water supply have been occurring. Future management solutions should consider the climatic factors involved in rainfall…
Sustainable use and management of aquifers and their interaction with rivers and lakes requires qualitative and quantitative assessment of aquifer hydrogeology and dynamics, and the use of conceptual and/or hydrologic models. Hydrologic observations in addition to estimation of aquifer properties are needed for numerical groundwater models. Recently, isotope techniques such as groundwater…

In the Brazilian Northeast, groundwater represents the main source of water. In the scenario of climate change and demographic growth in semi-arid regions, knowledge about flow conditions, storage and hydrogeochemical evolution of groundwater contributes to better management of water resources in these regions. The record of overexploitation and salinization in the Açu Aquifer, located in…
The study area comprises the Açu Aquifer System in its continental portion of the Potiguar Basin, which is located in the northeastern region of Brazil, covering parts of the states of Rio Grande do Norte and Ceara. This aquifer has an extremely and relevant role in supplying water for human use, agricultural and industries in the region. The importance of aquifer has become even more evi…
The Pantanal basin has complex hydrological dynamics that are closelylinked to its structural control and the seasonality of the rainfall regime. Simultaneously,the economic exploitation of natural resources, climate change and the change invegetation cover influence the hydrological dynamics, noticibly the change in wateravailability, the acceleration of erosion / depositional processes,…

Assessments of time series on the variability of the rainfall isotopic composition, over continuous observations, have been widely used to understand the effects of climate change, especially in medium to high latitude areas (temperate climate), but there is a gap in this type of analysis in tropical regions, especially due to the lack of long-term isotopic observations. Thus, studies in …
The Chapada do Araripe, located in the southern region of the state of Ceará, Brazil, is an area of great archaeological, ecological, geological, and paleontological relevance, arousing academic and scientific interest due to its unique characteristics. The region has a high population density and faces significant demands to sustain regional development. In this context, the use of groun…
The determination of the isotopic composition of water has become increasingly relevant in hydrometeorological studies, especially in those related to the rain-forming processes, mainly due to the importance that climate change has in the scientific community. Despite the several numbers of studies carried in tropical regions that are based on the isotopic composition of precipitation, se…

Located in the Brazilian semi-arid region, the Potiguar Sedimentary Basin (PSB) preserves records of the Last Glacial Maximum (LGM) in its carbonates, reflecting changes in rainfall patterns due to the migration of the Intertropical Convergence Zone (ITCZ). Within this basin, the Açu Aquifer is a deep, porous, and semi-confined water source for subsistence and irrigation. Its characterist…
Assessments about time series over continuous observations on the variability of the isotopic composition of rainfall have been used to understand the effects of climate change, especially in temperate climate areas, but there is a gap in this type of analysis in tropical regions, especially due to the lack of continuity in these observations. Thus, studies in tropical regions are extreme…

The hydrological dynamics of the Pantanal, vital for ecosystems and local communities, has had significant impacts due to climate change and economic exploitation, especially by agribusiness. This research internship project abroad proposes the application of the artificial intelligence technique, Long Short-Term Memory (LSTM), to analyze the relationship between river flow and variations…
The stable isotopes of hydrogen (1H/2H) and oxygen (16O/17O/18O) in precipitation are employed as crucial tools in investigating the governing climatic parameters in rain events. In tropical zones, classical isotopic relationships between temperature and precipitation quantity are not evident, underscoring the importance of a meticulous analysis that incorporates a broad range of meteorol…
The interactions among components of the hydrological cycle determine water flow intensity, paths and exchanges between atmospheric, surface, and subsurface reservoirs. Climate inputs, hydrology and geology are conditioned by the mutual adaptation to climate change and land use change. These anthropogenic actions have made rational water use into a complex and integrated challenge. Integr…
