2. MONITORING THE FLUCTUATION OF THE WATER TABLE IN UNCONFINED AQUIFERS FOR EVALUATION OF THE POTENTIAL RECHARGE IN OUTCROP ZONE OF THE GUARANI AQUIFER SYSTEM IN CACEQUI - RS/BR / MONITORAMENTO DA FLUTUAÇÃO DOS NÍVEIS DE ÁGUA EM AQUÍFEROS FREÁTICOS PARA AVALIAÇÃO DO POTENCIAL DE RECARGA EM ÁREA DE AFLORAMENTO DO SISTEMA AQUÍFERO GUARANI EM CACEQUI - RS
This research aimed to estimate the recharge and groundwater water table fluctuation in areas with withdrawals of groundwater and surface water related to the variation of groundwater levels and rainfall events. The two areas of study was inserted within the Cacequi Municipality, which is located in the Rio Grande do Sul state, southwestern Brazil, in the Gu

3. FLUTUAÇÃO DOS NÍVEIS DE ÁGUA SUBTERRÂNEA EM MICROBACIAS HIDROGRÁFICAS DO RIO VACACAÍ-MIRIM / GROUNDWATER LEVELS FLUCTUATION IN VACACAÍ-MIRIM RIVER SMALL WATERSHEDS
The intention in this work is to study (locally) the fluctuation system of groundwater levels in two small watersheds. We selected Rancho do Amaral and Rincão do Soturno small watersheds for being representative of the first order streams which compose the Vacacaí-Mirim river watershed headwaters. Both are located at the border of Paraná Sedimentary Basin

4. Integrated study of geological and geotechnical characteristics for aquifer recharge assessment: São Carlos-SP region / Estudo integrado das características geológico-geotécnicas com vista à avaliação de recarga de aquífero: região de São Carlos-SP
This thesis presents an integrated study of the geological and geotechnical characteristics of São Carlos region which influence the recharge process of the aquifer composed of sandstones of the Botucatu Formation. Among the assessed characteristics, it can be distinguished the parameters of ydraulic conductivity, retention of pollutants and pore distributi

5. Análise estatística da influência da precipitação e de características do solo na variação do nível d´água em área de recarga do aquífero Guarani / Statistical analysis about the influence of precipitation and soil characteristics on the water level fluctuation on recharge area of the Guarani aquifer system recharge
The increasing of water use to different consumes have generated the growing of researches related about groundwater resources. The recharges quantification is a indispensible requirement to management of these resources. The main objective of this research is to analyze the influence of precipitation and soil characteristics on the water level fluctuations

6. Determinação da recarga profunda na bacia-piloto do Ribeirão da Onça em zona de afloramento do Sistema Aqüífero Guarani a partir de balanço hídrico em zona saturada / Determination of the deep recharge in the Ribeirão da Onça pilot basin in the outcrop zone of the Guarani Aquifer System through water balance in the saturated zone
Main objective of this work was the determination of the deep recharge in the Ribeirão da Onça basin through water balance in the soil saturated zone. This basin is located in the outcrop zone of the Guarani Aquifer System (GAS) in the São Paulo State - Brazil and is covered by cenozoic sedimentary soil. The water balance model involved the determination

7. Tridimensional modelling of groundwater flow in an unconfined, shallow aquifer in Parque Ecologico Tiete, São Paulo / Modelagem tridimensional de fluxo de águas subterrâneas em um aqüífero livre e raso: aplicação no Parque Ecológico do Tietê - São Paulo
The importance of studying unconfined and shallow aquifers is verified when taking into account that these aquifers are highly vulnerable to contamination and that they are often located under heavily populated regions. A detailed three-dimensional and transient model, which represents the groundwater flow in an area of an unconfined and shallow aquifer at t

8. O impacto de uma lagoa receptora de efluentes industriais contendo boro em um aqüífero raso / Groundwater impact caused by an industrial effluente lagoon with boron
The boron (B) occurs naturally at low concentrations in surface and ground waters used to human supply and irrigation. Although concentration >1mg/L can cause health and environmental problems, detailed studies on transport and fate of B in aquifers are restricted in Brazil. This study investigated the impacts on groundwater quality caused by an industrial (

9. Balanço hídrico em zona de afloramento do sistema aqüífero Guarani a partir de monitoramento hidrogeológico em bacia representativa / Water balance in the outcrop zone of Guarani aquifer system through hydrogeologic monitoring in a representative basin
O objetivo principal deste trabalho é estimar a recarga direta e profunda do Sistema Aqüífero Guarani (SAG) na bacia representativa do Ribeirão da Onça. Paralelamente são analisados os comportamentos do aqüífero e da evapotranspiração na bacia. A bacia do Ribeirão da Onça apresenta características representativas típicas da região de afloramen

10. Evaluation of hydronamics properties of soil for aquifer recharge estimative / AvaliaÃÃo das propriedades hidrodinÃmicas do solo para a estimativa da recarga do aquÃfero
The increase of the water demand associated with the population growth has awaked to the conscience of the population with respect to the importance of the handling of this limited natural resources. Moreover, also it has been observed that the groundwater reservoirs and the surface water sources are connected ones to the others, and that the use of one can

11. Modelagem computacional e anÃlise da salinizaÃÃo dos aqÃÃferos na Ãrea central de Recife
Groundwater is an important water source either for usual exploitation or to be kept as a strategic reserve, regionally and locally, and it needs to be protected. Groundwater quality depends on social and economic activities, depends on land use, and groundwater contamination has become more frequent. Nowadays salinization is the most common type of groundwa
