18. Fatoração QR como ferramenta para a determinação de poços principais em redes de monitoramento de aqüíferos freáticos
Monitoring networks of piezometric motion are increasingly used for evaluation and management of aquifers. A pivoted version of the QR factorization was used in four networks, with the purpose of determining principal wells. One network is located at river Jardim watershed, at the east portion of Distrito Federal, Brazil, and the other three are located in s

21. Caracterização da comunidade bacteriana em água subterrânea contaminada com tetracloroeteno / Characterization of the bacterial community in groundwater contaminated with tetrachloroethene
Tetrachloroethene (PCE) is one of the most important contaminants of groundwater, since it is highly toxic and potentially carcinogenic. The bacterial communities of PCE contaminated groundwater and the diversity of bacteria capable of degrading this contaminant are barely known. The objective of this work is to compare the structure of bacterial communities

22. Isotope characterization of the hydrologic cycle components in four sub-basins of the Piracicaba river basin (SP) / Caracterização isotópica dos componentes do ciclo hidrológico em quatro sub-bacias pertencentes à bacia do Rio Piracicaba (SP)
This project had the objective to investigate the oxygen (?18O) and hydrogen (?D) isotopic variation of shallow unconfined aquifers in four regions, in transects defined from the river to the limit of the drainage area. The transects were established within a topographical gradient in four sub-catchments of the Piracicaba river hydrographic basin. The popula

23. 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
