1. Modelagem hidrológica da bacia hidrográfica do rio Bengalas, Nova Friburgo, RJ, utilizando o potencial de geotecnologias na definição de áreas de risco de inundação.
This research focuses on the hydrological study using the potential of geotechnology into runoff modeling of the Bengalas Basin, whose main river, with same name, crosses the city of Nova Friburgo - RJ, in a south-north orientation. This city, one of the most important in "Região Serrana", suffers often with floods and landslides, which, historical data and

2. Metolologia preliminar de avaliação ambiental, com base no ciclo da água, aplicada ao planejamento urbano em municípios de pequeno porte no Norte do Paraná
Embora haja uma diversidade de procedimentos metodológicos para realização de diretrizes e planejamentos urbanos, estes exibem poucas informações acerca dos critérios considerados para avaliação do meio ambiente. A adoção de estratégia formal para avaliação do meio ao qual se pretende planejar pode criar condições objetivas para a troca de exp

3. Interconnectedness during high water maintains similarity in fish assemblages of island floodplain lakes in the Amazonian Basin
We conducted a study to test the hypothesis that interconnectedness among island floodplain lakes and the adjacent Solimões River during the flood stage of the hydrologic cycle is enough to maintain similarity in fish species assemblages. Gill net samples were collected during high and low water periods for three consecutive years (July 2004 to July 2006) i

4. Avaliação dos impactos ambientais de plantações de eucalipto no Cerrado com base na análise comparativa do ciclo hidrológico e da sustentabilidade da paisagem em duas bacias de segunda ordem / Evaluation of the environmental impacts of eucalyptus plantations in the Cerrado region based on the comparative analyses of the water cycle and landscape sustainability in two small catchments
The present study aims to contribute to the analysis of the environmental impact of eucalypt plantations in the Cerrado region of the southern part of the State of Goiás, Brazil. The analysis were based on the methodology of the General Theory of the Systems and also on the results of hydrologic monitoring of two experimental catchments, which included grou

5. DIVERSIDADE DE PARASITAS DE Pygocentrus nattereri (KNER, 1858) (CHARACIFORMES: CHARACIDAE) DURANTE O CICLO HIDROLÓGICO EM UM LAGO DE VÁRZEA E SEU POTENCIAL COMO INDICADORA DA QUALIDADE AMBIENTAL
O parasitismo pode ser empregado como monitor altamente sensível na detecção de alterações ambientais por fatores antrópicos, contudo as áreas alagáveis amazônicas apresentam alterações sazonais naturais regidas pelo pulso de inundação, tendo reflexos diretos na estrutura e composição das espécies de parasitas e conseqüentemente em seu ciclo

6. 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

7. AvaliaÃÃo ambiental e percepÃÃo dos usuÃrios sobre os efeitos das obras de proteÃÃo de costa nas praias da Casa Caiada (Olinda) e Janga (Paulista)
The coastal zones and special the beaches are dynamical and fragile regions in a continuous change. The high population concentration in these areas results in a pressure increment upon natural resources and increased risk of environmental degradation. The coast of the Sate of Pernambuco, is experiencing coastal erosion that has many times being mitigated wi

8. Dinâmica do uso dos recursos hídricos nas bacias do ribeirão Entre Ribeiros e do rio Preto, afluentes do rio Paracatu / Water resources use dynamics in watersheds of Ribeirão Entre Ribeiros and Rio Preto, tributaries of the Paracatu River
From times past, humanity confronts problems of environmental degradation. The environment, which always performed efficiently its function of filtration, today finds itself excessively overburdened by human activities: it suffers the risk of its resources exhausting, not being able in certain situations to recuperate itself and needing the help of man.

9. Land use change and hydrologic behavior analysis in the Preto river and Entre Ribeiros creek basins / Mudanças no uso do solo e comportamento hidrológico nas bacias do rio Preto e ribeirão Entre Ribeiros
The water resources planning and management have the objective to discuss and propose solutions for the watersheds problems looking for the sustainable water use in the urban and rural areas. The relationships between the land use and water resources have been marked by the failure, with environment significant damages, what has transformed in losses for all

10. Survey of one Inceptisol soil attributes influenced by different management system of rice crops in North of Italy / LEVANTAMENTO DOS ATRIBUTOS DE UM INCEPTISOL INFLUENCIADOS POR DIFERENTES SISTEMAS DE CULTIVO DE ARROZ NO NORTE DA ITÁLIA
Considering FAO data that indicate that more than 90% of rice production in the world was to human feeding, become more and more important studies to search improve the rice yields index in sustainable form. Apart from this aspect, rice crops exploration required constant management of submersion water and special care relating to criterion for contamination

12. Propostas para gestão integrada dos recursos hídricos na bacia hidrográfica do rio Jardim DF.
The management of the water resources should be based on technical, scientific, political and cultural criteria. The administration of the water should consider a participative approach, involving the administration and the development of the control actions, including the participation of users, planners legislators in all of the levels, being necessary an
