1. Eco-hidrologia integrada ao manejo dos recursos hídricos em áreas úmidas: caso do Banhado do Taim, RS
RESUMO A eco-hidrologia busca integrar os conhecimentos da hidrologia aos da ecologia, criando uma abordagem mais ampla para a compreensão da dinâmica dos recursos hídricos, facilitando o planejamento e as ações de programas de gestão. Uma das formas de integrar hidrologia à ecologia é por meio da elaboração de índices de adequabilidade de hábita

2. Structure and temporal variation of the phytoplankton of a macrotidal beach from the Amazon coastal zone
ABSTRACT The present study aimed to analyze the structure and the temporal variation of the phytoplankton of Ajuruteua beach (Bragança, Pará) and to investigate the influence of environmental variables on the dynamics of this community to provide a basis about the trophic state of this environment. Biological, hydrological and hydrodynamic samplings were p

3. Assembléias de diatomáceas em sedimentos holocênicos no estremo sul do Brasil : reconstruções paleoambientais
This paper describes the diatom assemblages present in a sediment profile in the Lagoa do Peixe, Middle Littoral of Rio Grande do Sul, in order to make the palaeoenvironmental reconstruction and identify periods of increased marine influence and hydrodynamics, as a consequence of changes sea level occurred during the Holocene. The drill core T09 was selected

4. Influência dos modelos digitais de terreno na modelagem de circulação hidrodinâmica 2DH: um estudo de caso
Os modelos digitais de terreno (MDT) consistem na representação matemática computacional da distribuição de um fenômeno espacial que ocorre dentro de uma região da superfície terrestre. A qualidade da representação do MDT está influenciada, dentre outros fatores, pela origem do dado e pelo algoritmo interpolador utilizado. A caracterização da ci

5. A finite element model for the ocean circulation driven by wind and atmospheric heat flux
A finite element model for solving ocean circulation forced by winds and atmospheric heat fluxes is presented. It is vertically integrated 1 1/2 layer model which solves the motion and continuity hydrodynamic equations coupled with the advection-diffusion transport equation for temperature. A space-time Petrov-Galerkin formulation is used to minimize the und

6. Numerical model of oil spill as an environmental management method in contingency plan, applied to São Sebastião channel (SP). / Modelagem numérica do comportamento de derrames de óleo como método de gestão ambiental, em planos de contingência, aplicada ao canal de São Sebastião (SP).
The application of numeric models for analysis of oil spill in the coastal environments becomes one of the most important ways to understand the behavior of the oil in this case of impact, giving subsides to the prediction of the displacement of the patches and allowing best efficiency in the control of the extension of the impact agent. These assumptions gi

7. A erosão costeira e sua influência sobre a atividade petrolífera: alternativas sustentáveis na mitigação de impactos ambientais
The study area consist in high sensitivity environments located on the northern coast of Rio Grande do Norte, Northeast Brazil. The barrier island are the main geomorphological features on the coastal landscape, being naturally instable and surrounded by industrial activities like oil fields, salt industry, shrimp farms and urban areas sometimes installed pa

8. Estudo da circulação hidrodinâmica e da dispersão de óleo na zona costeira entre Macau e Galinhos RN
This paper presents a study on coastal hydrodynamics and the spread of an oil spill in waters off Macau and Galinhos, on the east coast of the state of Rio Grande do Norte in Northeast Brazil. This area has a very marked coastal dynamic owing to the complexity of its geomorphological features, developed in a regime of semidiurnal mesotides involving reefs, s

9. 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

10. Análise crítica da utilização de modelagem matemática na avaliação da dispersão de efluentes leves no litoral da Baixada Santista ( Estado de São Paulo). / The analysis of mathematical models in the assessment of effuents dispersion in Baixada Santista coastline (State of São Paulo).
The prediction of the hydrodynamic water circulation and pollutants dispersion, mainly in coastal areas, has been a problem that engineers have been facing. This is due to the increase environmental impacts that involve coastal engineering work and management. The usage of mathematic modeling as assessment tool is necessary for these studies. The main purpos

11. DiagnÃstico geoquÃmico e geocronologia do sistema estuarino-lagunar do roteiro Alagoas
The estuarine lagoon system of the Roteiro is located in the central coast of Alagoas, showing the largest continuous area of preserved mangroves of the State of Alagoas. This ecosystem has been heavily impacted by various anthropogenic activities such as urbanization, the cultivation of oysters, the gas production, the manufacture of cement and the cultivat

12. Reconstituição paleoambiental das enseadas do Flamengo e da Fortaleza, Ubatuba, S.P., durante o Holoceno, inferida a partir da variação das associações de foraminíferos / Paleoenvironmental reconstitution of Flamengo and Fortaleza bays, Ubatuba, SP, during the Holocene, inferred from the variations of Benthic foraminifera associations
Variations in Holocene environments in the marine bays of Flamengo and Fortaleza at Ubatuba, State of São Paulo, southeast Brazil, were detected in cores UB1 and UB3, respectively, on the basis of the distribution pattern of foraminiferal associations and their correlation with abiotic characteristics of the sediments. Correlations were then established bet
