1. Circulation and suspended sediment dynamics in a tropical estuary under different morphological setting
ABSTRACT Estuarine processes are directly related to the interaction of its forcing conditions with the local morphology. In this study we assess the implications of the opening of a new inlet on the hydrodynamics and suspended sediment concentration (SSC). A set of physical parameters have been measured in the Itanhém river estuary, a small, shallow and ma

2. Observação do transporte de sedimentos em suspensão ao longo do Canal Norte do rio Amazonas durante condições de baixa descarga (outubro 2008) / Observation of suspended sediment transport along North Channel of Amazon river during low discharge (October 2008)
The Amazon river, located in northernBrazil, discharges between 80,000 and 250,000 m3s-1 of water onto the adjacent shelf, creating a plume of brackish water that extends hundreds of kilometers away from the river mouth. This river also carries a large amount of fine sediments to the ocean where fluid mud has been found in the topset and upper foreset layers

3. A new look into the small-scale dispersal of free-living marine nematodes
We tested experimentally the hypothesis that prevailing locomotion/feeding strategies and body morphology may lead to more active dispersal of free-living marine nematodes, besides passive transport. Neutral Red was applied to the sediment inside cores and the red plume formed during the flood tide was divided into near, middle, and distant zones. At 0.5 m a

4. Modelagem numérica da dinâmica do sistema estuarino Caravelas - Peruíbe, BA / Numerical modeling of the Caravelas-Peruíbe (BA) estuarine system
O presente trabalho visa caracterizar, através de experimentos numéricos, a hidrodinâmica e o transporte de sedimentos em suspensão no sistema estuarino de Caravelas e Peruípe sob diferentes condições forçantes. O sistema é formado por canais que estabelecem a conexão entre os rios Caravelas e Peruípe. Dados de nível de água e velocidade de corr

5. Hydrodynamics and suspended sediment transport in the Camboriú estuary - Brazil: pre jetty conditions
As trocas de água e materiais através das desembocaduras de estuários são de difícil quantificação e são de fundamental importância para o entendimento do funcionamento de estuários e da zona costeira. A hidrodinâmica e transporte de sedimentos em suspensão no estuário do rio Camboriú foram estudados através da realização de duas campanhas d

6. Processos dinÃmicos e evolutivos da zona costeira de Itamaracà por sensoriamento remoto e medidas in situ
The coastal zone of Itamaracà is like a highly dynamic environment where land and oceanic processes interact altering frequently coastal characteristics. In this context, this current study examines the responsible processes of such changes from the development and application of methodologies, which includes digital image processing and the obtaining of in

7. AVALIAÇÃO DA PRODUÇÃO DE SEDIMENTOS EM EVENTOS CHUVOSOS NA BACIA HIDROGRÁFICA EXPERIMENTAL DE SÃO MARTINHO DA SERRA. / EVALUATION OF THE PRODUCTION OF SEDIMENTS IN RAINFALL EVENTS IN SÃO MARTINHO DA SERRA EXPERIMENTAL BASIN
The intense use of the soil and natural resources emphasizes the importance of researching fields related to sediment transport and sediment deposition in catchments. Consequently sediment yield is object of concern in situations regarding the land se and water resources management. The main objective of this research was to evaluate the sediment yield at Sa

8. Análise e estimativa do transporte de sedimentos em suspensão durante eventos chuvosos / Analysis and estimation of suspended sediment transport throughout rainy events
Este trabalho tem por objetivo monitorar o transporte de sedimentos suspensos provenientes da bacia hidrográfica do Rio Taquarizinho, durante os eventos chuvosos ocorridos no período compreendido entre 2005 e 2007. Por meio de levantamento de dados históricos, foi avaliado a evolução das cotas linimétricas, vazões e perfis transversais ao longo das ú

9. Avaliação de impactos ambientais nos tributários do lago Paranoá, Brasília - DF
The high level of urbanization in Distrito Federal in Brazil is contributing to modify the environment particularly the quality of surface water resources. The historical of environment aggression to the Paranoá Lake through urban expansion, land use and land occupation, is studied as environmental changes. In this work, physical-chemistry conditions and ge

10. The study transport of suspended sediment in the descoberto river watershed. / Estudo do transporte de sedimentos em suspensão na Bacia do Rio Descoberto
In this study, sedimentometric data were collected in streams located upstream and downstream the Descoberto reservoir, with the objective of improving the knowledge about the sediment transport in this watershed. Monthly data collection campaigns from June-2005 to February-2006 were carried out to determine suspended sediments loads using a depth sampler, t

11. AplicaÃÃo de um modelo paramÃtrico para a estimativa do transporte de sedimentos arenosos na Bacia de Campos / Application of a parametric model to assess the sandy sediment transport in the Campos Basin
Studies about sediment transport processes that occur in the Campos Basin are of great importance, since they can contribute for example to improve the comprehension of how the sedimentary deposits, that are potential oil reservoirs, take form or to provide elements that can help to understand the changes in marine bed forms on areas where submarine pipeline

12. SEDIMENT TRANSPORT CHARACTERIZATION IN A SMALL URBAN STREAM IN SANTA MARIA-RS / CARACTERIZAÇÃO DO TRANSPORTE DE SEDIMENTOS EM PEQUENO RIO URBANO NA CIDADE DE SANTA MARIA RS
This paper presents the results of the sediment transport assessment in a small urban stream in Santa Maria city, RS. Liquid and solids discharges were measured and the bed material was collected during thirteen raining events, between December 2003 and November 2004. The laboratory tasks included the particle size analyses and the sediment concentration. Th
