Diversity and habitat preference of macroinvertebrates were studied in Macaé River basin, Rio de Janeiro State, Brazil, along its longitudinal gradient. We selected stream reaches corresponding to 1st, 2nd, 4th, 5th and 6th orders. A Surber sampler was used to collect four macroinvertebrates samples of each substrate (sand, litter in pool areas, stones, and litter in riffle areas) during the three sampling periods, defined based on the rain regime: April (end of the rainy season), July (dry season), and October (beginning of the rainy season). We identified 46,431 specimens corresponding to 117 taxa. Analysis of diversity numbers (both for family or genus level) indicated that all insect taxonomic orders had higher numbers on 2nd order stream reach, except for Ephemeroptera, on 4th order. However when considering morph-species taxonomic level, the higher diversity number occurred on 4th order stream. The highest richness and diversity numbers were found at the dry season. Considering habitat preference, both litter in pool areas and litter in riffle areas had the highest faunal richness.

The present study records the first occurrence of the threatened armoured suckermouth catfish Pareiorhaphis garbei (Ihering, 1911) in São João river basin and also its presence in four conservation units in the coastal basins of Serra dos Órgãos mountains, Rio de Janeiro state, Brazil. In São João river basin, P. garbei was only captured in a single locality at 111 m a.s.l., consisting in the lower registered altitude for the species, previously found in high altitudes, usually above 800m.

The classic definition of the term Hydrometry refers to the study dedicated to the collection and analysis of hydrological variables. The main objective of hydrological studies is to subsidize projects involving water resources, focusing on their use, such as non-water supply, power generation, irrigation, waterways, effluent dilution, sports and tourism. Thus, in order to perform a successful network planning considering multiple demands and to follow different types of occurrence in a given river basin, it is important to design the hydrological monitoring based on all the actions resulting therefrom, on the physiographic characteristics of the basin under study and on the developed activities. In addition, hydrological monitoring should produce accurate information and continuous operation. Therefore, the present study aims to compile guidelines recommended by the National Water Agency, the Brazilian agency responsible for the implementation of the National Water Resources Policy and the National Water Resources Management System. This study also aims to develop a proposal for the planning of the basin's hydrological network of São João River Basin, located in the mesoregion of coastal plains of Rio de Janeiro State. With new technologies support, it focuses on the monitoring of sediment transport, which is fundamental in the decision making regarding future actions of environmental recovery in the basin. Utilizing detailed information, it was possible to verify that insufficient monitoring is occurring in the basin and to produce a set of recommendations for water resources management based on hydrological monitoring.ResumoA definição clássica do termo Hidrometria se refere ao estudo dedicado à coleta e análise de variáveis hidrológicas. O principal objetivo dos estudos hidrológicos é subsidiar projetos que envolvam recursos hídricos, com enfoque em seu uso, como no abastecimento d’água, geração de energia, irrigação, hidrovias, diluição de efluentes, esportes e turismo. Desta forma, para que o planejamento de uma rede tenha êxito em atender as múltiplas demandas ou, em acompanhar os diversos tipos de ocorrência em uma determinada bacia hidrográfica, é importante projetar o monitoramento hidrológico com base em todas as ações nela decorrentes, ou seja, com base tanto nas características fisiográficas da bacia em estudo quanto nas atividades desenvolvidas. Além disso, o monitoramento hidrológico deve produzir informações precisas e com operação de caráter contínuo. Sendo assim, o objetivo do presente estudo está em compilar as diretrizes preconizadas pela Agência Nacional de Águas, órgão responsável pela implementação da Política Nacional de Recursos Hídricos e do Sistema Nacional de Gerenciamento de Recursos Hídricos, e apresentar uma proposta para o planejamento da rede hidrológica da Bacia do Rio São João, localizada na mesoregião das Baixadas Litorâneas do Estado do Rio de Janeiro, com apoio de novas tecnologias, que dê um enfoque especial ao monitoramento do transporte de sedimentos- fundamental na tomada de decisão quanto às ações futuras de recuperação ambiental na bacia. Com o detalhamento destas informações, foi possível verificar a insuficiência do monitoramento na bacia e produzir um conjunto de recomendações que visa a priorizar a gestão dos recursos hídricos a partir de um efetivo monitoramento hidrológico.

This paper demonstrates that it is possible to implement a flood control system (called “piscinão”) in Niterói city, located in Rio de Janeiro State, Brazil composed by a reservoir that retains temporally the storm water. The recommended design storm equation and flood routing were applied in order to design the reservoir capacity. The results indicate that it is feasible to implement such solution, reducing more than two thirds of the peak discharge downstream, thus mitigating the damages caused by flood in Niterói city.
