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.

The construction and operation of cascade reservoirs has changed the natural hydrological cycle in the Yalong River Basin, and reduced the accuracy of hydrological forecasting. The impact of cascade reservoir operation on the runoff of the Yalong River Basin is assessed, providing a theoretical reference for the construction and joint operation of reservoirs. In this paper, eight scenarios were set up, by changing the reservoir capacity, operating location, and relative location in the case of two reservoirs. The aim of this study is to explore the impact of the capacity and location of a single reservoir on runoff processes, and the effect of the relative location in the case of joint operation of reservoirs. The results show that: (1) the reservoir has a delay and reduction effect on the flood during the flood season, and has a replenishment effect on the runoff during the dry season; (2) the impact of the reservoir on runoff processes and changes in runoff distribution during the year increases with the reservoir capacity; (3) the mitigation of flooding is more obvious at the river basin outlet control station when the reservoir is further downstream; (4) an arrangement with the smaller reservoir located upstream and the larger reservoir located downstream can maximize the benefits of the reservoirs in flood control.

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.

The core technique of flood forecast and pre-warning of a river basin is the numerical simulation of flood process in a complicated flood control system. According to the structural features, flood features, and flood process mechanism of a large and complicated flood control system, a 1D and 2D coupled numerical simulation model was established. The 1D model was used for the trunk river and main branches, and the 2D model was used for flood districts. The coupled 1D and 2D was used to simulate the flood regulation and process in rivers, lakes, flood districts, and floodways. A case study was conducted in the section from the Wangjiaba to Bengbu floodgates in the middle reach of the Huaihe River. The coupled model was employed to synchronously simulate the branch rivers and trunk flood of the river basin and to improve the accuracy of flood simulation, flood forecast, and regulation of the river basin. The parameters of the model for simulating the flood process of the Huaihe River Basin in 2003 were calculated and verified, and the flood process in 2007 was demonstrated. The simulated results show that the flood regulation and process can be accurately simulated by the proposed numerical model, and the accuracy requirements can be satisfied. Finally, the model was applied to the effect analysis of a four-grade emergency flood control plan in the Huaihe River Basin.
