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 Ruhr, with an average flow of 80.5 m3/s at its mouth, is a comparatively small tributary to the Rhine River that has to perform an important task: to secure the water supply of more than 5 million people and of the industry in the densely populated region north of the river. The complex water management system and network applied by the Ruhrverband in the natural Ruhr River Basin has been developed step by step, over decades since 1913. And from the beginning, its major goal has been to achieve optimal conditions for the people living in the region. For this purpose, a functional water supply and wastewater disposal infrastructure has been built up. The development of these structures required and still requires multi-dimensional planning and performance. Since the river serves as receiving water and at the same time as a source of drinking water, the above-standard efforts of Ruhrverband for cleaner water also help to conserve nature and wildlife. Ruhrverband has summed up its environmental awareness in the slogan: “For the people and for the environment”. This basic water philosophy, successfully applied to the Ruhr for more than 80 years, will be continued in accordance with the new European Water Framework Directive, enacted in 2000, which demands integrated water resources management in natural river basins, by including the good ecological status of surface waterbodies as an additional goal.
