ABSTRACT. - Modern concepts of integrated management and sustainable development of water resources that are provided in the European Directives on water and in the Romanian legislation, combines aspects of rational use of water resources with the protection of aquatic ecosystems. The main objectives of these concepts, are part of the ecological reconstruction and rivers to:
§ optimization (improvement) and ensure appropriate habitat biodiversity conservation;
§ ensuring appropriate flow rates of water for protection of aquatic ecosystems;
§ providing longitudinal and lateral connectivity of the flow rates water circulation to ensure optimal upstream and downstream-upstream-downstream fisheries fund.
A very important step in the complex process of environmental reconstruction, is to ensure the flow of environmental protection along water courses (flow protection of aquatic ecosystems) and the minimum flow required in any section of a watercourse river, to ensure natural conditions of life of existing ecosystems and future. In this context, the paper aims to present some of hydromorphological requirements, including compliance protection flow of aquatic ecosystems, the water courses must meet in order to achieve established by the Framework Directive 60/2000/CEE the good ecological status of water bodies.
Keywords: protection flow of aquatic ecosystems, hydromorphogic indicators, ecological reconstruction, good ecological status
