Technical and financial agreement between partners for comprehensive, joint and sustainable management on the scale of a coherent hydrographic unit (usually a river, lake, bay or aquifer). With the sub-basin management plan (SAGE), the
Sub-basin or group of sub-basins whose boundaries can be determined by the river basin management plan (SDAGE). This is the reference unit for delimiting the boundaries of the
Planning document for water management, established for each basin or group of basins, which sets out basic guidelines to achieve sound and sustainable water resources management, determines the objectives for water bodies and plans the necessary provisions to achieve the environmental objectives, to prevent the deterioration of water status and give fundamental orientations. The SDAGEs, approved for the first time in 1996 under the Water Act of 1992, have been updated in late 2009 to meet the requirements of the Water Framework Directive (WFD). They now include management plans under this Directive. The SDAGE is developed and adopted by the
A system for collecting data from several measuring stations having at least a targeting specific data (i.e. network for hydrometric measurements, piezometric measurement network) and which are carried out measurements or draw samples for later analysis. Each network meets common rules aimed at ensuring the consistency of observations, including the density and purpose of the measuring stations, the selection of compulsory parameters and the choice of measurement protocols, the determining of a periodicity to be complied with. All these rules are described in a protocol.
Postponement of the 2015 deadline to achieve "good status" of waters, in accordance with the Water Framework Directive 2000/60/EC. The greatest postponement, set at 2027, must be justified by at least one of the following reasons: technical feasibility, natural conditions, disproportionate costs, force majeure events (for temporary exemptions) or the development of projects responding to reasons of public interest.
Action to establish and/or manage a set of facilities on the river or in the river basin to reduce variations in the hydrological regime of a river (significant low-flow, flash flood, etc).
Document prepared for the basin or group of basins and for the duration of a six-year management cycle (2010-2015, 2016-2021, 2022-2027, etc), which identifies the key measures to be implemented for achieving the objectives defined in the river basin management plan (SDAGE), including the environmental objectives of the
Key point for water management usually defined downstream of reference hydrographic units for sub-basin management plans (SAGEs) and/or within those units whose boundaries can be determined by the river
