Article 5 report

Sens technique

According to the Water Framework Directive (WFD), it means analyzing the whole basin or group of basins, focusing on three aspects: characteristics of the basin or group of basins, impacts of human activities on water status and economic analysis of water use. The assessment especially aims to prepare later the master plan for water development and management * (SDAGE) and the programme of measures by assessing the risk of not achieving the environmental objectives for water bodies. The first assessments were adopted by the basin committees and approved by the basin coordinator prefects in…

Ecosystem

Sens commun

All living beings (Living communities), non-living elements and climatic and geological conditions (biotope) that are related and interact with each other, and which constitute a basic functional unit in ecology. The ecosystem of an aquatic environment is generally described by: the living beings that are part of it, the nature of the bed and river banks, the characteristics of the catchment area, the hydraulic regime, and the physical-chemical characteristics of water.

Warning level (or threshold) flow

Sens technique

"Threshold" value of the flow that triggers the first restrictions for some activities. These measures are taken at the initiative of the prefectural authority in connection with a crisis cell and in accordance with a crisis plan.

Sens technique

Directive 2000/60/EC of the European Parliament and of the Council of 23 October 2000 establishing a framework for Community action in the field of water policy, commonly known as the Water Framework Directive (WFD). It sets out environmental objectives and deadlines to improve the ecological and chemical status of surface water bodies as well as the quantitative status and chemical status of groundwater bodies. Some water bodies created by human activity or having their characteristics fundamentally modified by human activity, may be designated respectively as artificial water bodies (AWB) or heavily modified water bodies (HMWB). In this case, their characteristics and ecological functioning are described by an ecological potential. The WFD especially sets the general goal to achieve "
