Quality element
Définition
Sens technique
Partial view of the water status, which gives rise to control operations, the results of which are used by an assessment to determine quality indicators. The quality element is described by a parameter or set of parameters (parameter group). The list of quality elements is defined in Annex 5 of the

Investigative monitoring
Définition
Sens technique
Control, as part of the water status monitoring programme, designed to look for the pressure which causes an observed degradation. It is carried out when the reasons for any significant alteration of the environment are unknown, to determine the causes for a water body not meeting the environmental objectives (when operational control has not yet been established), or for monitoring
