Phythobenthos (Diatoms) are a sub-element of the biological quality element (BQE) of the aquatic flora used for the assessment of the ecological status/potential. The assessment is made in 5 classes : high (blue) - good (green) - moderate (yellow) - poor (orange) - bad (red). The diatom assemblages are different in function of concentrations of nutrients and organic pollutants.

The WFD's (2000/60/CE) quantitative status objectives aim to ensure a balance between groundwater withdrawal and recharge.

This map shows the extent and inundation depth of surface runoff in a 100-year heavy rainfall scenario [D60T100].

The hydromorphological status was determined by a monitoring compliant with the Water Framework Directive (Directive 2000/60/EU). The elaboration of a structural quality mapping is one part of this monitoring. Within the scope of the work on the structural quality mapping, a total of 31 parameters in the area of the river bed, the river bank and the floodplain are assessed so that the structural quality mapping contains detailed information on the river morphology and the river continuity. In this case, the evaluation of the mapped sections is based on five classes. The areas river bed, left river bank, right riverbank, left floodplain and right floodplain are represented in 5 strips.

The percentage of analysis in which the parameter polycyclic aromatic hydrocarbons meets the threshold value

In this case, the evaluation of the mapped sections is based on seven classes. The areas river bed, left river bank, right riverbank, left floodplain and right floodplain are represented in 5 strips.

The percentage of analysis in which the parameter trihalomethanes sum meets the threshold value

The percentage of analysis in which the physico-chemical parameters meet the threshold value

Monitoring stations for groundwater quality and quantity of the 4th cycle (2021-2026) regarding the water framework directive (2000/60/CE).
