7.6. Definition of significant pressures and impacts

A key part of the characterisation of surface water bodies is the assessment of the risk that a surface water body may fail (in 2015) the objectives of the WFD unless appropriate measures are taken. The results of the risk assessment inform the monitoring of surface water bodies and the subsequent classification of status. It is crucial that methodologies used in risk assessment are fit for purpose in the sense of being able to identify and quantify all significant pressures within the RBD and their potential impact on status of surface water bodies (CIS Guidance Document No. 3). If not, (expensive) measures may be incorrectly targeted and objectives may (unexpectedly) not be met.

1. Please include here any comments which apply to all the schema elements in this Class.
2. In addition to those general schema element level comments, we welcome your views on: a) whether you think this Class can be simplified;  and b) whether you think the linkages with other reporting Classes or Schemas can be improved, and how;

swPressuresNotAssessed - Required.(SignificantPressureType_Enum)

Select the pressure types from the enumeration list that have not been assessed (i.e. pressure types that have not been considered because they were not deemed to be important in the RBD, no information was available, or any other reason). If all pressures have been assessed report ‘Not applicable’. The option ‘No significant pressure’ is not valid.

swSignificantPressurePointSourceTools - Required.(SignificantPressureTools_Enum)

Report the tools that have been used to define significant pressures from point sources. ‘Numerical tools’ includes modelling tools.

swSignificantPressureDiffuseSourceTools - Required.(SignificantPressureTools_Enum)

Report the tools that have been used to define significant pressures from diffuse sources. ‘Numerical tools’ includes modelling tools.

swSignificantPressureWaterAbstractionTools - Required.(SignificantPressureTools_Enum)

Report the tools that have been used to define significant pressures from water abstractions. ‘Numerical tools’ includes modelling tools.

swSignificantPressureWaterFlowTools - Required.(SignificantPressureTools_Enum)

Report the tools that have been used to define significant pressures from water flow regulation and morphological alterations. ‘Numerical tools’ includes modelling tools.

swSignificantPressureOtherSourceTools - Required.(SignificantPressureTools_Enum)

Report the tools that have been used to define significant pressures from other sources. ‘Numerical tools’ includes modelling tools. 

swSignificanceDefinition - Required.(YesNoCode_Enum)

Indicate whether significance been defined in terms of thresholds. 

swSignificanceLinkFailure - Required.(YesNoCode_Enum)

Indicate whether the definition of significance is linked to the potential failure of objectives. 

swPressuresReference - Required.(ReferenceType)

Provide references or hyperlinks to the relevant document and section where any other relevant information relating to pressure types can be found. Guidance on what should be included in this document is provided in Section 7.6.3.3.
