Method used |
Conform the Directive, GES and the environmental targets for the Belgian marine waters are defined on the basis of the eleven qualitative descriptors listed in Annex I of the Directive. The definition of GES is expressed in a qualitative description of what GES would look like when achieved for each of the descriptors. This is then underpinned by a set of more detailed quantitative environmental targets based on established environmental thresholds/limits for state, pressure or impact (Art. 10). Where quantitative environmental thresholds could not be set, trend-based or qualitative thresholds were used. The complete package of GES and environmental targets needs to give a complete and balanced overview. |

Description [Targets] |
An impact demands consideration if one of the following conditions – related to the bottom stress on a 14 days spring tide/neap tide cycle as computed by validated mathematical models – is met:
(i) there is an increase of more than 10% of the mean bottom shear stress
(ii) the variation of the ratio between the duration of the bottom shear stress and the duration of the erosion is outside the “- 5%, + 5%” range |
This at least implies that the changes in flow patterns resulting from concerned human activities are in such a way that erosion and sedimentation remain balanced. |
