1. Assessment of the Effectiveness of PoMs

2. Policy questions
Are we identifying all relevant pressures and in a homogeneous and consistent way across the EU?
Are we addressing them appropriately in the PoMs?
By fully implementing a given PoM, are we really achieving the WFD goals?
What is the risk of failure?
Which preventive/corrective actions should be taken?
The JRC is applying its Integrated Water Modelling Platform (IWMP) to help answering these questions.

5. EC and MS agree that problems are under control
Class 1 MS and EC aware of the problem MS plans measures JRC IWMP to simulate the effect of planned measures and to suggest additional measures.
Class 2
“Green light” areas:
EC and MS agree that problems are under control
No need for further assessment
Class 3
Problem NOT identified by the EC at European level
JRC IWMP should be improved (lack of data? Lack of model detail?)
Or:
The MS feels the problem is “relatively high”, but EC considers it “relatively low”.
MS plans measures.
JRC IWMP “learns from errors”
Class 4
Typical case for priority in-depth assessment
Confirm the conclusions of MS?
Confirm the conclusions of the EC?
a new representation of the situation shared btw EC and MS?
Recommendations on additional measures to take in the PoM

7. In-depth assessment Thorough reading of the RBMP and PoM
Quantification of pressures
Point and diffuse pollution
Hydromorph. pressures
Water abstractions
Saltwater intrusion
Other?
Quantification of the modification of pressures due to planned measures
Simulation of the status achieved through implementation of measures
Identification of possible unachieved goals
Quantification of additional requirements to achieve goals

11. Way forward EU-scale screening exercise
Mapping Class 1 : Class 4 for all RBDs for all pressures
Based on expert (semi-quantitative) joint interpretation of JRC IWMP assessment and pressures reported by MSs as limiting achievement of 2015 goals
Pilot in-depth assessments
transboundary RBDs of highest interest
Priority to Danube (and Sava), Guadiana+Tagus+Douro/Duero
To be extended ideally to all “Class 1” and “Class 4” RBDs
Classification referred to each pressure type for SW and GW
For each catchment where a pressure is classified of “class 4”, a specific assessment of that pressure may be necessary (integrate MS data with EC data).
