1. Implementation of the WFD on coastal and transitional waters in France
Franck BRUCHON
Seine Normandy Water Agency

2. Definition of waterbodies
Creation of specific working group for C&T waters in july 2001
System B + bottom-up approach
Coastal waters : obligatory factors + wave exposure + substrate composition
Transitional waters: obligatory factors (in a first step)
Study of pertinence and data accessibility for each factor, at national scale

3. State of data availability

4. Salinity Definition Causes of variability Measurements Models
Amount of salts per kg of water (average 35 to 37 ‰)
Causes of variability
Marker of freshwater inputs (1 ‰ decrease  3% freshwater)
Evaporation in very confined zones (lagoons)
Measurements
RNO, REPHY databases….
Advantages : rapidly accessible data
Drawbacks: uncomplete coverage of the coast, poor description of variability
Models
Advantages : good coverage and description of variability
Drawbacks: validation to be conducted

5. Salinity (spatial variability)
Atlantic coast
Bay of Lannion
Effects of large estuaries (Loire, Gironde, Adour)
Local effects (Douron, Leguer, Yar…..)

6. Salinity (temporal variability)
Measurements
north of Oléron island
Model results

7. Definition of waterbodies
Factors:
latitude x longitude x salinity (mean; std. dev.) x tidal range (incl. use of numerical models)
mixing characteristics x transport conditions (residual tidal and wind-induced currents) x interaction with the bottom (wave exposure, maxi current velocity, susbstrate composition )
Method testing on Seine Normandy coast (Channel) and Mediterranean sea
Methodological improvement/adjustments
Application to all French transitional and coastal waters
Results expected in spring 2002
Preliminary approaches:
LB: 18 sectors ; 88 zones
SN: 8 sectors ; 21 zones
RMC : 50 zones
estimated Total for all France : zones
Grouping of certain zones considered to avoid reaching a too large amount of zones
Taking into consideration pressures of human activities on the defined zones -sub-dividing or regrouping defined zones

8. Artificial and Heavily modified waters
A methodological document
A test-application on Seine Normandy coast (simultaneously to the waterbodies definition test)

9. Protected areas
List and cartography of all protected areas, considering the different types and levels of protection
RAMSAR, SPZ, Natural reserves, national parks….
Human activities areas: bathing, shellfarming…
Method testing on 2 coasts : outh brittany and east Mediterranea
Method improvement for national application
