The Objectives of the The Objectives of the ActivityActivity

•for the continuity of time series, we need for the continuity of time series, we need to identify surface water (rivers, lakes) to identify surface water (rivers, lakes) and groundwater WISE-SoE monitoring and groundwater WISE-SoE monitoring stations which are identical with the stations which are identical with the monitoring stations reported under WFD monitoring stations reported under WFD Article 8 (stations matching)Article 8 (stations matching)

•specification of countries and water specification of countries and water categories for which the match is poorcategories for which the match is poor

Matching of Groundwater Matching of Groundwater BodiesBodies

•matching of EIONET groundwater bodies matching of EIONET groundwater bodies with WFD Article 5 groundwater bodies = with WFD Article 5 groundwater bodies = fully identical delineation of gw bodies in fully identical delineation of gw bodies in both casesboth cases

•WFD groundwater bodies should be used WFD groundwater bodies should be used from now onfrom now on
