Types, Pressures and Quality Elements - Rivers 4th Intercalibration Workshop March 17-18, 2003
River Intercalibration Regions Separation in Nordic, Alpine, Central, Mediterranean regions No need for a separate Atlantic ecoregion (as proposed for lakes) For selected types, include (Northern) UK and Ireland in Nordic region, and Spain (and Portugal?) in the Central region 4th Intercalibration Workshop March 17-18, 2003
River Intercalibration Types Core types proposed in the drafting group report too general to be used in the intercalibration Different sets of types were defined for the geographical IC regions, based on the core types 4th Intercalibration Workshop March 17-18, 2003

4th Intercalibration Workshop March 17-18, 2003 River IC Pressures Effects of the pressures organic pollution and nutrients similar -- merged Separation in pressures from urban and agricultural sourcess. This results in 4 pressures for the intercalibration: organic matter and nutrients (urban) organic matter and nutrients (agricultural) stream modification acidification Specified for the different IC types; for some types it is not possible to view the pressures separately. 4th Intercalibration Workshop March 17-18, 2003
