Jos TimmermanRIZA
Some figures:
• 1300 Waterbodies, 40 types, still under discussion
• Only very few natural waters• Most waters thought to be at risk in 2015• Lakes, rivers, transitional waters and
coast• Managed by 37 watermanagers (27+ 10)• Divided in 4 catchment areas : Rhine,
Meuse, Scheldt and Eems
Monitoring
• Guidelines ready for ecology and chemical substances
• Discussion on number of waterbodies to be monitored for ecology
• Most of the watermanagers are already monitoring chemicals
• In particular fish monitoring new to many watermanagers
• Minimum frequency has been chosen
Example: Points of discussion for Biological Monitoring
• Artificial en Heavily modified : what will be the objectives?
• How to aggregate waterbodies? • How to deal with protected area’s and
Groundwater bodies? Which objectives are leading?
• Cost efficiency, what is reasonable?• Quality of measurements and statistics
