MOTIVATION
Now, much is happening at a large scale in rivers and
streams…

AMBITION
… this offers a unique opportunity to:
 Monitor effects (link up with monitoring programmes)
 Better understand the response of the river system
 Develop knowledge and tools for:
- sustainable river management
- cost-effective maintenance
 NL proeftuin (Dutch show case)
 Strengthen international competitive position and enhance export
opportunities

Questions of users and scientists
 Long-term effects? (hydraulic, morfologic, ecologic)
 Uncertainty in forecastes developments?
 Finetune userfunctions: optimalising ecosystemservices?
 Governance: how to design decision processes in river management?
 Effective communication scientific knowledge to users?
 Enlarging exportpossibilities of Dutch knowledge in rivermanagement?
