what, when, who Ralph Schielen Rijkswaterstaat - University of Twente 1 MOTIVATION Now, much is happening at a large scale in rivers and streams…       Meuseworks (Maaswerken) Room for the River (Ruimte voor de Rivier) EU Flood Directive EU Kaderrichtlijn water Natura2000 Deltaprogram 2 PROJECTS ROOM FOR THE RIVER 3 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 4 EXAMPLES OF MEASURES Project A: replace groins with longitudinal dams 5 EXAMPLES OF MEASURES Project B: Free erodible banks Now Future? 6 EXAMPLES OF MEASURES Project B: Side-channels Vreugdenrijkerwaard 7 EXAMPLES OF MEASURES Project D: deepening of summer bed / suppletion 8 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? 9 RESEARCH DOMAINS Hydraulics Management / Governance Communication Ecosystem Services Ecology Morphology Application 10 PROJECTS 15 PhD and 5 postdoc positions 11 CONSORTIUM RIVERCARE Universities: Partners: 12 CONSORTIUM RIVERCARE 13 (SUB-)PROJECTS A Optimizing longitudinal training dam A1 Hydraulics of LTDs (PhD) design A2 Ecology of LTDs (PhD: Frank Collas) B Side channels and erosion of natural banks B1 Side channels (PhD) B2 Natural banks (PhD) C Regional River Systems C1 Morphodynamics (PhD) C2 Hydrology (PhD: Tjitske Geertsema) D.
