GOALS AND CONDITIONS • Safety: stabilizing critical water levels despite increase of design discharge of 1000 m3/s • Increase of spatial quality: – Socio-economic value – Ecological value – Aesthetic/ cultural value – Sustainability • Implementation in partnership between national and regional authorities • Completion deadline: 2015 • Put 2015 plan in perspective of long-term vision (2050+) • Strictly limited budget16-18 Novemberbillion Euros 21-11-2011 Ljubljana of 2.2 2011 WWF6 ECRR Seminar 15

TOOLBOX OF MEASURES (green = best potential for ecological restoration) • Inside existing floodplain • Outside existing floodplain – Riverbed deepening – Detention areas – Groin improvement – Bypasses/ ‘green rivers’ – Creating side-channels – Widening of floodplain by – Removing obstacles replacement of dikes or – Strengthening of dikes (final depoldering option if no room available at reasonable costs) Selection of measures based on: cost-effectiveness, contribution to spatial quality and administrative/political feasability WWF6 ECRR Seminar 21-11-2011 16 Ljubljana 16-18 November 2011
