1 Integrated River Engineering Project Danube East of Vienna

2 Integrated River Engineering Project on the Danube East of Vienna is a project of via donau, realized ed on behalf of the Austrian Ministry of Transport, Innovation and Technology. is a priority project of the European Commission (Trans-European Transport Network, PP18). With this project via donau is fulfilling the statutory mandate to provide for better environmental and navigational conditions. Project area: river-km 1.921, ,7 from the Freudenau Power Plant to the Austrian-Slowak border via donau I 2

3 Deficits in the project area Riverbed Heavily regulated river Inadequate degradation in National Park area fairway depths decoupling of river habitats of typical limited competitiveness and floodplains, falling local flora and fauna of inland water- groundwater levels are at risk way transport via donau I 3

13 Pilot Project Bad Deutsch Altenburg Status: Premonitoring: since 2005 Construction works: since February 2012 approx. mid 2014 September 2012: preparing areas for construction by searching for explosive ordnance and forest clearance reconstruction of groynes The construction works are accompanied by: a technical and ecological on-site supervision an integrative Monitoring-Team the Christian Doppler Research Lab IM Fluss for more complex and scientific monitoring the Stakeholder Forum via donau I 13

14 Overall Status Establishment of an interdisciplinary steering committee: 2002 Examination of alternative and variant solutions: Moderation procedure to ensure public participation: Model testing: Pilot Projects east of Vienna finalized: Environmental Impact Assessment for Global Project: since 2006 Christian Doppler Research Laboratory: established in May 2010 to improve scientific monitoring and to optimize project costs Stakeholder Forum: established in January 2012 Pilot Project Bad Deutsch-Altenburg: construction period from February 2012 to approx. mid Further measures east of Vienna will use the experience gained from the pilot projects and tests. via donau I 14

16 Integrated River Engineering Project & Joint Statement The measures east of Vienna Are the result of an integrative planning approach (official starting point: installation of an interdisciplinary steering committee by the bmvit in 2002) therefore comply with the objective of the Joint Statement t t present a living and successful example for integrative planning for combining the needs of navigation and ecology Are honoured as best practice for integrated planning approaches in the Joint Statement The process for achieving the Joint Statement was supported by the bmvit, via donau and the Danube Floodplain Nationalpark by sending experts hosting the first workshop in April 2007 via donau I 16

17 Integrative Planning Joint Statement on Guiding Principles for the Development of Inland Navigation and Environmental Protection in the Danube River Basin (2007) initiative by the ICPDR, cooperation with Danube Navigation Commission and International Sava Commission the integrated planning approach was honored as best practice within the joint statement Manual on Good Practices in Sustainable Waterway Planning (2010) initiative by the EU PLATINA Project the integrative planning approach served as a showcase for the planning philosophyp measures are described as good practices for ecologically orientated river engineering via donau I 17

18 Stakeholder Forum The Stakeholder Forum ( Akteursforum ) allows the structured integration of stakeholders in the project. The forum will accompany the realization of the Pilot Project Bad Deutsch-Altenburg discuss the outcome and the consequences for future projects, especially the consequences for the Integrated River Engineering Project Ten stakeholders with voting power: 4 stakeholders from economy / navigation sector 4 stakeholders from environmental NGOs 1 representative of National Park 1 representative of ICPDR Observers are welcome to the meetings The stakeholders are supported by an independent Scientific Board. It is made of 5 experts for the fields of navigation, ecological river engineering, hydrology and ground water, biodiversity, hydrobiology and fish ecology via donau I 18
