All-Risk - Implementation of new risk standards in the Dutch flood protection program (STW-NWO Perspectief Program)
The introduction of new flood risk standards in the Netherlands leads to a complex task to assess all flood defences and to reinforce dike sections that do not meet these new standards. There are still many uncertainties (a.o. related to the impact of climate change), which results in a need for more knowledge and innovation. Furthermore, the involvement of a broad range of stakeholders forms a challenge.
All-Risk is expected to result in major savings in public expenditures, as future dike reinforcements can be more cost-effective than in the traditional, often conservative, approach.
All-Risk participants: Delft University of Technology (program leader), Wageningen University, NIOZ & RU Groningen, UNESCO-IHE Delft, University of Twente, Utrecht University, Radboud University Nijmegen. Users: Companies, Knowledge Institutes and International academic partners, Water boards, RWS, NGO’s, Provinces.
I am projectleaders of the subproject 'Shared use of flood defences'. (PhD Richard Marijnissen)
Large stretches of coastal and river dikes are used for multiple co-functions (including nature and landscape values). Some of these functions (e.g., recreation or agricultural use) imply a shared use of the flood defence, and hardly affect the functioning of the flood defence (under proper management and maintenance). This project addresses the question of how to enable multiple uses in the new flood risk approach, while at the same time meeting the reliability requirements. It will focuses on different representative cases (e.g. the Dutch Wadden Sea coast, and in particular on the innovative Parallel defence concept in Delfzijl and on the Wide green dike along the Dollard – eastern Wadden Sea). Attention will be paid to all different functions in the foreshore, the dike zone, as well as at the landward side of the dike zone.
