Reducing negative side effects of floods: case Paris
Published: 20 February 2018
The Deltares CIrcle tool, a touch table application used for discussing cascading effects with network owners and stakeholders, was used by French researchers. This was done in collaboration with governmental authorities to gain more knowledge on the cascading effects and dependencies between different stakeholders in case of a flood. The tool was used in two workshops (Ateliers Collaboratifs) for the EURIDICE project. In the workshops previous flood events in Paris were discussed with the aim of learning from these events with regards to the possible cascading effects between critical infrastructure networks.
New information on how to coordinate
CIrcle was applied by the French researchers Valérie November (CNRS) and Servane Gueben-Venière (LATTS). They used the approach to collaboratively design a critical infrastructure model with different Parisian stakeholders and to connect the model to river discharge forecasting in the Seine. The shared knowledge of the participants to the workshop brought into light new information on how different stakeholders may better coordinate with each other in case of a flood.
Servane Gueben-Venière (researcher LATTS): “One of the great advantages of CIrcle is that you can unfold the chain of domino effects: CIrcle makes it possible to circulate information between the actors dependent on each other and to capitalize the knowledge or information discussed during the workshops”
The next step for the French researchers is to visualise the collected knowledge and data along the Seine. For Deltares the next step is to make the CIrcle tool available online. The experience with the EURIDICE project has shown that other researchers can use the CIrcle tool themselves and design their own workshops around it. The launch of the online version of CIrcle is planned in May 2018.
