Resiliants: WATER aims to create a predictive dashboard for avocado...
We developed both methods and workshop set-ups for stakeholder engagement, and the technical tools that can support these engagement efforts. In our view, these two are intrinsically linked, since the context in which the technical tools will be used largely determine the design and development of these tools.
1) Our innovation aims at supporting decision-makers and stakeholders in decisions on spatial planning. In many densely, urban areas around the world, we see that climate adaptation needs to compete with other claims on the available space, like housing. Developing accessible methods to involve stakeholders in flood risk management contributes to the inclusion of climate adaptation in spatial developments.
2) We generally observe a discrepancy in the pace at which urban designers and architects, on one hand, and engineers, on the other, modify their designs. Urban designers and architects adjust their designs on a daily basis, whereas engineers often create a design only once or twice throughout the entire design process. By using interactive modelling in the 3Di LiveSite, this difference in design adjustment speed can be reduced.
3) The 3Di LiveSite is designed to make the use of hydrodynamic models accessible and comprehensible for a wider audience beyond hydrology experts, thereby bridging the gap between specialists and non-specialists.

The 3Di LiveSite can be an essential tool to provide people with a better understanding of the factors contributing to floods and the measures that can be taken to mitigate their negative consequences. By offering an easy-to-understand interface, people can engage with the models independently, enabling a broader audience (beyond the “usual suspects”) to be involved in addressing flood risk issues.
By involving inhabitants in interactive flood modelling sessions and engagement sessions in which inhabitants are actively involved in the analysis of areas vulnerable to flooding beforehand, they will become more susceptible to information provided by governmental organizations during extreme flooding events. Furthermore, during these interactive sessions, the municipality can test in which way information is most easily understood by residents. Especially in crisis situations, this is very important, as the information needs to be very quick and easy to comprehend to be effective. Stakeholders from businesses and investors can also be involved in joint working sessions and granted access to the 3Di LiveSite. By engaging them in conducting flood calculations and studying the effect of different measures using the models in the LiveSite, they gain more insight into climate and flood risks. Furthermore, businesses and investors will gain a better understanding of the benefits of flood protection measures and provide them with the data to make their own financial cos-benefit analyses. This will motivate them to adopt more community-oriented perspectives with a high valuation of co-benefits.
The assessment of the estimated costs of flood events by industry starts with the calculation of possible flood scenarios. These calculations can be carried out with models in the 3Di LiveSite. Subsequently, the results of these calculations (i.e. the flood maps) can be used in combination with damage estimation models to obtain the estimated costs of flooding.
Over the years, as Nelen & Schuurmans, we have developed different methods to apply interactive modelling for engaging both specialists and non-specialist stakeholders in the design process of flood risk reduction strategies in various projects. There has always been a strong connection between refining these methods and workshops setups on one hand, and the design and further development of our technical tools on the other. We have already applied our method in various projects in the Netherlands. We would no like to do the same in the Danish market, further developing and formalizing the method. The primary technology underlying these methods is the 3Di technology, particularly the 3Di LiveSite. This technology has been continuously developed over the last 10 years by Nelen & Schuurmans, and is initially based on mathematical concepts that were studied at the TU Delft (see https://3diwatermanagement.com/learn/publications/ for different scientific articles). During the early stages of 3Di development, the technological development was a joint project of Nelen & Schuurmans and Deltares (a Dutch research institute in the water sector). However, after the first 4 years of collaboration, Nelen & Schuurmans continued independently with the development of 3Di. Over time, the functionalities of 3Di have been consistently expanded.
Like any model, the quality of the results from the model simulations in the 3Di LiveSite relies on the quality of the input data. The primary input data for the hydrodynamic model includes a high-accuracy Digital Elevation Map (DEM) and the boundary conditions that are used to force the model. From previous projects in Denmark, we have experienced that Denmark is a data-rich country with an accurate DEM available at a resolution of 40 cm. Since this innovation will be implemented in the urban area of Esbjerg, it is important to include the city’s sewerage system in the model. We will need to cooperate with the municipality of Esbjerg to obtain data. When the accuracy of the input data is less, this will directly influence the uncertainty in the results. However, even with less accurate input data, it can still be useful to develop a hydrodynamic model and use its simulation results, provided that the user is aware that its results entail greater uncertainty. We will always clearly communicate the uncertainties to the end-users.

The main components of the system have been tested separately, and an initial integration exercise has been conducted.
