The design, construction and maintenance of Critical Infrastructures (CI) is commonly based
on standards that are rigorous, so as to withstand any climate or weather-linked pressures.
However, due to climate change, climate characteristics may shift, resulting in increased
frequency/magnitude of potential failures, or exposure to new unknown risks. As vital
components for the normal functioning of modern societies, the resilience of CIs under climate
stressors encompasses their structural integrity, their operational elements, and their capacity
to maximize business output. In this work, we propose an integrated and participatory
methodological approach to enhance the resilience of interconnected CIs to urban flooding
under climate change, by assessing the risk and introducing adaptation measures.
The main objectives of the proposed methodology and approach are: (i) to provide scientific
evidence for better understanding of how future climate regimes might affect normal operation
of interconnected CI in urban areas during their lifespan; (ii) to assess the cost-effectiveness
of different adaptation measures; (iii) to involve local stakeholders and operators in the co-design of the approach, as well as the assessment and the evaluation of adaptation measures;
(iv) to combine computational modelling with advanced 3D visualisation techniques for
effectively engaging stakeholders in decision making; (v) to include risk assessment and
damage functions co-designed by end-users and local stakeholders; (vi) to integrate all of the
aforementioned components in a specifically designed cloud platform as a Decision Support
System for end-users, (vii) to validate the DSS by the end users and local stakeholders.
The paper presents the computational background and tools. Additionally, it describes a Case
Study in Torbay, UK, where the full methodology and the proposed participatory approach
have been applied, with all the specifics, i.e., the scenarios of extreme flooding, the numerical
and visualization results, the response of the stakeholders and the evaluation of selected
adaptation measures.
