Stolberg, NRW, Germany - Vicht

The ProMaIDeS approach, offers a way of modelling these networks. This approach initially aims to determine critical infrastructure facilities that fail due toa selected flood event. It then quantifies how many people are supplied by the respective facilities. In the course of modelling the CI network, redundancies in the supply networks and pre-planned emergency measures can be taken into account. Analysing the information can in turn reveal measures to strengthen the resilience of the region. In this thesis, the approach is applied in the catchment area of the Vicht near Stolberg (NRW) based on the July 2021 flood. The approach initially includes data collection on the CI in a river catchment area, such as Locations, water level limits, operating limits of CI facilities, the networking and dependencies of the various facilities, the repair time required after a failure and any protective measures. Based on this, a digital model of the critical infrastructure network in the Vicht catchment area is created and combined with a flood simulation. The superimposition of the digital model and the simulated flooding areas and water levels is then used to calculate which facilities are affected and how their failure will affect the population. By knowing the failures, appropriate measures can be planned to prevent them. CI can thus be better integrated into flood risk management.
