“Local impacts on road networks and access to critical locations during extreme floods” in Scientific Reports (2022).

An open-access article published in Scientific Reports 12: 1552 by Loreti et al. (2022) entitled “Local impacts on road networks and access to critical locations during extreme floods” has shown that recent approaches for understanding the resilience of transportation networks when facing floods mostly use the framework of percolation but they show on a realistic high-resolution flood simulation that it is inadequate. Indeed, the giant connected component is not relevant and instead, they propose to partition the road network in terms of accessibility of local towns and define new measures that characterize the impact of the flooding event. Their analysis allows to identify cities that will be pivotal during the flooding by providing to a large number of individuals critical services such as hospitalization services, food supply, etc. This approach is particularly relevant for practical risk management and will help decision makers for allocating resources in space and time.
