This study provides the first global evaluation of both direct and indirect flood hazard impacts on road transportation networks. It constructs topological road networks for 2,564 human settlements, representing over 14 million kilometers of urban roads. It assesses their exposure to pluvial and fluvial flood risks under 10 scenarios, corresponding to different flood intensities (1:5 year to 1:1,000 year return periods). Under each scenario, the study analyzes direct infrastructure exposure and assesses the indirect effects of flood-induced mobility disruptions: route failures, travel delays, and travel distance increases. The results document a positive relationship between flood return period and flood impact (both direct and indirect). Compared with direct flood hazard exposure, the indirect impact of floods on mobility is more prominent and heterogeneous. The average share of the road network that is flooded by at least 0.3 meters is 3.64 percent (or 24.84 percent) under the 5-year (or 1,000-year) return period, yet 11.58 percent (or 65.67 percent) of the simulated trips fail in the same scenario. The results enable comparisons of exposure and vulnerability of road networks to flood hazards across countries, allowing the identification and prioritization of urban transport resilience measures.

Climate Change and Flood Risk Management discusses and problematises the integration of adaptation to climate change in flood risk management. The book explores adaptation to climate change in relation to flood risk events in advanced industrial states. It provides examples of how flood risk management, disaster and emergency management, and adaptation to climate change may intersect in a number of European and Canadian cases. Taken together, the studies show that integration of adaptation in flood risk and emergency management may differ strongly - not only with risk, but with a number of institutional and contextual factors, including capacities and priorities in the specific municipal cases and within a national and wider context. The book will be relevant to researchers involved with adaptation to climate change and those involved with comprehensive planning in relation to it. It will also be of interest to academics within the fields of environmental studies and the environmentally-oriented social sciences.

This study examines flood risk prevention of the Seine in the Ile-de-France region. It highlights the impacts a major flood, like the one in 1910, could have on the well-being of citizens, city management and the economy.
