This report summarizes the main concepts and methodologies that are used to assess flood risk for road networks. The report presents references and examples, and is intended to be a starting point for practitioners in the field.
Flooding poses an important threat to roads, and can lead to massive obstruction of traffic and damage to road structures, with possible long-term effects. Because of the time and costs required for rebuilding, sustainable and long-term planning is crucial; therefore, the consideration of flood risk constitutes an important input for decision making in planning this type of infrastructure. Flood risk analysis for road networks allows plans to be carried out in an appropriate manner, allocating resources for prevention, mitigation, and restoration.
