Flood Forecasting for Transportation Resilience: A Guide
Synthetic audio, Automated braille
Summary
Transportation systems are exposed to a diverse range of hazards, with flooding being one of the most common and consequential. State departments of transportation (DOTs) may use flood forecasts to inform actions such as issuing internal flood-level notifications, directing field… staff to flood locations, and issuing road closures. A flood-forecasting capability can help inform a proactive approach to managing flood impacts by supporting preparation for events, fast response times, and efficient use of resources. NCHRP Research Report 1131: Flood Forecasting for Transportation Resilience: A Guide, from TRB's National Cooperative Highway Research Program, seeks to empower state DOTs with technical resources and organizational insights to better predict the timing and magnitude of flooding and enable advanced early warnings to help protect critical infrastructure and enhance roadway safety.
