Title : Assessing the Impacts of Extreme Weather Events on Infrastructures

Speaker : Brian Bush A Visiting Scientist with RAL

**Abstract:
Historically, weather-related events have created the greatest damage among incidents involving critical infrastructures (e.g., transportation, energy, telecommunications, public health networks), and many societal and economic impacts of extreme weather stem from their dependence on these facilities. Furthermore, infrastructure often mediates the impact of extreme weather upon society and the economy: it may either exacerbate or mitigate consequences. In this talk, we will highlight ongoing work to better estimate such impacts and consequences, focusing on hurricanes, ice storms, and increases in temperature due to climate change. These studies typically combine the output of numerical models of natural systems (weather, climate, storm surge, etc.) with engineering models of infrastructure and heuristic models for demographic and economic impacts. We will review the models and provide examples of their output and products.
