Modeling Fundamentals: Evaluating U.S. Flood Model Loss Output with Historical Loss Experience

Recently, AIR released a major update to our flagship U.S. hurricane model, along with a substantially updated U.S. inland flood model. Both models incorporate the same new pluvial component that uses a physically based 2-dimensional (2D) shallow water wave model to simulate pluvial flood risk over the entire contiguous U.S. These two models also incorporate the same new precipitation-induced flood vulnerability framework. Together, these two models provide a comprehensive view of U.S. flood risk—from both tropical and non-tropical sources on and off the floodplain as well as from storm surge.

Modeling Fundamentals: Why Does Verisk Conduct Post-Event Damage Surveys?

This article focuses primarily on damage surveys conducted in the aftermath of U.S. hurricanes and addresses how and why we conduct them. As we update our U.S. hurricane model—a tool that helps quantify the risk—we uncover more questions that are typically answered only after studying another event.
