Modeling Fundamentals: Defining Events in the Verisk U.S. Inland Flood Model

How Verisk defines U.S. inland flood events — helping insurers assess flood risk, apply hours clauses, and manage events with confidence.

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.
