Hurricane Wind versus Storm Surge Damage in the Context of a Risk Prediction Model
Publication: Journal of Structural Engineering
Volume 143, Issue 9
Abstract
Annualized hurricane-related losses in the United States are in the billions of dollars. The majority of the coastal population lives in buildings prone to hurricanes, which could result in wind damage (due to high wind and/or wind-driven rain infiltration) and water damage (due to storm surge and waves or freshwater flooding), which are typically insured by separate entities. In the event that a structure is subjected to damage from both wind and water hazards, the proper allocation of damage for insurance purposes is challenging because wind and water vulnerability are often assessed with separate models. The challenge is how to combine the results of these different models and properly assign damage causation. This paper proposes a methodology for the assessment of multihazard vulnerability for implementation in the Florida Public Hurricane Loss Model, in which the damage from each hazard (wind and rain, storm surge, and freshwater inundation) is calculated separately. An engineering approach in conjunction with hazard information (intensity, timing) and statistical methods is utilized to allocate damage.
