HAZUS-MH Flood Loss Estimation Methodology. II. Damage and Loss Assessment

TLDR

Part I of this two‑part paper reviewed the HAZUS‑MH Flood Model and its riverine and coastal flood‑characterization capabilities, including the Flood Information Tool for rapid analysis of stream discharge data and topographic mapping to determine flood frequencies across floodplains. The study reports the Flood Model’s damage and loss estimation capability, featuring a library of over 900 damage curves for various buildings and infrastructure. The model estimates shelter needs and direct/indirect economic losses from property damage, and supports analyses of flood warning, levee benefits, structural elevation, and flood‑mapping restudies.

Abstract

Part I of this two-part paper provided an overview of the HAZUS-MH Flood Model and a discussion of its capabilities for characterizing riverine and coastal flooding. Included was a discussion of the Flood Information Tool, which permits rapid analysis of a wide variety of stream discharge data and topographic mapping to determine flood-frequencies over entire floodplains. This paper reports on the damage and loss estimation capability of the Flood Model, which includes a library of more than 900 damage curves for use in estimating damage to various types of buildings and infrastructure. Based on estimated property damage, the model estimates shelter needs and direct and indirect economic losses arising from floods. Analyses for the effects of flood warning, the benefits of levees, structural elevation, and flood mapping restudies are also facilitated with the Flood Model.
