This page provides information on Hazus-MH's Flood Model, including new release features and success stories. This page is intended for Hazus users and other parties interested in using Hazus, specifically the Flood Model for flood mitigation and planning efforts.
Features of the Hazus-MH Flood Model
The Hazus-MH Flood Model allows planners and other practitioners to carry out a wide range of flood hazard analyses, including:
- Studies of specific return intervals of floods (e.g., 100-year return interval).
- Studies of discharge frequencies, including analysis of discharges from specific streams and the exposure to buildings and population from the resultant flooding.
- Studies of annualized losses from flooding.
- Quick Look assessments, which allows the user to quickly evaluate potential flooding from specific flood depths at specific locations.
- What if scenarios, which allow users to evaluate the consequences of specific actions, such as the introduction of flow regulation devices, acquisition of flood-prone properties and other mitigation measures.
The flood loss estimation methodology consists of two modules that carry out basic analytical processes: flood hazard analysis and flood loss estimation analysis. The flood hazard analysis module uses characteristics, such as frequency, discharge and ground elevation to estimate flood depth, flood elevation and flow velocity. The flood loss estimation module calculates physical damage and economic loss from the results of the hazard analysis.
Hazus-MH Flood Model Applications
The Flood Model has been widely used by state and local officials for risk assessment and mitigation planning, including:
- Savannah, Georgia Flood Loss Estimates and CRS Flood Mitigation Planning (2009)
- Using Hazus to Speed Disaster Recovery From 2008 Iowa Floods (2009)
- Pennsylvania Statewide Flood Hazard Study (2007), which includes damage estimates for 10-, 50-, 100-, 200- and 500-year flood events.
- State of Maryland Flood Hazard Study (2006), which includes a vulnerability assessment of the state's built environment to riverine and coastal flooding.
- Use of Hazus-MH in the Risk Assessment of 29 Counties in Indiana (2006)
