Tool: Hazus-MH Flood Module


The software calculates flood damage to infrastructure and populations over a U.S. census tract, county, or state. The hazard is based on an input of a set of floods, or a scenario flood using depth-discharge frequency. A combination of hydraulic and hydrologic modelling is added to a digital elevation model (DEM). Hydrologic modelling is done via stream gauge data and a regression equation for discharge frequency for each reach. Hydraulic modelling is done in 2D, using cross sections, Manning’s n, and all flow regimes. The estimates are confined to within the floodplain. The relationship to inundation depth is generally used within the flood vulnerability module.
