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 allows 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.
