As unsteady flow models are increasingly used to accurately model flood management infrastructure impacts, National Flood Insurance Program (NFIP) requirements will make it common for engineers to reproduce FEMA's regulatory, steady-flow-modeled peak elevations within a baseline unsteady flow framework. This study reproduces FEMA's steady flow hydraulic analysis of the Truckee River from Tahoe City to the Placer County boundary using an unsteady flow HEC-RAS model. The process uses entirely publicly accessible information from FEMA's Flood Insurance Study (FIS) report, the National Flood Hazard Layer (NFHL) spatial database, and the USGS National Map Digital Elevation Model (DEM) database. The channel baseline as surveyed during the original FEMA flood study is used to approximate the channel bathymetry and recondition a USGS digital elevation model that did not penetrate the water surface. Uniform lateral inflow hydrographs were prepared to spatially match the peak flowrates produced in FEMA's flood study and recorded in the FIS report. The model was calibrated to match the peak 100-year stages to the 100-year water surface elevation profile in the report. The calibration process was validated by comparing the modeled peak stages for the 10-, 50-, and 500-year floods to the corresponding elevation profiles. This procedure proves that it is possible to reproduce FEMA's steady flow hydraulic analysis using FIS-documented historical invert survey data and peak discharges along with widely available USGS terrain data for the floodplain.
