“…Taking these potential uncertainties into consideration, Kelly and Rydlund (2006) note that errors and variations in data rarely occur in only one direction; rather, a combination of errors and uncertainties of varying value and sign is more likely to occur. However, to account for these uncertainties, it is recommended to evaluate not only the flood-inundation map for the stage of interest, but also the maps associated with stages of less than and greater than the stage of interest (Kelly and Rydlund, 2006).…”

“…Water-surface elevations along the stream reaches were estimated by steady-state hydraulic modeling, assuming unobstructed flow, and using streamflows and hydrologic conditions anticipated at the USGS streamgage. As discussed by Kelly and Rydlund (2006), hydraulic models are approximations of actual streamflow, and simulated discharge and stage typically deviate from reality.…”

“…Consequently, there is a lower confidence in the accuracy of flood-inundation maps for stages that have comparatively greater differences between modeled and observed water-surface elevations. As suggested by Kelly and Rydlund (2006), evaluation of flood-inundation maps for values of stage both greater and less than the stage of interest is recommended. Differences between observed and modeled water levels for the December 2, 2010, flood profile ranged from -0.4 to +0.3 ft throughout the study reach (table 5).…”

Flood-Inundation Maps for the West Branch Susquehanna River near the Boroughs of Lewisburg and Milton, Pennsylvania, 2013By Mark A. Roland and Scott A. Hoffman AbstractDigital flood-inundation maps for an approximate 8-mile reach of the West Branch Susquehanna River from approximately 2 miles downstream from the Borough of Lewisburg, extending upstream to approximately 1 mile upstream from the Borough of Milton, Pennsylvania, were created by the U.S. Geological Survey (USGS) in cooperation with the Susquehanna River Basin Commission (SRBC). The inundation maps, which can be accessed through the USGS Flood Inundation Mapping Science Web site at http://water.usgs.gov/osw/ flood_inundation/, depict the estimated areal extent and depth of flooding corresponding to selected water levels (stages) at the USGS streamgage 01553500, West Branch Susquehanna River at Lewisburg, Pa.

Flood inundation maps typically have been used to depict inundated areas for floods having specific exceedance levels. The uncertainty associated with the inundation boundaries is seldom quantified, in part, because all of the sources of uncertainty are not recognized and because data available to quantify uncertainty seldom are available. Sources of uncertainty discussed in this paper include hydrologic data used for hydraulic model development and validation, topographic data, and the hydraulic model. The assumption of steady flow, which typically is made to produce inundation maps, has less of an effect on predicted inundation at lower flows than for higher flows because more time typically is required to inundate areas at high flows than at low flows. Difficulties with establishing reasonable cross sections that do not intersect and that represent water‐surface slopes in tributaries contribute additional uncertainties in the hydraulic modelling. As a result, uncertainty in the flood inundation polygons simulated with a one‐dimensional model increases with distance from the main channel.
