The profile baseline shows the path of flood flows on the FIRM and is an accurate representation of the distance between cross sections, structures, nodes, or grids in the hydraulic model. The profile baseline is used for replicating the stationing and water-surface elevations found in the FIS report profiles, but in GIS format. This information is used in the following tables within the FIS report: Flooding Sources Included in this FIS report, Principal Flood Problems, Summary of Hydrologic and Hydraulic Analyses, Summary of Topographic Elevation Data Used in Mapping, the Stream-by_Stream Vertical Datum Conversion, and Summary of Contracted Studies Included in this FIS Report. |
