Information about the study, flood and methods used can be found in the USGS Scientific Investigations Report 2011-5045. http://pubs.usgs.gov/sir/2011/5045/ Purpose: This dataset was created to support the development of flood-peak inundation maps for documenting the extent of the September 2010 flood along a reach of the Straight River and Cannon River in Faribault, MN. Supplemental_Information: A GIS application was used to produce a plane representing the flood-peak water surface. The application duplicates the high-water-mark elevation data points across the flood plain perpendicular to the direction of the flood flow (Moon Kim, U.S. Geological Survey, written commun., January 2011). Elevations between high-water marks are proportional interpolations of the high-water-mark data and were positioned to generate a flood surface sloping with the water flow. A triangular irregular network (TIN) surface was created with the data points (TIN-generated surfaces pass exactly through the data-point elevations), forming the estimated flood surface. A flood-depth grid was made by subtracting the DEM from the flood surface. The flood-peak inundation areas are available in a GIS format that provides extent of the flood peak. This format allows the GIS data to be overlain on maps and aerial photographs, and to be used for various GIS applications, such as FEMA's Hazards U.S. Multi-Hazards (HAZUS-MH) program (Federal Emergency Management Agency, 2010b) to estimate flood damages.

The ArcGIS geodatabase topology tools were used to make corrections using 11 rules including no gaps, no overlaps, identify cooresponding linework for every polygon boundary, and remove duplicate lines with the same beginning and ending nodes. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Flood inundation extent was manually checked by sampling the digital elevation model (DEM) adjacent to high water marks. This check was done to verify that DEM elevations greater than the high-water mark were not in the flood inundation polygon and elevations less than the high water mark were within the flood inundation polygon.
