O'Connor Scott Anderson Mackenzie Keith Charles Cannon John Risley 2010 document Wallick, J.R., O'Connor, J.E., Anderson, Scott, Keith, Mackenzie, Cannon, Charles and Risley, John, 2010, Channel change and bed-material transport, Umpqua River, Oregon: U.S. Geological Survey Open-File Report 2010-1314. https://pubs.usgs.gov/of/2010/1314/ The Umpqua River drains 12,103 square kilometers (4,673 square miles) in southwest Oregon before flowing into the Pacific Ocean at Winchester Bay near the city of Reedsport. In cooperation with the Portland District of the U.S. Army Corps of Engineers (USACE), the USGS evaluated sediment transport and gravel storage along the downstream alluvial reaches of the North and South Umpqua Rivers and the entire mainstem Umpqua River. This includes the lower 46.8 kilometers (29.1 miles) of the North Umpqua River and the lower 122.6 kilometers (76.2 miles) of the South Umpqua River. The Umpqua River gravel transport study involved multiple analyses, including tracking patterns of historical channel change and estimation of a sediment budget. To support these analyses, digital channel maps were produced to depict channel and floodplain conditions along the Umpqua River system from different time periods. GIS layers defining the active channel of the Umpqua River system were developed for three time periods: 1939, 1967, and 2005. For the South Umpqua River and the 19 kilometers (12 miles) of the mainstem Umpqua River downstream from the confluence of the North and South Umpqua Rivers, GIS layers were also developed for the time periods 1994, 2000, and 2009. For this project, the active channel was defined as area typically inundated during annual high flows, and includes the low-flow channel as well as side channels, islands, and channel-flanking gravel bars. The active channel datasets were developed by digitizing from aerial photographs. Aerial photographs from 1939 and 1967 were scanned, rectified, and mosaiced for this project. Digital orthophotographs from 1994, 2000, 2005, and 2009 are publicly available (See metadata for each photograph set for more information on the rectification process and resolution of each dataset). Although our study area encompasses the Umpqua River and lower reaches of the North and South Umpqua Rivers, the extent of each dataset depended upon the underlying aerial photographs; for example, the 1967 photographs extend only as far downstream as floodplain kilometer 7, whereas the 1939 and 2005 datasets extend to the mouth of the Umpqua River at the Pacific Ocean. These data were created to support the evaluation of sediment transport and gravel storage in the alluvial reaches of the Umpqua River system, Oregon. This mapping was used to track changes in channel morphology over time and to measure changes in gravel bar area and channel position. 1967 Ground condition Complete None planned -123.446310 -123.099766 43.320659 43.263640 USGS Thesaurus inlandWaters fluvial geomorphology active channel sediment transport ISO 19115 Topic Category geoscientificInformation inlandWaters environment USGS Metadata Identifier USGS:e3085cda-0f19-4ec2-b505-2f6cf45a8eeb Geographic Names Information System Umpqua River Oregon Douglas County None The U.S. Geological Survey should be acknowledged as the data source in products derived from these data.

The data are complete. The 1967 photographs were generally registered with 12 to 17 ground control points. The number of control points used ranged from 8 to 22. Root mean square error was generally between 1.4 and 3.0 meters, and ranged from 0.9 to 4.3 meters. Spot checks comparing the 1967 mosaics to NAIP digital orthophotographs from 2005 suggest that errors in image alignment are generally less than 6 meters, but may be as high as 16 meters.

The photographs were scanned by University of Oregon Map and Aerial Photography Library staff in Eugene, Oregon. USDA 1967 2009 The photographs were registered in ArcGIS 9.3, using National Agriculture Imagery Program (NAIP) 0.5 meter resolution digital orthophotographs acquired in 2005 as a base layer. Ground control points were generally building corners or bedrock outcrops. At times, road intersections, distinctive road bends, or individual trees were used as control points. Most control points were selected from within or near the geomorphic floodplain. NAIP 2005 2009 The photographs were rectified using the Georeferencing Toolbar in ArcMap. The registered photographs were rectified using a second order polynomial transformation. Georeferenced photographs were resampled to a cell size of 0.5 meter using bilinear interpolation in Georeferencing Toolbar in ArcGIS 9.3. The cell size of 0.5 meter was selected for uniformity, so the rectified images could be mosaiced. 2009 The rectified images were mosaiced into an ESRI file geodatabase raster dataset and were clipped to include only the area within the floodplain where the control points had been concentrated. They were also clipped to our study reaches to improve display efficiency. 2009 The polygons used to clip the photographs were merged into a feature dataset and populated with attributes for the original photograph identifier, date flown, stream discharge, number of ground control points to register the original photograph, and root mean square error for registration. 2009 Photo_Data_1967 Raster String 7 Universal Transverse Mercator 10 0.999600 -123.000000 0.000000 500000.000000 0.000000 row and column 0.500000 0.500000 meters North American Datum of 1983 Geodetic Reference System 80 6378137.000000 298.257222 U.S. Geological Survey Michael Ierardi IT Specialist mailing address
