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 -124.153449 -122.934460 43.756118 42.920738 USGS Thesaurus inlandWaters fluvial geomorphology active channel sediment transport ISO 19115 Topic Category geoscientificInformation inlandWaters environment USGS Metadata Identifier USGS:819cd3df-38f8-40c8-90e2-5b2ec6df2125 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 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. Photographs were rectified using a second order polynomial transformation. 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 and populated with attributes for the original photograph, date flown, stream discharge, number of ground control points to register the original photograph, and root mean square error for registration. The source of the date flown was documentation present on the scanned photographs.
