In cooperation with the U.S. Army Corps of Engineers, the U.S. Geological Survey completed a reconnaissance-level assessment of channel condition and bed-material transport relevant to the permitting of in-stream gravel extraction in the lower 12.4 kilometers Hunter Creek. To support these analyses, digital channel maps were produced to depict channel and floodplain conditions along the Hunter Creek system from different time periods. GIS layers defining the wetted channel and bar features and channel centerline of Hunter Creek were developed for four time periods: 1940, 1965, 2005, 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 wetted channel and bar feature datasets were developed by digitizing from aerial photographs. Aerial photographs from 1940 and 1965 were scanned, rectified, and mosaicked for this project (See metadata for each photograph set for more information on the rectification process and resolution of each dataset). Digital orthophotographs from 2005 and 2009 are publicly available. These data were created to support preliminary assessment of channel stability and bed-material transport on Hunter Creek, southwest Oregon. This mapping was used to track changes in channel morphology and planform over time. 1965 ground condition Complete None planned -124.422596 -124.349888 42.390736 42.347636 ISO 19115 Topic Categories inlandWaters None sediment transport fluvial geomorphology historical channel change channel stability Geographic Names Information System (GNIS) Oregon Coast Range Curry County Hunter Creek None The U.S. Geological Survey should be acknowledged as the data source in products derived from these data.

The channel centerline was reviewed and manually edited by team members to ensure that linework did not intersect bar features. Data are complete. Channel centerline mapping was reviewed by a minimum of three team members to ensure protocol was followed and that mapping was consistent between time periods. Digitizing was done at a scale of 1:2,000. Centerlines were digitized along the center of the wetted channel. Best judgment was used to determine the wetted channel boundary where obscured by vegetation or shadows. The 1940 and 1965 aerial photographs were georeferenced with a minimum of 15 ground-control points concentrated near the main channel and rectified with a second-order polynomial transformation. The total root mean square error values of the rectified photographs from 1940 and 1965 indicated that horizontal-position uncertainties associated with the georectification process ranged from 2.9 to 5.9 meters, but averaged 5.8 meters for the 1940 photographs and 3.7 meters for the 1965 photographs. Digitizing was done at a scale of 1:2,000. Wallick, J. Rose Jim E.

U.S. Department of Agriculture, Soil Conservation Service unknown remote sensing image 20000 aerial photograph 19650622 19650813 ground condition SCS-USDA 1965 The aerial photographs provided a base layer from which channel features were delineated. The 1940 and 1965 photographs were georeferenced with a minimum of 15 ground-control points concentrated near the main channel and rectified with a second-order polynomial transformation. The total root mean square error values of the rectified photographs from 1940 and 1965 indicated that horizontal-position uncertainties associated with the georectification process ranged from 2.9 to 5.9 meters, but averaged 5.8 meters for the 1940 photographs and 3.7 meters for the 1965 photographs. Since control points were concentrated near the channel, error associated with mapped features along channel corridor should be lower than the total root mean square error values for the entire photograph. 2011 Channel centerlines were digitized along the center of the wetted channel through the study area using a polyline feature class. 2011 Delineation of bars, channel centerlines, and wetted-channel edges was verified by project team members to ensure consistent delineation of features among years and throughout the study area and consistency with the delineation protocol of Wallick and others (2011). 2011 The polylines were intersected with a polygon feature class of the study reaches to limit mapping extent and assign reach names using the "Intersect" tool in ArcToolbox. 2011 Vector String 2 Transverse Mercator 0.9996 -123.0 0.0 500000.0 0.0 coordinate pair 0.0001 0.0001 Meter D North American 1983 GRS 1980 6378137.0 298.257222101 ofr2011_1160_Hunter_Creek_Centerline_1965 Hunter Creek channel centerline U.S. Geological Survey OBJECTID Internal feature number ESRI Sequential unique whole numbers that are automatically generated SHAPE Feature geometry ESRI Coordinates defining the features River Mainstem channel that contains the feature object U.S. Geological Survey Hunter Creek Mainstem Hunter Creek between river kilometer 12.4 and 0.0 U.S. Geological Survey Other Active channel in the study area that is not on the mainstem Hunter Creek U.S. Geological Survey Reach_ID Study reach that contains the feature object U.S. Geological Survey Upper Hunter Creek River kilometer 12.4 to river kilometer 6.0 along Hunter Creek U.S. Geological Survey Lower Hunter Creek River kilometer 6.0 to river kilometer 0.0 along Hunter Creek U.S. Geological Survey SHAPE_Length Length of feature in meters ESRI Positive real numbers that are automatically generated U.S. Geological Survey Ask USGS -- Water Webserver Team mailing
