Publication_Date: 2011 Title: Map of debris flows caused by rainfall during 1996 in parts of the Reedsport and Deer Head Point quadrangles, southern Coast Range, Oregon Edition: Version 1.0 Geospatial_Data_Presentation_Form: map and raster digital data Series_Information: Series_Name: U.S. Geological Survey Open File Report Issue_Identification: 2011-1150 Publication_Information: Publication_Place: Denver, Colorado Publisher: U.S. Geological Survey Online_Linkage: http://pubs.usgs.gov/of/2011/1150/ Description: Abstract: This 1:12,000-scale map shows an inventory of debris flows caused by rainfall during 1996 in a 94.4 km2 area in the southern Coast Range of Oregon. This map and associated digital data are part of a larger U.S. Geological Survey study of debris flows in the southern Coast Range. Available evidence indicates that the flows were triggered by a rain storm that occurred between November 17 and 19. The closest rain gage in the Coast Range (Goodwin Peak) recorded 245 mm during the storm. Maximum rainfall intensity during the storm was 13.2 mm/hr on November 18. Debris flows were photogrammetrically mapped from 1:12,000-scale aerial photographs flown in May, 1997. The inventory is presented on imagery derived from LiDAR data acquired in 2008. We classified mapped debris flows into four categories based on the type of debris-flow activity: (1) discrete slide source areas, (2) predominantly erosion, (3) predominantly transport or mixed erosion and deposition, and (4) predominantly deposition. Locations of woody-debris jams are also shown on the map. The area encompassed by debris flows is 2.1 percent of the 94.4 km2 map area. This data set is the raster representation of the bare earth surface elevation for the extent of the map, derived from the LiDAR imagery. The data are available for download and analysis by the user. These data are shown as a hillshade representation with the debris-flow inventory polygons overlain in map. Purpose: These data are part of a larger USGS study of the debris-flow in the southern Coast Range of Oregon. Supplemental_Information: The methods and background used to create these data are described fully within the text accompanying the maps. It is strongly suggested that the user consult the text and be familiar with limitations in the methodology when using this data set. This raster data set, "1150lidarelev", represents the bare earth surface elevation for the extent of map, derived from the LiDAR imagery, is available for download by the user. These data are shown as a hillshade representation with the debris-flow inventory polygons overlain in map. Three additional vector data sets that are shown on map are also available for download: 1) "1150DebrisFlowPolygons" which were photgrammetrically mapped from aerial photos; 2) "1150MappingExtent" which represents the polygon defining the extent of mapping for map, and 3) "1150WoodyDebrisJam" which represents general point locations for the Woody-debris jam locations shown on map. Data on map of this report are shown with base layers obtained from the Oregon Spatial Data Library. The data are available for download: http://spatialdata.oregonexplorer.info/GPT9/catalog/download/download.page Available layers include roads and hydrography.

See Process_Description below. Lineage: Process_Step: Process_Description: Map portrays the mapped debris flows on a shaded-relief base map that was generated from LiDAR elevation imagery that were acquired in 2008 and made available to us in 2009. The original imagery were converted into ESRI grid-format elevation rasters. ArcGIS raster tools were used for further analysis, including use of the "Fill" tool for eliminating spurious sinks in the continuous elevation raster. The data set we are making available, "1150lidarelev", is the filled elevation raster. A more detailed discussion is found in the accompanying text.
