In cooperation with the Portland District \nof the U.S. Army Corps of Engineers (USACE), the USGS evaluated sediment transport and gravel storage \nalong the downstream alluvial reaches of the North and South Umpqua Rivers and the entire mainstem Umpqua \nRiver. This includes the lower 46.8 kilometers (29.1 miles) of the North Umpqua River and the lower 122.6 \nkilometers (76.2 miles) of the South Umpqua River. \n\t\t\nThe Umpqua River gravel transport study involved multiple analyses, including tracking patterns of historical \nchannel change and estimation of a sediment budget. To support these analyses, digital channel maps were \nproduced to depict channel and floodplain conditions along the Umpqua River system from different time periods.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9BRJSHJ", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.8a35d28a-25ba-438e-9b98-18181288d39e.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_8a35d28a-25ba-438e-9b98-18181288d39e", "keyword": ["Douglas County", "Oregon", "USGS:8a35d28a-25ba-438e-9b98-18181288d39e", "Umpqua River", "active channel", "environment", "fluvial geomorphology", "geoscientificInformation", "inlandWaters", "sediment transport"], "modified": "2020-11-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-123.514668, 43.268110, -123.432823, 43.378243", "theme": ["geospatial"], "title": "Umpqua River Oregon Garden Valley PhotoMosaic 1939"}
