The source data sets \nwere derived from tabular National Resource Inventory (NRI) data sets created by \nthe National Resources Conservation Service (NRCS, U.S. Department of Agriculture, \n1995, 2000).  Artificial drainage is defined as subsurface drains and ditches.  Irrigation \ntypes are defined as gravity and pressure.  Subsurface drains are described as conduits, \nsuch as corrugated plastic tubing, tile, or pipe, installed beneath the ground surface to \ncollect and/or convey drainage. Surface drainage field ditches are described as graded \nditches for collecting excess water.  Gravity irrigation source is described as irrigation \ndelivered to the farm and/or field by canals or pipelines open to the atmosphere; and \nwater is distributed by the force of gravity down the field by: (1) A surface irrigation \nsystem (border, basin, furrow, corrugation, wild flooding, etc.) or (2) Sub-surface \nirrigation pipelines or ditches. Pressure irrigation source is described as irrigation \ndelivered to the farm and/or field in pump or elevation-induced pressure pipelines, \nand water is distributed across the field by: (1) Sprinkle irrigation (center pivot, \nlinear move, traveling gun, side roll, hand move, big gun, or fixed set sprinklers), \nor (2) Micro irrigation (drip emitters, continuous tube bubblers, micro spray or micro \nsprinklers). NRI data do not include Federal lands and are thus excluded from this \ndataset.

This is one of \nthree data layers in this data series publication.","distribution_titles":["Digital Data","Original Metadata"],"harvest_record":"https://catalog.data.gov/harvest_record/4c30ee7c-318e-430f-a7de-fb1cf1e5a88a","harvest_record_raw":"https://catalog.data.gov/harvest_record/4c30ee7c-318e-430f-a7de-fb1cf1e5a88a/raw","has_download":true,"has_spatial":true,"identifier":"http://datainventory.doi.gov/id/dataset/USGS_9d533fb8-26a1-4be3-ba76-faa866030ebc","keyword":["USGS:9d533fb8-26a1-4be3-ba76-faa866030ebc","environment","geoscientificInformation","inland waters","inlandWaters"],"last_harvested_date":"2026-08-31T18:18:16.625990","organization":{"aliases":["dept"],"code_repo_exempt":false,"code_repo_url":null,"description":null,"id":"143529f7-2eef-4a07-b227-93ac9e84fad8","logo":"https://raw.githubusercontent.com/GSA/logo/master/doi.png","name":"Department of the Interior","organization_type":"Federal Government","slug":"doi"},"parent_identifier":null,"popularity":2,"publisher":"U.S. Geological Survey","slug":"massachusetts-hydrologic-unit-subdivisions","spatial_centroid":{"lat":42.042474600000006,"lon":-72.3780616},"spatial_shape":{"coordinates":[[[-73.58413,41.463959],[-73.58413,42.910248],[-70.568959,42.910248],[-70.568959,41.463959],[-73.58413,41.463959]]],"type":"Polygon"},"theme":["geospatial"],"title":"Massachusetts hydrologic unit subdivisions","type":"dataset"},{"_score":8.016453,"_sort":[1788200292310,8.016453,2,"28cf2270-aaba-4e36-9fca-8765c1f93d3c"],"dcat":{"accessLevel":"public","bureauCode":["010:12"],"contactPoint":{"@type":"vcard:Contact","fn":"Kerri Hitt.","hasEmail":"mailto:khitt@usgs.gov"},"description":"This data set represents predicted nitrate concentration in\nground water used for drinking, in milligrams per liter, in the\nconterminous United States, and was generated by a national\nnonlinear regression model based on 14 input parameters.\n\nNolan and Hitt (2006) developed two national models to predict\ncontamination of ground water by nonpoint sources of\nnitrate.

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.\n\t\t\nGIS layers defining the active channel of the Umpqua River system were developed for three time periods: \n1939, 1967, and 2005. For the South Umpqua River and the 19 kilometers (12 miles) of the mainstem \nUmpqua River downstream from the confluence of the North and South Umpqua Rivers, GIS layers were \nalso developed for the time periods 1994, 2000, and 2009.\n\t\t\nFor this project, the active channel was defined as area typically inundated during annual high flows, and \nincludes the low-flow channel as well as side channels, islands, and channel-flanking gravel bars. The active \nchannel datasets were developed by digitizing from aerial photographs. Aerial photographs from 1939 and \n1967 were scanned, rectified, and mosaiced for this project. Digital orthophotographs from 1994, 2000, \n2005, and 2009 are publicly available (See metadata for each photograph set for more information on the \nrectification process and resolution of each dataset). Although our study area encompasses the Umpqua \nRiver and lower reaches of the North and South Umpqua Rivers, the extent of each dataset depended \nupon the underlying aerial photographs; for example, the 1967 photographs extend only as far downstream \nas floodplain kilometer 7, whereas the 1939 and 2005 datasets extend to the mouth of the Umpqua River \nat the Pacific Ocean.","distribution_titles":["Digital Data","Original Metadata"],"harvest_record":"https://catalog.data.gov/harvest_record/1711fd20-ab45-48ee-8fe7-58fa15b367b3","harvest_record_raw":"https://catalog.data.gov/harvest_record/1711fd20-ab45-48ee-8fe7-58fa15b367b3/raw","has_download":true,"has_spatial":true,"identifier":"http://datainventory.doi.gov/id/dataset/USGS_d15a840e-bf21-49e4-9c90-79aa9d397443","keyword":["Douglas County","Oregon","USGS:d15a840e-bf21-49e4-9c90-79aa9d397443","Umpqua River","active channel","environment","fluvial geomorphology","geoscientificInformation","inlandWaters","sediment transport"],"last_harvested_date":"2026-08-31T18:13:03.503438","organization":{"aliases":["dept"],"code_repo_exempt":false,"code_repo_url":null,"description":null,"id":"143529f7-2eef-4a07-b227-93ac9e84fad8","logo":"https://raw.githubusercontent.com/GSA/logo/master/doi.png","name":"Department of the Interior","organization_type":"Federal Government","slug":"doi"},"parent_identifier":null,"popularity":2,"publisher":"U.S. Geological Survey","slug":"umpqua-river-oregon-roseburg-photomosaic-1967","spatial_centroid":{"lat":43.0754046,"lon":-123.39131},"spatial_shape":{"coordinates":[[[-123.45702,42.946187],[-123.45702,43.269231],[-123.292745,43.269231],[-123.292745,42.946187],[-123.45702,42.946187]]],"type":"Polygon"},"theme":["geospatial"],"title":"Umpqua River Oregon Roseburg PhotoMosaic 1967","type":"dataset"},{"_score":7.544568,"_sort":[1788199971533,7.544568,5,"0c5a52c1-b76b-4750-a3bc-736de54773ea"],"dcat":{"accessLevel":"public","bureauCode":["010:12"],"contactPoint":{"@type":"vcard:Contact","fn":"Karen Hanson","hasEmail":"mailto:khanson@usgs.gov"},"description":"This map shows specific water-quality items and hydrologic data site\ninformation which come from QWDATA (Water Quality) and GWSI (Ground\nWater Information System).
