Simulations cover the Delta-X Spring and Fall campaigns in 2021 and include hydrodynamics, waves, and sediment transport. Bottom friction was calibrated using AirSWOT water elevation data, while sediment parameters were calibrated using AVIRIS-NG Total Suspended Solids (TSS) data. All files required to run the simulations are included. Model output of water levels, velocity, and depth-averaged sediment concentration are provided for both campaigns as netCDF files. The dataset includes a netCDF file containing the annual inorganic mass accumulation rates derived from simulations.", "distribution": [{"@type": "dcat:Distribution", "conformsTo": "http://www.isotc211.org/2005/gmi", "description": "The metadata's original source.", "downloadURL": "https://cmr.earthdata.nasa.gov/search/concepts/C2857065166-ORNL_CLOUD.iso19115", "format": "ISO", "mediaType": "text/xml", "title": "Original Metadata"}, {"@type": "dcat:Distribution", "downloadURL": "https://daac.ornl.gov/DELTAX/guides/DeltaX_Delft3D_Atchafalaya_MRD_Fig1.jpg", "format": "JPEG", "mediaType": "image/jpeg"}, {"@type": "dcat:Distribution", "downloadURL": "https://data.ornldaac.earthdata.nasa.gov/public/deltax/DeltaX_Delft3D_Atchafalaya_MRD/comp/DeltaX_Delft3D_Atchafalaya_MRD.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://deltax.jpl.nasa.gov/", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://doi.org/10.3334/ORNLDAAC/2302", "format": "HTML", "mediaType": "text/html"}, {"@type": "dcat:Distribution", "downloadURL": "https://opendap.earthdata.nasa.gov/", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://search.earthdata.nasa.gov/search/granules?p=C2857065166-ORNL_CLOUD", "format": "BIN", "mediaType": "application/octet-stream"}], "identifier": "10.3334/ORNLDAAC/2302", "keyword": ["earth-science-ecosystems-biosphere-marine-ecosystems", "earth-science-erosion-sedimentation-land-surface-sediment-composition", "earth-science-erosion-sedimentation-land-surface-sediment-transport", "earth-science-surface-water-terrestrial-hydrosphere-surface-water-processes-measurements"], "license": "https://www.usa.gov/government-works", "modified": "2026-06-22", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "ORNL_DAAC"}, "spatial": "[\"CARTESIAN\", [{\"WestBoundingCoordinate\": -91.8697, \"NorthBoundingCoordinate\": 29.8218, \"EastBoundingCoordinate\": -90.9994, \"SouthBoundingCoordinate\": 29.1725}]]", "temporal": "2021-03-20/2021-08-28", "theme": ["Earth Science"], "title": "Delta-X: Delft3D Broad-Scale Sediment Model, Atchafalaya Basin, MRD, Louisiana, USA"}
