Each local source is defined independently and may have several constituents. Model results include the fate of each constituent from each local source. PTM simulates particle transport using precalculated, periodically saved hydrodynamic (and wave) model output from state of the art models. PTM uses processes vital to constituent transport including but not limited to advection, diffusion, settling, deposition, and resuspension. The PTM interface is in the Surface-water Modeling System, which provides a user-friendly environment for input development, model execution, data analysis, and visualization.\\u00a0</div>\", \"distribution\": [{\"@type\": \"dcat:Distribution\", \"accessURL\": \"https://geospatial-usace.opendata.arcgis.com/documents/1ca263d5bb48481cb851c78a1e484d9c\", \"format\": \"Web Page\", \"mediaType\": \"text/html\", \"title\": \"ArcGIS Hub Dataset\"}], \"identifier\": \"https://www.arcgis.com/home/item.html?id=1ca263d5bb48481cb851c78a1e484d9c\", \"issued\": \"2018-03-27T17:32:49.000Z\", \"keyword\": [\"Fact Sheets\", \"RSM\", \"RSM: Evaluating Alternatives - Hydrodynamic and Sediment Transport Modeling\", \"RSM: Phase 2 - Evaluate RSM Strategies\"], \"landingPage\": \"https://geospatial-usace.opendata.arcgis.com/documents/1ca263d5bb48481cb851c78a1e484d9c\", \"license\": \"\", \"modified\": \"2018-06-21T14:36:37.000Z\", \"programCode\": [\"202:202-000\"], \"publisher\": {\"name\": \"US Army Corps of Engineers\"}, \"spatial\": \"\\\"\\\"\", \"theme\": [\"geospatial\"], \"title\": \"RSM Tool: PTM Fact Sheet\"}","source_transform":null,"status":"error"}
