The exercises were conducted during an annual reservoir flushing exercise at Cherry Creek Dam near Denver, Colorado. The instrument offers several compelling advantages, including low cost, ease of use, portability, and capability for long-term autonomous deployment. The investigation revealed challenges associated with making stable and reliable measurements; however, these drawbacks can largely be overcome through setup of a thoughtful deployment scheme and assimilation of laboratory calibration routines.\", \"distribution\": [{\"@type\": \"dcat:Distribution\", \"accessURL\": \"https://data.usbr.gov/catalog/8000/item/128574\", \"description\": \"Landing page for \\\"S&T Project 20069 Final Report: Monitoring Suspended Sediment: An Investigation Coincident with the Cherry Creek Reservoir Annual Flush\\\"\", \"mediaType\": \"text/html\", \"title\": \"RISE Item Details Page URL for \\\"S&T Project 20069 Final Report: Monitoring Suspended Sediment: An Investigation Coincident with the Cherry Creek Reservoir Annual Flush\\\"\"}, {\"@type\": \"dcat:Distribution\", \"description\": \"\\\"S&T Project 20069 Final Report: Monitoring Suspended Sediment: An Investigation Coincident with the Cherry Creek Reservoir Annual Flush\\\" as a PDF file\", \"downloadURL\": \"https://data.usbr.gov/rise/content-rise-public/rise/catalog-item/binary/Final Report ST-2023-20069-01 Monitoring Suspended Sediment Cherry Creek Reservoir Annual Flush_508 (1).pdf\", \"mediaType\": \"application/pdf\", \"title\": \"PDF File for \\\"S&T Project 20069 Final Report: Monitoring Suspended Sediment: An Investigation Coincident with the Cherry Creek Reservoir Annual Flush\\\"\"}], \"identifier\": \"https://datainventory.usbr.gov/rise/item/128574\", \"keyword\": [\"Hydroacoustics\", \"Sediment Surrogate\", \"Suspended Sediment\"], \"landingPage\": \"https://data.usbr.gov/catalog/8000/item/128574\", \"modified\": \"2024-03-05T10:47:08Z\", \"publisher\": {\"@type\": \"org:Organization\", \"name\": \"Bureau of Reclamation\"}, \"spatial\": \"{\\\"type\\\":\\\"Point\\\",\\\"coordinates\\\":[-104.855255,39.651378]}\", \"title\": \"S&T Project 20069 Final Report: Monitoring Suspended Sediment: An Investigation Coincident with the Cherry Creek Reservoir Annual Flush\"}","source_transform":null,"status":"error"}
