Index testing has been used to estimate the erodibility of different compacted embankment soils. Index tests include Hole Erosion Tests (HET) and Jet Erosion Tests (JET). These tests provide an indication of different circumstances (such as water content at placement, density, soil type) that impact a soil\\u2019s erodibility. The results of these tests are often used in risk analyses to help evaluate the likelihood of failure for Reclamation\\u2019s embankment dams. Recent large-scale erosion tests were completed and compared to HET and JET results. Results from the large-scale tests indicate water content, density, void ratio, and percent saturation have a significant impact on a soil\\u2019s erodibility. Testing on non-plastic silts and high-plasticity clays revealed surprising results. Under various conditions the erosion rate in the clay was found to be similar to the highly erodible non-plastic silts and under other variations the non-plastic silts eroded as slowly as high-plasticity clays. Results from these tests will be used in the evaluation of embankment erodibility.\", \"distribution\": [{\"@type\": \"dcat:Distribution\", \"accessURL\": \"https://data.usbr.gov/catalog/7963/item/128433\", \"description\": \"Landing page for \\\"S&T Project 8284 Final Report: Cracked Embankment Erosion Research\\\"\", \"mediaType\": \"text/html\", \"title\": \"RISE Item Details Page URL for \\\"S&T Project 8284 Final Report: Cracked Embankment Erosion Research\\\"\"}, {\"@type\": \"dcat:Distribution\", \"description\": \"\\\"S&T Project 8284 Final Report: Cracked Embankment Erosion Research\\\" as a PDF file\", \"downloadURL\": \"https://data.usbr.gov/rise/content-rise-public/rise/catalog-item/binary/Project_id = 8284 8284_Final_Report_508.pdf\", \"mediaType\": \"application/pdf\", \"title\": \"PDF File for \\\"S&T Project 8284 Final Report: Cracked Embankment Erosion Research\\\"\"}], \"identifier\": \"https://datainventory.usbr.gov/rise/item/128433\", \"keyword\": [\"Concentrated Leak Erosion\", \"Cracked Embankment\", \"Erosion\", \"Gradient\", \"Hydraulic Shear Stress\", \"Internal Erosion\", \"Scour\"], \"landingPage\": \"https://data.usbr.gov/catalog/7963/item/128433\", \"modified\": \"2023-10-12T20:29:54Z\", \"publisher\": {\"@type\": \"org:Organization\", \"name\": \"Bureau of Reclamation\"}, \"spatial\": \"{\\\"type\\\":\\\"Point\\\",\\\"coordinates\\\":[-105.12194,39.7225]}\", \"title\": \"S&T Project 8284 Final Report: Cracked Embankment Erosion Research\"}","source_transform":null,"status":"error"}
