However, emerging liner technologies have not been thoroughly evaluated in long-term, real-world settings. This study aimed to compare the performance of six liner materials\\u2014including HDPE, EPDM alloy, polyurea-impregnated geotextile, bituminous geomembrane, reinforced polyethylene, and a concrete composite\\u2014through laboratory durability testing and field trials in Oregon\\u2019s Klamath Irrigation District (KID). The project involved coordinated efforts among the Technical Service Center, KID, the Klamath Basin Area Office, and liner manufacturers. Preparations included initial seepage measurements, acquisition of testing materials, and procurement of specialized laboratory equipment. Despite substantial progress, the project was suspended due to unexpected delays in equipment delivery and the late-stage initiation of a complex environmental compliance review, which exceeded available time and budget. Although the research was not completed, key lessons were documented, emphasizing the need to account for regulatory timelines and environmental compliance in early planning stages. Future efforts will seek renewed funding to continue evaluating alternative liner materials.\", \"distribution\": [{\"@type\": \"dcat:Distribution\", \"accessURL\": \"https://data.usbr.gov/catalog/8525/item/133870\", \"description\": \"Landing page for \\\"S&T Project 23012: Investigating Innovative Exposed Lining Systems\\\"\", \"mediaType\": \"text/html\", \"title\": \"RISE Item Details Page URL for \\\"S&T Project 23012: Investigating Innovative Exposed Lining Systems\\\"\"}, {\"@type\": \"dcat:Distribution\", \"description\": \"\\\"S&T Project 23012: Investigating Innovative Exposed Lining Systems\\\" as a PDF file\", \"downloadURL\": \"https://data.usbr.gov/rise/content-rise-public/rise/catalog-item/binary/Investigating Innovative Exposed Lining Systems Report_ FINAL 508_Signed.pdf\", \"mediaType\": \"application/pdf\", \"title\": \"PDF File for \\\"S&T Project 23012: Investigating Innovative Exposed Lining Systems\\\"\"}], \"identifier\": \"https://datainventory.usbr.gov/rise/item/133870\", \"keyword\": [\"Canal Lining\", \"Canal Seepage\", \"Canals\"], \"landingPage\": \"https://data.usbr.gov/catalog/8525/item/133870\", \"modified\": \"2025-10-30T16:58:43Z\", \"publisher\": {\"@type\": \"org:Organization\", \"name\": \"Bureau of Reclamation\"}, \"spatial\": \"{\\\"type\\\":\\\"Polygon\\\",\\\"coordinates\\\":[[[-105.12484,39.72238],[-105.1217,39.72366],[-105.1199,39.72123],[-105.12164,39.72052],[-105.12285,39.72213],[-105.12431,39.72153],[-105.12484,39.72238]]]}\", \"title\": \"S&T Project 23012: Investigating Innovative Exposed Lining Systems\"}","source_transform":null,"status":"error"}
