  • A 50-foot wide pipeline right-of-way contained an 18-inch refined product pipeline. The 18-inch pipeline crosses Dyer Ditch between a railroad corridor and a residential area in Lake County, Indiana. Downcutting of the creek bed caused the banks to become steep and unstable...

  • A 6-inch diameter natural gas pipeline crosses a canal in Miami, Florida. Sheet flow from the adjacent street and high flow events had exposed the pipeline. 3-in-1 concrete bags had been placed atop the pipeline in an effort to protect it, but the sheet flow and high flow events...

  • 20-inch products pipeline runs parallel to a railroad track in Imperial County, California. Both the pipeline and the railroad are crossed by the 250-foot wide Mammoth Wash. Flash floods caused lateral migration and eroded 3 to 6 feet of the right-descending bank.
