This presentation discusses an approach for detailed scour risk analysis of creek crossings for design of large diameter water transmission lines. Discussion includes risk categorization and methodologies utilized, including the City of Austin’s erosion hazard zone methodology and the United States Bureau of Reclamation Guidelines for evaluating pipeline channel crossing hazards to ensure effective burial. The presentation describes how tailored scour analysis for the Alliance Regional Water Authority’s Phase 1B treated water pipeline segment A resulted in informed design decisions, lower construction costs, and thoughtful creek crossing restoration.

Scour Power—An In-Depth Risk Analysis for Large Pipeline Creek Crossings

Papers from sessions of Pipelines 2021, held virtually August 3–6, 2021. Sponsored by the Utility Engineering and Surveying Institute of ASCE. The conference provides a forum for pipeline engineers and practitioners from all around the world to share their experiences in meeting the challenges of today's pipeline infrastructure. This premier industry event has become the conference of choice for utility and pipeline owners, design and consulting engineers, contractors, manufacturers, suppliers, students, educators, researchers, and pipeline professionals. The conference includes surveying as it relates to pipeline and utility projects. This event will provide a dynamic and inspiring venue for participants to share and gain valuable knowledge related to planning, designing, constructing, renewing, operating, managing and maintaining the pipeline assets.
