Scour Power—An In-Depth Risk Analysis for Large Pipeline Creek Crossings
Publication: Pipelines 2021
ABSTRACT
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.
