The Pacific Gas & Electric Company (PG&E) natural gas transmission system consists of approximately 6,800 miles of gas transmission pipeline traversing nine of the eleven unique geomorphic provinces of California. In this dynamic geologic environment, it is inevitable that extensive linear assets such as gas transmission pipelines will be affected by geohazards such as landslides and erosion. Geohazard-related ground movement can result in increased bending strain which in turn can lead to permanent pipe deformation and possibly failure. Asset owners must therefore develop strategies for assessing and managing these geohazards and associated asset risk.

This paper provides an overview...
