TXT-tool 1.064-1.1 Field guide for the identification and assessment of landslide and erosion features and related hazards affecting pipelines

Abstract

This Field Guide was originally prepared by GNS Science in 2007 as part of the Institute of Geological and Nuclear Science (GNS Science) Short Course on the Identification and Assessment of Landslide and Erosion Hazards aimed at pipeline overseers and technicians. The guide was originally designed as a reference for technicians to use in the field during pipeline inspections, but can also be applied to other engineered structures. It contains background information on landslides and other erosion processes, including: some definitions; a short glossary of relevant landslide terms; discussion on observation and recording of geological and geomorphic information in the field; a landslide and erosion classification scheme developed for pipeline technicians; and an example “Relative Hazard Exposure Matrix” that could be used as an initial tool to assess and rank the potential consequences to a pipeline should landslide and other erosion hazards occur.
