Land use planning for high pressure pipelines : ground hazards from landsliding

Landsliding is a significant geological hazard in the UK and can cause localised damage to built structures including buried pipelines. Detailed investigation is required to establish the true nature and risk of landsliding at a site but this is a costly and time-consuming process that is unnecessary in many instances. Although widespread in occurrence landslides tend to occur only in certain areas where geological, geomorphological and environmental conditions are conducive to failure. Thus it is possible, by assessing existing records and experience to gain some indication of the susceptibility to landsliding of any particular location. In order to assess, on a national scale, the hazard to the high-pressure gas pipeline network from landsliding, Advantica Technologies commissioned the British Geological Survey (BGS) to collate available information regarding landslide hazards across the UK and present them in a way meaningful to the pipeline operators. The results of this research are presented in this report and accompanying data cd.
