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.
