... Reconnaissance, Geohazards. INTRODUCTION In general, a landslide is defined as the movement of a mass of rock, debris, or earth down a slope, and encompasses geologic processes such as debris or mud flows, rotational slides (slumps), translational slides, earth flows, rock falls, or debris slides [1, 2...

... on risk management principles. The procedure was implemented on the OSSA-1 pipeline as part of a pilot study. This paper describes the OSSA-1 Pilot Project, with emphasis on how risk assessment procedures were customized to address the pipeline’s elevated exposure to ‘geohazards’. Geohazards...

... 10 12 2008 Natural hazards (also known as ground movement or geohazards) can cause pipeline failures, with consequences ranging from injury/death, environmental impact, and property damage, to lengthy service disruption and a failure to achieve delivery targets. In North America...
