Pore pressure variability and control is one of the most significant aspects of Geotechnical Engineering practice related to slope stability, underground openings, foundation of heavy structures, and water retention facilities. Pore pressure effects are most often controlled by natural small-scale hydrogeologic details. Characterization and management of pore pressures requires closely-arrayed repeated measurements to determine the effects of these details for design of appropriate mitigation measures, for performance monitoring and control of the selected mitigation measure. Since the late 1970’s the Westbay System has been used on some of the largest landslide studies in the world.

Pipeline management presents challenges that are quite unique. Their long length, high value, high risk and often difficult access conditions require continuous monitoring as well as an optimization of maintenance interventions. The main concern for pipeline owners comes from possible leakages that can have a severe impact on the environment and put the pipeline out of service for repair. Leakages can have different causes, including excessive deformations caused by earthquakes, landslides or collisions mobile objects, corrosion, wear, material flaws or third party intrusion.
