PR635-203904-R01 In-situ Instrumentation and Remote Sensing Methods for Slope Monitoring for Pipelines

Abstract

This research project will focus on a comparison of several in-situ methods and two remote sensing technologies, GBInSAR and InSAR. Geo-monuments and extensometers were used to measure the changes in surface movements (i.e., tension cracks) over time, and then compared to GBInSAR data for accuracy. This research project includes a comparison of spatial and in-situ monitoring systems that was performed on a steep slope with natural gas pipeline located in the Appalachian region of the United States. This report includes an integrated approach to characterize landside movement using the GBInSAR, InSAR, and in-situ methods for monitoring an active slope with an existing natural gas pipeline. The overall objective of the comparison research is to determine the reliability of the remote sensing methods compared with in-situ instrumentation for slope monitoring, that will ultimately reduce risk and increase pipeline infrastructure integrity.
