TRB has published a new Synthesis Report entitled Advances in Unstable Slope Instrumentation and Monitoring. From the official description:
Geotechnical instrumentation and monitoring technologies have been used to inform safety, operational, and treatment decisions for unstable slopes.
The TRB National Cooperative Highway Research Program’s NCHRP Synthesis 554: Advances in Unstable Slope Instrumentation and Monitoring documents and synthesizes the state of practice for implementation and use of advancements in unstable slope instrumentation and monitoring by state departments of transportation over approximately the last decade.
The types of instrumentation and monitoring technologies range from devices installed on or in slopes to remote-sensing methods from ground, aerial, or satellite-based systems.Advances in Unstable Slope Instrumentation and Monitoring – TRB / NCHRP
