Question 2: Does your agency have unstable slopes such as embankments, cut slopes, and beyond-the-right-of-way slope hazard sites that exhibit movement or a threat of movement? Question 3: Does your agency use any form of geotechnical instrumentation and monitoring for unstable slopes other than routine or incidental observation? Question 4: How are unstable slopes selected for instrumentation and monitoring?

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.
