Landslide Monitoring and Characterization – Meadowview Landslide – Boyd County

The KGS is currently conducting a landslide monitoring project on a landslide in Boyd County. General goals of the project include determination of depth and shape of the sliding mass, determination of direction and velocity of sliding, monitoring groundwater conditions, collecting rainfall data, obtaining geotechnical soil properties, and measuring electrical resistivity of the slide material. The subsurface part of the investigation includes the installation of six boreholes, two for slope inclinometer measurements, two for piezometers to monitor groundwater conditions, and two for downhole electrical resistivity measurements.

A key aspect of this project is to determine a correlation between geotechnical properties and geophysical measurements. This multi-disciplinary approach can be used to address slope stability, resolve mechanisms of slope failure, and identify areas susceptible to landslides. This study has the potential to act as a framework for landslide hazard assessment, landslide susceptibility modeling, determining risk, and prevent future losses in Kentucky.
