Geologic Characterization, Hydrologic Monitoring, And Soil-Water Relationships For Landslides In Kentucky, Matthew M. Crawford, L. Sebastian Bryson, Zhenming Wang, Edward W. Woolery

Report of Investigations--KGS

Complex spatial and temporal variables control the movement of water through colluvial soils in hillslopes. Some of the factors that influence soil-moisture fluctuation are soil type, thickness, porosity and permeability, and slope morphology. Landslide-characterization and field-monitoring techniques were part of a method to connect hydrologic and geotechnical data in order to monitor long-term hydrologic conditions in three active landslides in Kentucky, establish hydrologic relationships across the slope, and analyze specific soil-water relationships that can predict shear strength. Volumetric water content, water potential, and electrical conductivity were measured between October 2015 and February 2019. The duration and magnitude of drying and …
