Landslide Soil Hydrology Data for Three Landslides in Kentucky

This data is from three landslides monitored in Kentucky between October 2015 and September 2020. The purpose was to capture and analyze subsurface hydrologic conditions within the landslides at different slope positions over time. The site descriptions, field methodology, data-acquisition techniques, and observations provide a general picture of soil moisture in hillslope soils. Data collected includes volumetric water content, soil water potential, bulk electrical conductivity, bulk dielectric permittivity, temperature. Water potential is the energy state of water in the soil, a determination of stress in the soil based on how water moves. Water potential can be described as the negative pore pressures exerted by the soil matrix that determine water flow in unsaturated soil. Rainfall was measured at each landslide with a tipping-bucket gage and a data logger. Rainfall collection was standalone, and not connected to the system collecting the soil-moisture data. Rainfall data provided here is in inches. The field instrumentation and implementation are cost-effective techniques that can be used for subsequent projects such as slope-stability assessment and landslide-susceptibility modeling.
