Description

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.

Supporting Information

Two types of sensors were used to capture the subsurface hydrologic conditions within the landslides. The first was a water-content reflectometer (CS650), which is a multiparameter sensor that monitors the soil’s volumetric water content, bulk electrical conductivity, bulk dielectric permittivity, and temperature. The other sensor (MPS-6) used was a dielectric water-potential sensor for measuring soil-water potential. Rainfall was measured at each landslide with a tipping-bucket gage and a data logger. The battery-operated logger has a 1-min resolution, and rainfall was logged at 0.25 mm/tip. Rainfall collection was standalone, and not connected to the system collecting the soil-moisture data. Rainfall data provided here is in inches. See publication listed below for additional instrumentation and software information.

Notes

Some of the data is missing for various reasons, primarily sensor malfunction and/or data collection program change. The rain gage occasionally became clogged or needed a battery change. If rainfall data was not accurately collected, daily amounts were taken from the nearby Kentucky Mesonet http://www.kymesonet.org/index.html

NAN = not a number

-7999 = sensor malfunction related to sensor detection limit
