Method synopsis

Installation of three 10-meter deep monitoring wells along a hillslope transect equipped with suction lysimeters, pressure transducers, and temperature sensors for long-term subsurface monitoring. Wells enable collection of pore water samples and continuous measurement of water table fluctuations.

Synthesized from method descriptions across 14 papers using this protocol.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Aerobic respiration controls on shale weathering (2023), Geochimica et Cosmochimica Acta. The protocol was originally introduced by Depth- and time-resolved distributions of snowmelt-driven hillslope subsurface flow and transport and their contributions to surface waters. (2019), Water Resources Research. Implementations in other papers (listed below) may differ.

1. Install monitoring wells
   Three observation wells (PLM1, PLM2, PLM3) were drilled to a depth of 10 m using a track-mounted drill rig with a 0.12 m (4.75 in.) diameter ODEX drilling bit. Wells were equipped with suction lysimeters to carry-out vertically-discrete pore water sampling, pressure transducers to perform daily-measurements of the water table (AquaTROLL 200, exact PLM2 where the water table was determined from equilibrium pressure and moisture measurements), and temperature sensors.
   Quantities: 3 wells, 10 m depth each, 0.12 m diameter, wells separated by ~70 m from each otherDuration: Installation occurred in 2016Conditions: Located along a 140 m long hillslope transect with average slope of 19%, exposed northeast and drains into an adjacent floodplain
   Equipment: track-mounted drill rig, ODEX drilling bit, suction lysimeters, pressure transducers, AquaTROLL 200, temperature sensors
