FOLLOW THE METHOD
A reason behind every step.
Calculate the geotechnical Factor of Safety (FS) against translational shallow landsliding across colluvial hillslopes using the limit equilibrium Mohr-Coulomb equation. Standardized parameter settings: 15.0, 20.0, 25.0, 30.0, 35.0, 40.0 degrees.
Sensor Calibration & Zero Benchmark Verification: Inspect all hydrographic, meteorological, or optical sensors. Verify calibration against certified reference instruments and establish digital zero tare.
Field Site Setup & Geodetic Survey Benchmark Alignment: Deploy the measurement rig across the designated landscape transect or flume channel. Align survey axes with local geodetic benchmarks and leveling datum.
Initial Gauge Alignment & Parameter Setpoint Selection: Position the sensor array at the target sampling station. Select the initial hillslope angle β setpoint and confirm steady-state baseline readings.
Systematic Parameter Variation & Acquisition: Increment the hillslope angle β systematically across the designated domain (15.0 to 40.0 degrees), permitting full hydrodynamic or atmospheric stabilization at each step.
Multi-Sensor Telemetry Recording & Signal Integration: Record the primary dependent variable (Geotechnical Limit Equilibrium Factor of Safety FS) alongside auxiliary meteorological and channel parameters. Verify signal stability and repeatability.
Post-Survey Verification & Data Archive Export: Check sensors against the baseline benchmark to verify absence of post-run drift, secure all field equipment, and export digital observations to the persistent geospatial database.
