Data supporting: Nonstationary Behavior of Resistivity–Moisture Relationships in Time-Lapse ERT Monitoring of Sandy Soils

This dataset contains processed data supporting the figures and results presented in the manuscript: "Nonstationary Behavior of Resistivity–Moisture Relationships in Time-Lapse ERT Monitoring of Sandy Soils". The dataset includes: - Processed electrical resistivity tomography (ERT) data (e.g., Δlogρ) used to generate spatial profiles and temporal analyses - Soil moisture time series from in situ sensors - Rainfall data associated with selected recharge events - Event-based summaries and derived quantities used in the analysis (e.g., inferred water-content changes) All data are provided in a format suitable for reproducing the figures and key results of the study. Raw ERT data and inversion outputs are not included in this dataset but are available from the corresponding author upon reasonable request.
