Supplemental Material for "Anomalous Shear Stress Variation in Wet Granular Medium: Implications for Landslide Lateral Faults"

Dataset and Constrained Parameters for "Anomalous Shear Stress Variation in Wet Granular Medium: Implications for Landslide Lateral Faults" by Chang et al. This dataset comprises 64 rheological experiments, which have been encapsulated in four experimental groups: Full Height, Half Height, Half Height & Load, and Ethanol-Water. The experiments were conducted using a double-cylinder geometry on three-phase granular media to simulate the lateral faults of slow-moving landslides. The dataset includes Mechanical Data for time-evolution measurements of shear stress, fluid volume fraction under varying conditions, and Image Data for velocity fields derived from PIV (Particle Image Velocimetry) analysis. In addition, it provides constrained parameters, such as steady-state shear stress and the characteristics of the flow structure. Article information: Chang, C., Ohno, K., Schulz, W.
