This data file contains three worksheets containing raw data and descriptive statistics regarding roughness (amplitude, spatial, and hybrid) parameters obtained in the longitudinal direction of the sp
Abstract Roughness is a fundamental feature to define rock deformability and resistance. A detailed characterization of discontinuity surface geometry is essential for understanding some of the rock’s
The dataset is the 3D rock joint surface database mentioned in the manuscript, which are point cloud files of 310 samples stored in Stanford Triangle Format (*.ply). All samples are processed into sta
Direct numerical simulation (DNSs) are used to systematically investigate applicability of minimal channel approach for characterization of roughness-induced drag in irregular rough surfaces. Roughnes
