THOR - the rock strength database

Newest version avaliable at 10.5281/zenodo.12687444 Thor is an extensive and (nearly) exhaustive rock strength compilation based on publications from 1980 - 2024 (Scopus). Data reported in Thor includes: Search tool and watershed erodibility calculator: A Microsoft Excel®-based tool that enables users to select specific lithologies and generate summary statistics. This tool also calculates watershed erodibility by accounting for lithologies and their respective proportions in a watershed. RN - rebound values (all converted to Schmidt Hammer model N), grouped by lithology. σUCS - uniaxial compressive strength (σUCS), grouped by lithology. LE - lithologic erodibility index (LE), grouped by lithology (also referred to as Klp in this database). Authors list - a list of all publications/references used in this compilation.
