THOR - the rock strength database

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.
