Manual for the reproducible geometric and computational implementation of Bührig-type metrics in submarine canyons

This record documents the existence of a technical and methodological manual that formally supports the software “Bührig Metrics Reproducible Pipeline” (Viveros Velásquez, M. A., 2026), a reproducible computational pipeline for the calculation of Bührig-type transverse metrics in submarine canyons. The software source code and version control are publicly available through a dedicated GitHub repository. This manual provides the detailed technical documentation associated with that repository. The manual explicitly describes the geometric definitions, methodological decisions, and computational procedures implemented in the pipeline, which are required for the correct interpretation, reproduction, and scientific use of the metrics derived from real profiles extracted from bathymetric digital elevation models. This document does not present new scientific results nor evaluate geomorphological hypotheses. Its purpose is to serve as an auditable technical reference that ensures geometric traceability, methodological reproducibility, and consistency between input data, geometric construction, and final metrics. The file associated with this record is under restricted access. The complete documentation is available upon request or under license agreement.
