Scale-Dependent Spatial Support of CPT/CPTu-Derived Stratigraphic Boundaries — Georisk Reproducibility Package
Year: 2026
Type: other
Abstract: This OSF project provides the reproducibility and research-object package supporting the manuscript “Scale-Dependent Spatial Support of CPT/CPTu-Derived Stratigraphic Boundaries: A Null-Benchmarked Framework for Risk-Informed Regional Site Characterisation.” The study develops a scale-dependent framework for evaluating cross-profile spatial support of CPT/CPTu-derived stratigraphic boundary candidates using data derived from the Dutch Basisregistratie Ondergrond (BRO) archive. The final analytical catalogue contains 913 boundary candidates from 160 boundary-bearing profiles, of which 900 are evaluable for the revised Regional Boundary Support Index (RBSI) and Radius Sensitivity Index (RSI). The repository contains analysis-ready research objects, canonical analysis scripts, configuration and environment records, count-controlled permutation outputs, cluster-aware bootstrap results, sensitivity and robustness analyses, figure and table source data, supplementary materials, provenance records, licensing documentation, and SHA-256 integrity manifests. The primary inferential benchmark uses 1,000 boundary-count-stratified whole-profile spatial permutations. Results show clear above-null spatial support at 2.5 and 5 km, a modest and geographically heterogeneous signal at 10 km, and no population-level exceedance of the primary permutation null at 25 or 50 km. RBSI is a relative spatial-support index and must not be interpreted as a probability of geological correctness, engineering reliability, or failure. The reviewed 35-profile/188-boundary subset is retained as an internal reference and robustness layer and is not presented as independent geological validation. Post-hoc sensitivity and consistency analyses are explicitly distinguished from the controlling primary analysis. Raw externally maintained BRO/PDOK data and third-party source material are not redistributed where redistribution or relicensing rights are not established. Source identities, access information, provenance, and reconstruction procedures are provided where appropriate. This repository is intended to support transparent audit, reproducibility, and reuse of the analytical workflow within the stated scientific and licensing boundaries.
