Data and code supporting "A Thin-Layer Reduced-Order Closure for Interpreting Capillary-Fringe Effects in Finite-Element Seepage Analysis of Earthen Dams"

This repository contains the computational reproducibility materials supporting the manuscript “A Thin-Layer Reduced-Order Closure for Interpreting Capillary-Fringe Effects in Finite-Element Seepage Analysis of Earthen Dams.” The archived materials include the Python implementation of the thin-layer hydraulic closure, numerical quadrature and truncation-verification scripts, five independently executable figure-generation scripts, derived parameter records, and numerical certification documentation. The implementation reproduces the effective hydraulic thickness, diagnostic compression ratio, finite-integral truncation quantities, sensitivity calculations, and manuscript figures reported in the study. Published finite-element results used as benchmark inputs are taken from the studies cited in the manuscript; original third-party finite-element source files and copyrighted source publications are not included in this deposit. No new laboratory or field measurements were collected for this study. Documentation and derived research materials are released under the Creative Commons Attribution 4.0 International licence, and the Python source code is released under the MIT License. reduced-order modellingunsaturated seepagefinite-element methodvan Genuchten-Mualemcapillary fringehydraulic resistancediagnostic inversionearthen damsgeotechnical engineeringreproducible research
