Use and interpretation. TWDB models support regional groundwater planning. They are not intended for local-scale or individual-site decisions. Consult the model report for calibration, assumptions and uncertainty. Download availability does not establish successful execution in MINT. Model outputs are not assumed to exist merely because an archive is downloadable. Simulation period, length/time units, vertical datum, and exact model footprint remain unverified unless a separately cataloged resource states them. Opaque model archives are not assigned mint_standard_variables. Variable bindings belong on separately extracted and scientifically interpreted resources. No standardized license was identified on the TWDB model download or model pages. Use is subject to TWDB terms and the model documentation; verify rights before redistribution.
