Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Dwindling Groundwater Reserves Will Threaten Mountain Streamflow in a Warmer World (2023), Research Square. Implementations in other papers (listed below) may differ.

1. Develop three-dimensional geologic model
   Created geologic model using Seequent's 3D Leapfrog geological modeling software based on USGS maps at 1:24k and 1:250k scales. Eight geologic units were included divided into six layers using terrain-following grid approach with constant thickness for total thickness of 400 m. Structural discs were assigned to boundaries where strike and dip information was observed and fit to published cross-sections.
   Quantities: 8 geologic units, 6 model layers, 400 m total depth, 1:24k and 1:250k scale mapsDuration: Not specifiedConditions: Based on existing geological survey maps and cross-sections
   Equipment: Seequent's 3D Leapfrog geological modeling software
