Gulf Setup Docs from Claude Prompt run on November 18, 2025 "Can the GULF groundwater model from the USGS be run on a linux environment?"

Initial Response: The GULF groundwater model can definitely be run on a Linux environment! The GULF (Gulf Coast Lan USGSd Subsidence and Groundwater-Flow) model is built using MODFLOW 6, and MODFLOW 6 binaries are distributed for Windows, Mac, and Linux operating systems GitHub. Here are your options for running it on Linux: 1. Pre-compiled binaries (easiest option) MODFLOW 6 distributions are built on Ubuntu 20.04 for broader compatibility across Linux distributions GitHub. You can download these from the MODFLOW-ORG/executables repository on GitHub. 2. Using FloPy's get-modflow utility FloPy includes a get-modflow utility that can install USGS MODFLOW and related programs for Linux Readthedocs. This is convenient if you're already working with Python and FloPy for model setup and analysis. 3. Compile from source MODFLOW 6 is written in FORTRAN and can be compiled on Linux using compilers like GFORTRAN Simonwenkel, making it easily deployable on high-performance computing clusters. For the GULF model specifically: You can download the model files from the Texas Water Development Board's GAM files download page Texas Water Development Board. Once you have MODFLOW 6 installed on your Linux system, you should be able to run the GULF model files directly since it's a standard MODFLOW 6 model.

created a complete environment setup package for running the GULF groundwater model on TACC systems. Here's what I've built for you: 📦 Package Contents Core Files

setup_gulf_environment.sh (12 KB)

Automated installation script for TACC systems Handles everything: Python environment, MODFLOW 6, all dependencies Supports all TACC systems (Frontera, Stampede3, Lonestar6)

gulf_environment.yml (781 B)

Conda environment specification Defines all required packages with versions Ensures reproducible environment

requirements.txt (1 KB)

Pip-based alternative for package installation Useful if you prefer pip over conda

GULF_Model_TACC_Notebook.ipynb (14 KB)

Ready-to-use Jupyter notebook template Complete workflow: verify → load → run → visualize Includes documentation and examples

Documentation

README_GULF_SETUP.md (8.7 KB)

Comprehensive documentation TACC-specific instructions Troubleshooting guide Batch job examples

QUICK_START.md (5.3 KB)

3-step installation guide Quick reference for common tasks Key features and notes

🚀 Quick Start (3 Commands) bash# 1. Make executable chmod +x setup_gulf_environment.sh

2. Run setup with Jupyter support

bash setup_gulf_environment.sh --jupyter

3. Activate and verify

source ~/gulf_model_env/activate_gulf.sh python ~/gulf_model_env/verify_environment.py ✨ Key Features

✅ TACC-Optimized: Works on Frontera, Stampede3, and Lonestar6 ✅ MODFLOW 6.2.1: Automatically installs the exact version required by GULF model ✅ Complete Python Stack: FloPy, PyEmu, GeoPandas, and all dependencies ✅ Jupyter Integration: Includes custom kernel for notebooks ✅ Verification Script: Automatically checks installation ✅ Isolated Environment: Won't interfere with other projects ✅ Batch Job Ready: Includes SLURM script examples

What Gets Installed From the GULF model README, I identified these requirements:

Python 3.10 MODFLOW 6 (v6.2.1 specifically) FloPy (≥3.3.6) - MODFLOW Python interface PyEmu (≥1.2.0) - PEST++ interface spnspecs - USGS publishing standards Scientific stack: NumPy, Pandas, Matplotlib, SciPy Geospatial: GeoPandas, Shapely, Fiona, Rasterio Jupyter Lab for interactive work

For Your SUBSIDE and Other Projects This setup will also work great for your SUBSIDE subsidence monitoring work since it:

Includes all geospatial analysis tools (GeoPandas, etc.) Sets up MODFLOW 6 for any groundwater modeling Provides Jupyter integration for interactive analysis Works on TACC where you can leverage HPC resources

The scripts are flexible - you can customize the installation directory, skip components, or adjust for different projects!Setup gulf environmentSH DownloadGulf environmentYML DownloadRequirementsTXT DownloadGulf model tacc notebookIPYNB DownloadReadme gulf setupDocument · MD DownloadQuick startDocument · MD DownloadDownload allRetryClaude can make mistakes.
