HEC-Commander Tools

HEC-Commander is William Katzenmeyer's notebook-based automation suite for the HEC stack: RAS-Commander notebooks for parallel batch execution of HEC-RAS unsteady plans (including across remote machines), HMS-Commander notebooks for calibration-parameter sweeps via Jython, and DSS-Commander for plotting results against gauges with calibration statistics. It is also a well-documented case study in AI-assisted engineering scripting, with conference material to match.

For pipeline-grade automation the newer ras-commander and hms-commander Python libraries (same author) are the cleaner dependency; the notebooks remain the fastest way to see the whole batch-run-and-calibrate workflow working end to end, and to adapt it interactively.
