Libraries¶
-
The flagship Python library for automating HEC-RAS — 50+ modules spanning plan execution, HDF results extraction, geometry parsing, QA/QC, USGS integration, and remote distributed compute. The most robust and powerful way to use the library.
-
The full companion library for automating HEC-HMS — basin/met/control models, runs, DSS, results analysis, Atlas-14 storms, and cloud-native export.
-
Full-project archival and cloud-native GIS export for HEC-RAS and HEC-HMS — GeoParquet, PMTiles, DuckDB, PostGIS, terrain, results, and web-map delivery.
Tools¶
These expose a focused subset of capabilities. For the most complete and powerful workflow, reach for the ras-commander library directly.
-
A Model Context Protocol server that lets Claude and other LLMs query HEC-RAS projects through a curated subset of ras-commander.
-
Hydrology / Arc Hydro helper tools built on ras-commander.
-
A QGIS plugin surfacing a subset of ras-commander inside the QGIS GUI.
