HAP v5.11 runs within the HEC-HMS user interface or in headless mode (no GUI). It is built on:
is a legacy but capable scripting interface for HEC-HMS v5.1.x, offering powerful automation for hydrologic modeling. It enables batch runs, calibration, sensitivity studies, and custom reporting using Jython. However, for new projects, users should consider migrating to HMS-Py (Python 3) available in HEC-HMS v5.3 and later, which provides modern library support, better performance, and long-term maintainability.
