parsing-hecras-geometry

Parsing HEC-RAS geometry files reads fixed-width FORTRAN-formatted .g## data to extract and edit cross sections, roughness tables, and structure data. This Skill automates that process, handling bank stations, 450-point limits, and backup generation through a modular API without manual file editing.

Yes. This Skill modifies roughness (Manning's n) tables and cross-section station-elevation data directly, with automatic bank interpolation on write and backup creation to prevent data loss.

You can extract and work with bridges, culverts, storage areas, lateral structures, and inline weirs. The Skill parses structure data from fixed-width geometry files and supports modifications through its modular accessor and writer APIs.

Yes. The Skill enforces HEC-RAS's 450-point cross-section limit and handles case-sensitive identifiers, bank-station logic, and automatic interpolation to comply with model constraints.

Load the geometry file (e.g., model.g01) using the Skill's parser to list cross sections and access their station-elevation data. The modular API returns structured geometry data for analysis or modification.

HEC-RAS geometry files use fixed-width FORTRAN format (.g## files). This Skill reads and writes that format, respecting column positions and case sensitivity required by HEC-RAS models.
