parsing-hecras-geometry

Parses and modifies HEC-RAS plain text geometry files (.g##) using fixed-width FORTRAN format. Handles cross sections, storage areas, bridges, culverts, lateral structures, and Manning's n tables. Use when reading geometry files, modifying cross sections, updating roughness, extracting structure data, parsing .g## files, working with XS station-elevation data, or analyzing bridge/culvert geometry. Keywords: parse, geometry, .g##, cross section, XS, Manning's n, bridge, culvert, storage, fixed-width, lateral structure, inline weir, 2D land cover, bank stations.
