Terrain2Flow is an open-channel hydraulics plugin for QGIS. It supports interactive DEM cross-section extraction, direction-aware longitudinal slope estimation, steady uniform-flow calculations using Manning's equation, rating-curve generation, bank-station and maximum-stage controls, NoData and monotonicity QA checks, and timestamped CSV/PNG/JSON engineering outputs. Requires NumPy and Matplotlib. Results are engineering calculation aids and should be independently reviewed before design or regulatory use.
