Install
pip install rashdfAbout rashdf
rashdf, developed under FEMA's Future of Flood Risk Data programme, reads the HDF5 files HEC-RAS 6.x writes — geometry, plan and results — and returns them as GeoDataFrames and xarray objects: mesh cells and faces, water-surface time series, reference lines and points, all queryable without opening RAS.
It deliberately does one layer of the stack (read access, done well) which makes it a solid foundation for stochastic pipelines, dashboarding and post-processing at scale. If you only need results out of RAS — not runs launched — rashdf is the cleanest dependency to take.
