Crate hydra_engine_och 

hydra-engine-och — Hydra’s open-channel hydraulics simulation engine.

Early scaffold. This crate is the future home of Hydra’s open-channel hydraulics simulation engine, operating on the HEC-RAS domain the way hydra-engine-wds operates on the EPANET data model. No simulation capability is implemented yet; the crate is published so its name and versioning track the Hydra workspace from the start. Development happens at https://github.com/neeraip/hydra.
