mizuRoute (in Japanese “mizu” means water) is a river routing model framework that can host various river routing methods that transport runoff output from a hydrologic model along the river network. The important modeling features are:

1. Conservative remapping of Hydrologic model runoff output to catchment defined by river network data.
2. Flexible in terms of river network types (gridded or vector), and time step.
3. Augmentation of river network topology soly based on donwstream reach information ensuing reach processing order.
4. River reach routing is performed per reach in the reach processing order no mater which routing procedure is used.
