The Simple River engine reads data from three input files, which contain information about the inflow to the river nodes (boundary file), the simulation period and timestep length (simulation file) and the river network (network file) - see Figure 2.

Planning the migration
Before you start migrating a model it is important that you have a precise idea about how your model is intended to be used when it is running as an OpenMI component. Think about any situation where it will be useful to run your model linked to other OpenMI components. Such components could be other models, data providers, optimization tools or calibration tools. You may even find it useful to run two instances of your model component in the same configuration.
This chapter suggests ways in which you can plan the migration of a model, including thedevelopment of use cases and the definition of exchange items.
