hydraulic properties that used to compute celerity and diffusivity (for DW routing) use uniform flow equation (i.e., manning equation).
Adding options to include floodplain for each reach. This requires bankfull depth, floodplain slope (default is 1% slope extending from river bank).
This is similar approach to CaMAFlood, or HyMAT type floodplain mechanism. This does not intend to do HEC-RAS type channel geometry definition (with many channel cross sections information) that kills run for high resolution river network like MERIT hydro over global, due to memory and much high intense computation.
floodplain is not implemented to IRF (no concept of channel geometry) and KWT (seemingly more complex) at least for now
