RAPID v1.2.0

David, Cédric H.


The Routing Application for Parallel computatIon of Discharge (RAPID) is a river network routing model. Given surface and groundwater inflow to rivers, this model can compute flow and volume of water everywhere in river networks made out of many thousands of reaches.

For further information on RAPID including peer-reviewed publications, a manual,sample input/output data, sample processing scripts and animations of model results, please go to:

This version v1.2.0 was used to produce the simulations that supported the writing of:
