RAPID v1.8.0

Cedric H. David


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.

This version v1.8.0 was used to produce the simulations that supported the writing of:
