Sample RAPID input/output data
Download all input and output data from David et al. (2011, JHM). These include NHDPlus river network connectivity, lateral inflow from the land surface (computed with Noah-MP) and gage measurements (from USGS NWIS) for a 4-year run (between 2004-01-01 and 2007-12- 30) in the San Antonio and Guadalupe River Basins in Texas. 10.5281/zenodo.16565
Download all input and output data from David et al. (2011, HP). These include SIM-France river network connectivity, inflow from the land surface (computed with ISBA), bilateral inflow from groundwater (computed with MODCOU) for a 10-year run (between 1995- 08-01 and 2005-07-31) in the domain of SIM-France.

Some RAPID scripts
Download a script to get NLDAS2 land model data and convert them to RAPID water inputs, and download other corresponding RAPID input data.
Download an NCL script to make flow maps from a shapefile and corresponding RAPID outputs and saved as an image. The images created with this script are used to make the animations in this website.
Download a Fortran script to process USGS NWIS observations obtained with CUAHSI HydroDesktop for RAPID.
Download a Python script to download USGS NWIS observations from the CUAHSI WaterOneFlow webservices.
