Continental Water Dynamics
Atmospheric Data (NARR+NEXRAD)
Stream and River Flow Model
Land Surface - Atmosphere Model
(NOAH)

Last time we metRAPID coupled with SIM-France (atmospheric, land surface, groundwater model)
24,264 river reaches
10-year simulation
Streamflow Dam influenceBi-directional river/aquifer exchanges
Operational at MeteoFrance
cf. David and Habets (2009?), second manuscript in preparation
Transition to supercomputers
4
Desktop computer Lonestar
Transition to NHDPlus
5
Grid cell network of SIM-FranceBest available (1 km resolution)
GIS Mapped rivers
GIS-based river networks offer much better information than gridded
networks
6
Catchment shape file converted to a 900m grid of catchments
Coupling with Noah-UT (1)
Comid 1659595 1638214 …Inflow1 2.4 1.3 …Inflow 2 1.9 1.0 ……
Map of catchments
Runoff map
Runoff is spatially averaged for catchments surrounding NHDPlus flow lines
Coupling with Noah-UT (2)
Determination of wave celerities
15 min flow data
Cross lagged correlation

Conclusions
• Adaptation of RAPID on the Lonestar supercomputer
• Adaptation of RAPID to the NHDPlus framework • Coupling of RAPID with Noah-UT• Investigation of wave celerity• Run RAPID over Guadalupe and San Antonio
River Basins – Missing water in Victoria?– Need to fix time shift
