Model Code Name:
PARFLOW  

Description:
ParFlow is an open-source, object-oriented, parallel watershed flow model. It includes fully-integrated overland flow, the ability to simulate complex topography, geology and heterogeneity and coupled land-surface processes including the land-energy budget, biogeochemistry and snow (via CLM). It is multi-platform and runs with a common I/O structure from laptop to supercomputer. ParFlow is the result of a long, multi-institutional development history and is now a collaborative effort primarily between CSM, F-Z Jülich and UniBonn. ParFlow has been coupled to the mesoscale, meteorological code ARPS, the NCAR code WRF and the German Weather Service model COSMO
