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 between CSM, F-Z Jülich, UniBonn, LLNL, WSU, LBL, and LTHE. ParFlow has been coupled to the mesoscale, meteorological code ARPS, the NCAR code WRF and the German Weather Service model COSMO.
ParFlow Web Page
To get started with ParFlow, I would recommend the manual. It contains lots of useful information on getting started, a complete table of published studies that have used ParFlow for a range of applications, some very helpful annotated examples to get new users started and a complete library of the keys for running simulations and tools for postprocessing output. If you are building a model of a real domain there are helpful blogposts on a workflow for setting up and spinning up models on the ParFlow Blog. Also the blog contains posts on trouble shooting slow model performance and common errors when starting a simulation that will be useful to new users. Finally, the blog contains a lot of useful advice on getting ParFlow compiled on many different platforms.
A complete publication list for all ParFlow references now appears in the manual. However, good publications related to the development of ParFlow are AF1996, JW2001, MM2005, KM2006, KM2008, MK2008a, M2013; a publication related to ParFlow coupled to ARPS (PF.ARPS) is MCK2007 a publication related to PF-WRF is MLMSWT2011 and ParFlow coupled to COSMO SMSKS14.
ParFlow Version 3.3.1
ParFlow is released under the GNU LPGL license agreement.
ParFlow is now on GitHub. The current release is linked below, we recommend starting there. The project may be accessed here.
