RHABSIM Version 3.0

RHABSIM (Riverine HABitat SIMuation) is a fully integrated program for river hydraulics and aquatic habitat modeling using the Instream Flow Incremental Methodology (IFIM). Running in Microsoft Windows and DOS, it is an extensive conversion of the PHABSIM hydraulic and habitat simulation system developed by the U. S. Fish and Wildlife Service.

UPDATE

All previous versions of RHABSIM are now FREE from Thomas R. Payne & Associates and can be considered public domain software.  Version 3.0 (also available FREE) contains partial fixes for some Windows XP and 2000 compatibility issues (screen sizing and font display drivers) and the program is fully functional.  However, since even RHABSIM 3.0 can be inconvenient to use at times, we are allowing open use until a new version is completed.

UPDATE 08/15/2013

Thomas Payne has collaborated with Ian Jowett and Bob Milhous to create new, comprehensive software that “implements the substance of the IFIM”.  SEFA, System for Environmental Flow Analysis, is available on a new website http://sefa.co.nz/.

FREQUENTLY ASKED QUESTIONS

I need to run a Time Series Flow and Habitat Duration analysis. I have Weighted Usable Area results from a PHABSIM run, but I don't have streamflow data for the river in question. Can RHABSIM import data from the U.S.G.S?

If you are currently a RHABSIM user and have questions about installing and running the programs, see our troubleshooting page.
