Greetings:

We'd like to invite you to visit our new web site at
http://www.northcoast.com/~trpa

The site provides information on our software, River HABitat SIMulation
(RHABSIM), a program that greatly facilitates the analysis of impacts to
aquatic habitat resulting from changes in streamflow. RHABSIM is an
extensive conversion of the PHABSIM habitat simulation system developed
by the Instream Flow Group of the U.S. Fish and Wildlife Service for use
as a component of their Instream Flow Incremental Methodology (IFIM).

Ecologists, fisheries biologists, hydrologists and research scientists
will find RHABSIM of high value for simulating the effects of projects
modifying stream flow. When historical gage station data is available,
Time Series Flow and Habitat Duration analysis can provide habitat
change results compared to the historical flow regime.

The site contains extensive descriptions of the software, screen shots
of the program in use, links to professional associates and a form for
ordering or for asking questions.

For information on how RHABSIM can help to meet your needs please visit
the site, give us a call, or send email to mailto:[log in to unmask]


Thank you,

Thomas R. Payne
