RHABSIM
TESTIMONIALS:
"I was so pleased about RHABSIM because it reduces sensibly the time
necessary to build a physical habitat simulation model" - Paola
Annoni, Milan, Italy
"RHABSIM was obviously designed by a serious IFIM user to facilitate
PHABSIM assessments. The program brings a new era of ease of use to aquatic
habitat modeling" - Dr. Stacy Li, Loomis, California
"We are really pleased with RHABSIM. The program is working extremely
well and represents a major improvement over PHABSIM." - Barry
Nehring, Montrose, Colorado
"The graphical outputs of RHABSIM are exceptionally valuable to me as
an instructor...The toolbar scrolling by section, flow, HSI parameter or curve
set is an excellent enhancement to rapidly make comparisons. That aspect alone
will be a great teching tool, allowing students to make instant sensitivity
analysis comparisons. The top [plan] view of colour-coded cells for the entire
reach also illustrated variances between pools, riffles, runs and chutes in my
study reach...
"...an excellent job of developing...software into a functional
application not only for fisheries habitat management but for teaching instream
flow assessment methodologies as well. My only remaining regret is that I
didn't have RHABSIM six months ago when compiling my report..." -
Brian Meller, Lethbridge, Alberta
"When I began to use RHABSIM five years ago, I was pleasurably
surprised when discovering the existence of that useful tool that allowed an
easy PHABSIM simulation and an exhaustive IFIM analysis following all of its
phases. Since then, we use RHABSIM for IFIM instream flow studies, not only for
research but for teaching. RHABSIM is characterized by its simple, logical and
practical handling in all its modules. The excellent graphics and reports
facilitate the analysis and make of RHABSIM a great tool. What makes RHABSIM
unique is that their modules can satisfy the necessities for an expert in
hydraulics and a hydrologist (with HYDSIM and TIMESER, respectively) and for a
hydrobiologist (with HABSIM+TIMESER jointly). From the hydraulic point of view,
RHABSIM is really powerful and I am sure that it will satisfy the most
demanding hydraulic's necessities related with hydraulic simulations in stable
channels. I frequently also use exclusively RHABSIM to carry out hydraulic
simulations for steady flow in streams, obviating the rest of the modules. The
PHABSIM simulation with RHABSIM is very comfortable since those methods and
parameters are selected easily. The possibility to compare several simulations
simultaneously are a great improvement. And a very remarkable issue: RHABSIM is
the only program that I know that goes beyond a mere PHABSIM analysis and
completes all the phases of IFIM." - Juan Manuel Díez Hernández,
University of Valladolid, Spain (e-mail: jmdiez@iaf.uva.es).
"RHABSIM is a major facelift for PHABSIM II ... RHABSIM maintains the
logical flow and computations for hydraulic calibration and habitat suitability
models that are part of PHABSIM II. So what's new and different? The interface
with the user contains what we've come to expect from user-friendly software,
that is, pull-down menu bars, graphical output displays, and on-line help
menus...program enhancements make hydraulic simulation much simpler with
RHABSIM...RHABSIM makes it easier for users to graphically display their data,
edit entries, and locate errors without resorting to painful review of paper
outputs...
"I reviewed RHABSIM Version 1.17 for DOS...I approached the task with
considerable procrastination, well aware of the learning curve for the complex
series of modeling programs in PHABSIM. However, I was pleasantly surprised by
the programming design that made accomplishing routine tasks more pleasant...
"The screen format served as a wonderful reminder of where I was in the
modeling process--a must for anyone disturbed by frequent interruptions. The
menu bar provides access to drop-down menus and submenus. Process outlines are
a part of each main program module. These answer the "what do I do
next?" questions that plague all users...
"The experienced PHABSIM user will find that this program has a very short
learning curve. The variety of graphical displays were very useful during the
error-checking and model calibration phases...
"RHABSIM is a good tool that makes these modeling techniques easier to
learn. Existing PHABSIM users will find that the transition to RHABSIM is very
easy and well worth the switch. " - Donald J. Orth, Blacksburg,
Virginia
