WinHumicV for Win95/98/NT
WinHumicV is based on the Humic Ion-Binding
Model V, originally created by Dr. Edward Tipping of the Institute
of Freshwater Ecology, UK, in 1992 (Tipping and Hurley, 1992). WinHumicV
combines Model V with inorganic ion speciation, models for Al
and Fe oxide precipitation, cation exchange to clay minerals, and
adsorption-desorption reactions of fulvic acid. WinHumicV is
related to the previously published WHAM code (Tipping, 1994)
but there are a few differences, the most important being that WinHumicV
is written in Visual Basic and adapted for the Windows environment. The
purpose of WinHumicV is to calculate equilibrium chemical
speciation in surface and groundwaters, sediments and soils, in which the
speciation and solubility of cations are determined by organic matter
can be run in two modes, one for aqueous speciation problems, and one for
problems in which sorption to particles (such as sediments or soils) is
also considered; the latter mode is chosen by default once the user starts
may download and use WinHumicV, on the following conditions:
- Please register as
a user by sending an e-mail to me (Jon Petter Gustafsson).
- Do not
redistribute any parts of the software to others without contacting me
- If you decide to
publish any results obtained by this software, make sure to include these references.
aim of WinHumicV is to make the powerful features of Model
V more easily accessible for researchers in soil and aquatic
chemistry. WinHumicV includes the following features:
- You may run
several (up to 20) problems at once, by using the Multi-problem /
- The pH can either
be fixed, or calculated from the charge balance.
- You may include a
heterogeneous site affinity distribution for bidentate metal-humic
- Presentation of
results from WinHumicV runs on separate output tables; export of
results to Excel
- Easy management of
WinHumicV's thermodynamic database from within the program
- The interface was written with Visual Basic
5.0, professional edition.
- You will need Windows 95 or NT 4.0 or higher
to run this program.
- Since WinHumicV interfaces with Excel, it is
desirable that you have Excel 5 or higher installed on your computer.
- The program will NOT fit on your
screen if the resolution is 640 x 480 or lower.
- I do not take any responsibility for
possible problems that arise because of the installation of this
program. However, I would be grateful if problems and bugs are
reported to me; this will benefit future users of this program.
- The program can read input files created by
Tipping's WHAM-S code.

The setup package,
whuvsetup.zip, contains the executable WinHumicV program and all
When you have
downloaded the files, you will have to unzip them using WinZip or PKUNZIP.
whuvsetup.zip file includes the WinHumicV setup program, Setup.exe. If you
have a recent version of WinZip, Setup can be initiated directly. Otherwise
you should double-click the Setup.exe icon when all files have been
unzipped. Setup will install:
- The executable WinHumicV program, entitled 'WinHumicV.exe'. The file will
be placed in the directory "c:\WinHumicV".
- The thermodynamic database. Included in the package is Ssed10.dbs
which is also the original database for WHAM (Tipping,
- Help file system in HTML format. Open the file "whumvhlp.htm"
to access the help files.
- Some Windows system files,
necessary for the program to run. Make sure they are installed
correctly in your Windows system directory.
- Five sample files.
After installation, use Windows Explorer to create a shortcut to
"C:\WinHumicV\WinHumicV.exe" and copy it to your desktop.

code were made to increase execution speed. Selected sweep parameters are
now saved to the input and output files and therefore they do not need to
be edited every time the user opens a new file.
