OFFICE OF GROUND WATER TECHNICAL MEMORANDUM 94.05

Subject: Report, "Summary of selected computer programs
         produced by the U.S. Geological Survey for simulation
         of ground-water flow and quality," Circular 1104

The attached subject report by Charles A. Appel and Thomas E.
Reilly provides information on selected computer programs used
for problems involving:  saturated flow, variably saturated
flow, solute transport (saturated and variably saturated),
solute and heat transport (saturated), freshwater/saltwater
flow, heat transport, solute or heat transport (saturated and
unsaturated), aquifer management, chemical mass balance, aqueous
speciation, and chemical mass transfer.



The information given for each computer program includes the
reference, a brief description of the field conditions that the
program can simulate, the numerical approximations used, an
indication of the extent of past field applications of the
program by USGS personnel, and where to obtain copies of the
report, and in some cases, the computer code.

In addition to the use of this compilation of selected computer
programs to personnel in the Water Resources Division, it also
will be useful in responding to requests from outside of the
Water Resources Division for information on USGS computer
programs available to the public.

We advise that this report be distributed to technical and
management personnel concerned with ground-water flow and
quality.
