USGS WATER RESOURCES APPLICATIONS SOFTWARE NOW ON THE WEB
A suite of 48 software packages and related materials, used by the U.S.
Geological Survey for hydrologic analysis and modeling, is now available for
electronic retrieval through an on-line repository on the World Wide Web.
The repository is accessible via the WWW from the USGS Water Resources Home
Page at:
http://h2o.usgs.gov/
by selecting the announcement for "USGS Water Resources Applications
Software" or directly at:
http://h2o.usgs.gov/software/
In addition, the repository is available via anonymous File Transfer
Protocol (FTP) from the USGS Water Resources Information server:
h2o.usgs.gov or 130.11.50.175 (path: pub/software)
Note: a mirror site (http://www.geogr.uni-jena.de/software/) is available
at Friedrich-Schiller University, Department of Geoinformatics, Jena,
Germany that some users may find more convenient. FTP access is also
available at www.geogr.uni-jena.de (path: pub/software).
Each software distribution package consists of compiled or source code,
test data sets and documentation files. All of the USGS water resources
hydrologic analysis and modeling software applications available publicly on
the WWW are documented by published USGS reports. The software distribution
packages have been prepared primarily for the Data General AViiON DG/UX
platform and for compilation on other UNIX-based computers. The USGS
continues to prepare software packages for its own use on UNIX-based and
other computer platforms such as DOS-based personal computers. As these
packages are available, they will be added to the repository.
The software available in the repository is grouped into the following
categories: geochemical, ground water, surface water, water quality and
general. Examples of the software now available through the on-line
repository include:
PHREEQC--A program for aqueous geochemical calculations;
MOC--Two-dimensional method of characteristics ground-water flow and
transport model;
MODFLOW--A modular three-dimensional finite-difference ground-water flow
model;
SUTRA--Saturated and/or unsaturated, constant or variable-density fluid
flow, and solute or energy transport (two-dimensional finite
element code);
ANNIE--Interactive hydrologic (time series) data management;
BRANCH--Branch-network one-dimensional dynamic flow model;
HSPEXP--Expert system for calibration of the Hydrological Simulation
Program--Fortran (HSPF).
Since June 1996, when these programs and associated documentation became
publicly available on the WWW, the number of accesses by users outside the
USGS has increased rapidly. Currently, the site is "visited" about 2500
times per month by users outside the USGS.
