UCODE

A computer code for universal inverse modeling

Information

UCODE is a universal inverse modeling program (DOS & UNIX) developed as a collaborative project between the U.S. Geological Survey and the International Ground Water Modeling Center at the Colorado School of Mines in cooperation with the U.S. Army Corps of Engineers Waterways Experiment Station.

Documentation published by the U.S. Geological Survey on UCODE and on model calibration is available below for electronic retrieval. Alternatively, printed copies of the reports or of any other USGS report can be ordered for delivery by mail.

Software

At present, the UCODE software is maintained by and is available from the International Ground Water Modeling Center. Questions on the installation and use of UCODE should be directed to the International Ground Water Modeling Center contact listed below rather than to the U.S. Geological Survey.
