MODFLOWP

Parameter-Estimation Version of the Modular Model (obsolete program--superseded by MODFLOW-2000 and UCODE-2005)

Information

• Summary of MODFLOWP
• Version history
• UNIX or DOS installation instructions (README file)
• How to obtain U.S. Geological Survey printed documentation
• How to register to receive software update and enhancement notices

Software

Selection of the following options preceded by a binary icon retrieves a compressed UNIX tar file or a self-extracting DOS executable. A README file containing installation instructions is included with each of the software distribution files. There are separate README files for the UNIX and DOS distributions.

The Free Software Foundation's gunzip is necessary to uncompress the UNIX tar files available below. However, some World Wide Web browsers automatically uncompress retrieved files. Thus, running gunzip as stated in the installation instructions may be unnecessary.
