Introduction

The purpose of these web pages is to provide a unified description of the formats for  MODFLOW-2005 input files.  These descriptions have been copied from the original reports in which they were published and supplemented with materials found in the "doc" directory of the  MODFLOW-2005 distribution file. These web pages are not substitute for or a definitive guide to  MODFLOW-2005.  They may contain errors that are not in the original documents.  In case of doubt, consult the original documents or examine the source code.

In a few cases, obvious typographical errors in the original documents have been corrected in the version of the input instructions presented on these web pages.  Such changes are not marked.

Some packages, such as the Interbed Storage package, were originally published as part of MODFLOW-88.  In such cases, the instructions for including these package in a  MODFLOW-2005 model have been updated to reflect how the input is specified in  MODFLOW-2005.

In a few cases, the instructions have been supplemented by additional material not found in the original input instructions.  Such materials are shown in a different type face like this.  The sources of such additional material include examination of the source code, correspondence with the authors of a package, and experience.

Keywords in the input files that must be entered exactly as shown (in a case-insensitive manner) are displayed in these web pages in bold and italics like this.

Please send comments and corrections to Richard B. Winston (rbwinst@usgs.gov).
