PATH3D

PATH3D V4.6 is a powerful and widely used particle-tracking program for MODFLOW.

A Groundwater and Travel-Time Simulator

PATH3D can be applied to help visualize three-dimensional flow fields, to delineate contaminant capture zones or wellhead protection zones, and to evaluate the effectiveness of groundwater remedial scenarios under complex hydrogeological conditions. PATH3D is a valuable extension to a groundwater flow model, and is frequently a practical alternative to a contaminant transport model.

Please Note: Path3D has been deprecated and is no longer actively maintained by SSP&A.  Users running Path3D on newer versions of Windows may experience user interface related problems. Current and future development of this software functionality has migrated to mod-PATH3DU which incorporates the capabilities of MODPATH, Path3D, and additional capabilities beyond those of these programs.

Key Features

• Full compatibility with MODFLOW88 and MODFLOW96
  PATH3D is designed to function directly with earlier versions of MODFLOW, the industry-standard groundwater flow code.
  ( PATH3D does not currently support MODFLOW2000 )
• Accurate and efficient tracking procedure
  Automatic tracking stepsize control procedure that achieves user-specified error criteria with minimum computational effort.
• Improved handling of weak sinks and distorted grids
  Algorithms for the effective handling of weak sinks/sources and distorted model grids.
• Postprocessing programs
  Includes a complete set of post-processing programs for plotting pathlines, front positions and capture zones using Golden Software's Surfer.
• Dynamic memory allocation
  PC version is compiled with dynamic memory allocation to efficiently reserve only the necessary computer memory.
• Distributed with source code
  Comes with source codes written in standard Fortran 90.
