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.
- 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.
