I've written reviews of Visual Modflow and Processing Modflow for Windows (PMWIN) Argus ONE and Groundwater Vistas. I also contributed to a review of GMS 2.0 (Ground Water, Vol 35, No. 4 p. 728-729.). The developers of GMS have posted that review on their web site. On this page, I briefly list my opinions about the primary differences I see between the three programs. Newer versions of the Argus ONE MODFLOW interface, Visual MODFLOW, Processing MODFLOW have been released since these reviews were written. Thus those reviews are now outdated.
One person has sent in a comment about Visual MODFLOW.
two comments have been sent in about Argus ONE:
|Argus ONE 4.2 with MODFLOW/MT3D PIE 1.0||Visual Modflow 2.0||PMWIN 4.0||Groundwater Vistas 2.15|
|Operating system||Windows 95 or Windows NT||DOS (but can run under Windows too).||Windows (but can't perform many common Windows functions).||Windows 95, 98, and NT|
|Supplementary Packages supported||PCG2, DE4, BCF5||BCF2, PCG2, HFB, CHD||BCF2, PCG2, HFB, CHD, STR, IBS, RES, DE4||BCF3, PCG2, HFB, CHD, STR, IBS, Variable anisotropy package|
|Unsupported packages included in the MODFLOW executable||All USGS Packages plus variable anisotropy package||STR, GFD, BCF3||BCF3, GFD1, TLK1||TLK, DE4, GFD, RES|
|Supported programs||MODFLOW96, MT3D||MODFLOW88, MODPATH, ZONEBDGT MT3D||MODFLOW88, PMPATH, Water Budget Calculator, MT3D, PEST (UCODE in PMWIN 5)||MODFLOW88, MODFLOWT, MODFLOW/SURFACT, MODPATH, MT3D, RT3D, PATH3D, PEST|
|Version of MT3D supported||public domain||public domain||public domain||public domain|
|Model types||3D, quasi-3D||3D||3D, quasi-3D||3D, quasi-3D|
|particle tracking||not supported||steady state, transient||steady state, transient||steady state, transient|
|ease of use||very easy||very easy||very easy||very easy|
|automatic specification of proper stress periods||no||yes||no||no|
|Handling of cell properties during grid refinement||best||better||good||better|
|ability to expand physical model dimensions||yes||no||yes||yes|
|ability to inport data from MODFLOW input files||no||yes||no||yes|
|editing modes||plan view||plan and cross-sectional view||plan view||plan view|
|ability to directly edit all input parameters||no||no||yes||yes (except recharge layer)|
|special features||Extremely flexible methods for entering property values, Source code for MODFLOW PIE is in the public domain and can thus be modified by anyone with the requisite skills to support additional packages or methods, New interpolation methods and other new functionality can be supplied by the user by writing plug-in extensions.||WHS solver, and data interpolation||data interpolation, stochastic field generator||MODFLOW documentation converted to help files, Telescopic mesh refinement, simulate variable density conditions using equivalent fresh water heads. calibration statistics and plots|
|Ease of use of water budget program||not currently supported||easier||easy||easier|
|theoretical maximum model size (may require enormous memory to achieve)||limited only by MODFLOW96 itself (200 layers maximum) and computer memory||500x500x60||2000x2000x80||limited only by MODFLOW 88 itself 80 layers maximum) and computer memory|
