Introduction to GW model GUI

- What is the PMWIN ? PMWIN

a pre-/post-processing of GW simulation systems supported various GW models (i.e., MODFLOW, MT3D, MT3DMS, PMPATH, PEST2000, UCODE, …)

Pre-processingPrepare/Converse/Create MODFLOW input data

visual. –> numerical method Post-processingAnalyze/Coverse/Present output to Graphics and

other attached models, like PMPATH and MT3D etc.numerical method –> Visual.
