Advanced three-dimensional
groundwater modeling with MODFLOW
Dedication to MODFLOW support
- All versions of MODFLOW supported: NWT, 2005, 2000, 96, 88
- Many MODFLOW packages supported (see table on right) with more to come
- Guaranteed to read any model that MODFLOW can run
- Support for MODFLOW related packages such as MODPATH, MT3DMS, RT3D, PEST, and built in ZONEBDGT
- Full suite of manual and automated calibration tools including PEST, Parallel PEST, Monte Carlo simulations, calibration targets, plots and charts
- Large model support (grid cells, stress periods) with smart memory management and caching for maintained responsiveness
- Transient data support in real date/time format
- Interpolation of transient data
- Stochastic Simulation tools including Monte Carlo, Latin Hypercube, Gaussian Field, T-PROGS (better than indicator kriging) and Risk Analysis wizard for capture zone and transport analysis.
