MODFLOW Development Plans

Tentative MODFLOW 6 Development Plans

MODFLOW 6.6.0

• NetCDF input and output

MODFLOW 6.7.0

• uTVD: Improve TVD for unstructured and structured grids
• Add MVE/MVT support for parallel runs

MODFLOW 6.8.0

• Channel Flow Model
• Overland Flow Model
• Richard's Flow formulation for Node-Property Flow (NPF) Package
• Process-Based Stream Temperature Model

Miscellaneous Ongoing Efforts

• Creating packages from memory
• Conductance recalculation as needed for API
• Condense advanced package functionality into parent class

Requested New Model Types

• Watershed Model
• Linear Network Flow Model

Requested Features

• XT3D by connection
• Save state mechanism
• Transport and CSUB compatibility #1101
• Allow GWT IDOMAIN to be different from GWF IDOMAIN #1129
• Add lag time to Water Mover #1170. Consider adding rudimentary options to MVT/MVE that would alter concentrations/temperatures of water passing through the MVR #1314, #2552
• Add observation utility for GWT SSM Package #1014, #1120
• Allow solver settings to change by stress period #589, #1001
• Allow Initial Conditions (IC) Package to optionally read heads for subsequent periods #826
• Steady state option for solute transport #799
• Alternative input format for MAW, SFR, LAK, UZF #548
• Support multiple OPEN/CLOSE statements within a PERIODDATA input block #2026
• Support for models with GWT-GWT exchanges for (parallel) runs where GWF flow are read from file #2490
