SEAWAT
• Density, viscosity dependent
groundwater flow and transport
• MODFLOW – MT3DMS coupling

6. MT3DMS
• 3D reactive transport
• Simple reactions

7. RT3D
• Much like MT3DMS, but …
• More complex reactions (e.g. reactive
chains, inter-species reactions
• Predefined reaction modules
• User-defined reaction module

Control via run-file
• All input (referenced) in one file
• One block per package
• Use of keywords
e.g. NPER = 12
• Use of defaults
bv. WRITEHELP = FALSE
• Use of ”macro’s” and “tokens” for compacted
input
