MODFLOW-2005 updated - again

GWF2BAS7 -- Fixed bug that caused MODFLOW to incorrectly continue
execution when solver closure criteria are not met and the
percent budget error is negative. The bug occurred even when the
new STOPERROR option was not being used.
There was also an updated version of ModelMuse released today.

Richard,
Just wondering if you could suggest for modelling softwares options available to simulate the unsaturated & saturated flow and transport model (salinity, hydrocarbon and density dependent), with the requirement below?
The software modelling requirement requests for ‘coupled unsaturated and saturated flow and transport’ while there is an option that the saturated zone should be simulated in 3D while the unsaturated zone could be modeling in 1D or 2D. If the software to be used has the capability of coupling the unsaturated and the saturated flow system in 3D it will be welcome. Otherwise, the flow and transport in the unsaturated zone may be simulated in 1D or 2D using appropriate software and the results taken in to account during the setting of the saturated zone 3D model.
How about a software that can be used to build a conceptual model for this purpose?
Kuwait only freshwater aquifers (Raudhatain & Umm Al-Aish) were contaminated as a result of damage and detention of oil wells during the 1990 Iraq invasion of Kuwait. The aquifers were contaminated by entertainment and discussion of petroleum contaminants that subsequently leached with rainwater. Further collateral contamination was caused by the infiltration of salt water; which was introduced as align result of its use in extinguishing the oil well fires after liberation.

flow in the vertical direction and is coupled with the saturated system
beneath it. MODFLOW does not simulate solute transport but its results
can be used with MT3DMS to simulate transport of solutes. MT3DMS only
simulates transport in the saturated zone. Neither MODFLOW now MT3DMS
simulate non-aqueous phase liquids (NAPL).
Good luck with your proposal.

Not user-friendly, but suited just for your needs. I haven't run Sutra since
the Fortran era, but there might be some options available.
And it's finite element, thank you very much ...

The Unsaturated Zone Flow package in MODFLOW can simulate unsaturated flow
in the vertical direction and is coupled with the saturated system beneath
it. MODFLOW does not simulate solute transport but its results can be used
with MT3DMS to simulate transport of solutes. MT3DMS only simulates
transport in the saturated zone. Neither MODFLOW now MT3DMS simulate
non-aqueous phase liquids (NAPL).
Good luck with your proposal.

Thanks Jim,
How is NAPL handled in modflow-surfact then? How can we predict and propose remediation options & timing if NAPL is not simulated.
What about the vadose zone simulation for the solute & hydrocarbons?
Where is the coupling using modflow-surfact?
Idealy, we need to simulate the vadose, capillary & water table. How can we integrate modflow-surfact with the1D or2D contaminant transport analytical tools? Any case study or previous works relared to this?
Regards
Yohannes

I sent e-mail via linkedin which I would like your opinion in the topic below:
Using MODFLOW-SURFACT coupled with GV(using ponding for the recharge- excess recharge will be removed from the system)- I will run scenario for 100 years including during extreme rainfall, and I presume I can be able to delineate the extent of flooding but how about the mass balance (does it consider the flooded volume of water as an outflow?) Do I need to include drain package for the prediction? Can flooding be simulated using MODFLOW 2000 and MODFLOW NWT/2005 as well?
Thanks

Dear friends and respected seniors, I have a simple question regarding input in visual MODFLOW 2005 model. If we are not having pumping data and we are using pumping in terms of negative recharge so it is correct process or not.we are giving input on the node basis.Actually I have doing the unconfined modelling taking 5 layers with 10 meter interval. In recharge tab (window) of groundwater model, we are using first layer as a recharge and last layer as negative recharge (because the pumping well is not present) so it is correct process or not. please help me out.
