Hi all, I would like to simulate a ISCO experiment, that is the injection of KMnO4 in groundwater which will react with some sorbed hydrocarbons. The oxidant...

Hello everyone, Thanks for the response to my previous question. I am using visual modflow for contaminant transport. while running the model i get error...
Greetings, Can anyone tell me if Modflow can effectively model fractured aquifers? If yes, how small should the grid cells be? We normally measure the...

I am relatively new at groundwater modelling. I am currently trying to model groundwater flow for a particular catchment using gms (modflow) How do i go about...
Hi Guillaume, MT3DMS and both standard versions of RT3D (v.1 and 2.5) have no specific reaction modules to simulate effects of permanganate injection. We also...
You can approximate a granular media aquifer with a fractured media aquifer, as long as there are quite a few fractures and the cell size is "large" relative...

Dear all, I have built a hydrogeological model (steady and transient flow) by Modflow using a convergence criterion of 0.01. Now I m performing previsions but ...

Dear Eakambaram Suburayalu, I assume that you are modelling only the unconfined aquifer system i.e. top aquifer. There is no problem in selecting partially...
Dear FAKIR Younes, You may try with different solver for convergence of your model. You may slightly increase your convergence criteria if there is large...
Partial penetration for monitoring groundwater elevations in your unconfined alluvial aquifer should be OK. It might be a problem if you have significant...
Fakir, What is your mass balance in the model? If it is reasonable than try to increase your convergence to say 0.05 or 0.1 re-run the model and check the mass...
