Hi to the members of this group. That's my first post ever here ! I'm performing a preliminary research concerning the possibility to modelize a chalk aquifer...
I would set up the model with at least two layers, as unconfined aquifer. Then, in the top layer, assign two conductivity areas: one with high, for the...
hi.. I'm a student and i'm using visualmodflow for my thesis.. can anyone tell me how plan as boundary a CONSTANT HORIZONTAL FLUX (m3/sec)?Can i use GENERAL...
Hi there, Regarding ur boudary condition, you have a constant horizontal flux. But u can't find such type of boundary in visual modflow. The thing u need to...
Hi Paulo, During 'creation of a new model' in 'model domain' window, u might put such a value of "Zmax" (i.e bottom) in layer 1, which is above the initial...
It seems I am lacking some basic understanding of hydraulics: Why does 1 mm/a of recharge to an aquitard result in a water level rise of 1.000 m? Dieter...

Because you are probably talking about a steady-state simulation, isn´t it? I had a problem like this too. If the K is too low, the porous material is not...
Yes, it is a steady-state simulation. Am I right in assuming that steady-state simulation means that water levels are calculated for a quasi infinite time...

Hello, I'm trying to run a Visual Modflow model in RT3Dv2.5 using Instanteneous aerobic decay of BTEXN. I've put in a constant concentration for BTEXN and...
Hi Arjen, have you checked the *.ot file in order to know if RT3D makes the computation ? Daniele ... Da: visual-modflow@......

Well, I suggest you to check the water velocity to see if the time scale that you are using in the transport simulation is compatible with it. It could be just...
Dear Sir How can I find SUB package of MODFLOW in Visualmodflow3.1 How can I calculate earth subsience of drawdown by VisualModflow3.1 sincerly yours...
Good Day, I invite suggestions from the learned members regarding most appropriate methods to estimate groundwater recharge from artificial recharge and...
Dear Dr.Kumar, I have visited your web site. I am interesting your works. Could you please suggest me about simulate contaminants in field condition ?...
Dear Dr. Srilert Contaminant transport in hydrogeologic systems requires knowledge of transmissivity, storage coefficient, and dispersivity. Techniques for ...
Hello. I´m new to this group and also pretty new to vmf. I have a problem that I´m looking at and I feel I could use some guidance. I´m planning to do a...
Hello. I am designing a model in modflow (using pmwin) for a 1 layer confined aquifer with known thickness and transmissivity, recharge and evt. I have some...
Hello everybody, I would like to ask which is the better computer configuration to run visual modflow as fast as possible. I'm actually working with a very ...
Hi, 1.- That difference always occurs, but is very little (in my cases is in the second decimal, with head ranging between 0 to 900 m.), so it must be a...
Dear group members, I am just starting to use MODFLOW and I am hoping to find some support here, since I seem to run from one problem into the next, with what ...
dear group, started learning groundwater modeling. To begin modeling, I need initial condition. I know the following: - observation well data - one river...

Hi, You don't need initial condition if you do a steady state simulation; in this case you can apply an initial condition in order to minimize elaboration...
