Hello Jeane, it depends on the size and flow of the springs and the connectivity with the aquifer. The main difference between river and drain packages is that...
Hallo Jeane, The drain boundary package in MODFLOW is designed to simulate the effects of features e.g. agricultural drain, which remove water from thw aquifer...
Dear Shailendra, if you want to use MODFLOW software to simulation groundwater flow or contamination, u need the below parameters in the first step. Parameter ...
Dear all, I am just new member. Now, I am doing research about mining that plan to use visual modflow to simulate in my study site. Could anyone ever train...
Maybe, it's a good start point. http://www.swstechnology.com/training_course.php?ID=8 ... Da: visual-modflow@......

I think the difference between one and the other is that a drain takes the water out of the system and there is no interaction with the groundwater, while a...
Cristina, so far I used river, once more people suggested river, and I obtained a good calibration. But we are cheking the fields data and the model is not...
Hi, I am a civil engineer from Chile, I work in groundwater exploration. I have two doubts about Visual MODFLOW: 1.- I found a difference between the water...

Hallo, 1) You consider the computed heads obtained from Calibration Graph( Calculated vs. observed head) in steady state model. 2) After running the model in...
Dear Ampro, I guess the data you have put is been interpolated as you need to convert point data into continuous surface. I have done some work for possible...
Hello everyone, I have 6 wells in study area that i want evaluation amount of phosphorus as contamination and then simulate the situation of groundwater...
Hallo, General head boundary is better because Constant head boundary conditions can have a significance influence on the results of a simulation and may lead...
Hello everyone, I have met a problem. I set up a uniformed domain with constant heads at east and west boundary. East boundary is influent side and west,...

Hello, I'm having problems when I try to use initial heads from a previous run. I get a messenge like this "your initial heads are below the bottom of layer 1...
Hello Members, I would like to know does anybody has some experience in using HSSM, case studies or reliability of software. Also, some alternatives are...
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...
