  6. Dear all, I do appreciate if you can help me with this problem: I had a square area with 4 cutoff walls around it. and some wells are going to be inside the area to dry it. first I modeled a cross section in Seep2D to see how the wells dry the area. I attached a picture of results. the results looks fine. but I wonder why when I model it in Modflow, as 3D model, the seepage (vertical gradient) is not as continuous as it was in SEEP2D . I attached image here. it sounds like any cell in one aquifer layer has almost the same head pressure along its depth!!! so should I divide my aquifer to multiple layers to get more accurate results? Thank you for any help.

  9. Dear All, I have been using PEST for calibrating my project using GMS. I have defined a set of pilot points for HK and want to assign a different min. & max. for each point in the calibration process. Does GMS support such idea? Any insights/helps would be appreciated. I look forward to hearing from you soon.

  11. Hi Im trying to modell the drawdown and the drawup of brine by simulating seepage into a tunnel. The modell is in 2D, width and "height/depth". I'm wondering what the best way to do this is. DRAIN seems to be a good way to take the seepage/leakage into the tunnel away from the model because as I have understood it, it couples the head and the seepage to each other. The question is, how do I calculate the conductance-parameter, or should I just try different values to get an appropriate value of the seepage? How is the DRAIN affected by the elevation and head above? Is the elevation-parameter the level at which the drain/tunnel is situated or the head above? Is there any way to easily create a gradient of brine in SEAWAT? The brine is has more salt at deeper depth in the area being modelled. Is this the best way to modell the situation, or do you have any other way to suggest? WIth regards /robinb
  12. Dear Sir/Madam, I am using GSM/modflow+mt3d to do a relative simple simulation of contaminant transport. I just got some problems and I hope you can help me out. I have domain which was divided into two layers. I have a varied water head boundary condition on upper and lower stream of ground water, a rainfall recharge on the top and all others are no flux boundaries. Besides these boundary conditions, I have three point sources which contains three species each. Here is my problem. 1) First, I built the model via conceptional approach and specified the point sources (flow rate and concentration) by add points in the "sources and sinks" coverage and change their type to "well", and then input the flow rate and concentration in the property of the the point wells. Did I do correctly? 2) In the flow simulation with modflow, I did specify the horizontal hydraulic conductivity and anis Kv in the "layer 1" and "layer 2"coverages. Howerver the "check model" brefore I run modflow gived me warning messages: the horizontal hydraulic conductivity value is zero in layer 1 (and layer 2); the anisotropy value is zero in layer 1 & 2; the specific yeild value is zero in layer 1 & 2, and the specific storage value is zero in layer 1 & 2. 3) In the transport simulation with mt3d (advect + disperson+ point source sink package), I got similar warning message in Disperson Package that Dispersivity value is zero in cell...; and in the Point Source Mixing package that concentration of zero found in well poing source sink for stress peiold... I really appreciate your help. Thanks for your time. Best wishes, Darcy
