Hi, I'm modeling a contaminant transport with MT3D while activating MNW2 package for multi-layered model. It seems MNW2 package gives appropriate value for head and drawdown. But when I check the concentration after running MT3D, it gives erratic value on multi-nodes well location. I put negative pumping rate on mnw to simulate pumping well and the concentration is exceeding the upper limit of modeling domain. I wonder anybody experienced same (or similar) problems? If so, any suggestion would be appreciated. Thanks, Ki
Hello everybody I noted GMS has values for porosity in both MODFLOW and MT3D. In MODFLOW menu (MODFLOW options) one can enter values for porosity, although porosity is not used in flow computations as far as I know. Also in MT3D menu it is essential to enter porosity value. In the model I have (which is a SEAWAT model) I entered values for porosity in the MT3D options, but I noticed there are different values -by default- in the MODFLOW options. Which values does the model consider in this case? and why is there an option for porosity in MODFLOW? Thanks
