  1. Will GMS split wells across multiple layers if the screen spans and associate the appropriate percentage to each? If so, how does it split it? by screen length per layer? per wet screen length per layer? Does it also consider hydraulic conductivity and transmissivity in the calculation?
  2. Please consider adding support for drawdown observation data - particularly as it would pertain to parameter estimation simulations. For MODFLOW-2000/2005/NWT where the observation process is being used, this change would be relatively easy to implement via a change to the ITT flag value. For MODFLOW-USG, the change may be even easier to implement through an additional call to usgmod2obs that extracts relevant simulated drawdown values. It would also be useful to provide an option to pause PEST execution following creation of the input files - the control file, in particular. -Mike
  3. Hello to All, I have a question regarding the inline steering option that allows the coupling of CMS Flow and CMS Wave in order to simulate the effects that waves may have on currents and vice versa. My question arises after running multiple simulations in which we are not seeing any effects in current magnitude from any given simulated wave spectra for multiple wave events over a given time series. We are trying to replicate a given time series of currents, water level, and wave events from an in-situ ADCP that is within the model domain, aka our calibration point. I have included a plot of the results illustrating my problem which shows the simulated wave height and current magnitude (metric units) at our calibration point which is in 7 meters of water and located approximately mid domain about 380 meters offshore . With a given wave event reaching a peak height of 2+ meters we see little change in current magnitude during the event where as at the in situ gage we see a significant increase in velocity. Now I realize this is a depth averaged model and I compared it to the depth averaged result from our ADCP to keep things on the same page. However the truly confusing part is that in the nearshore zone (less than 200 meters offshore) we see a significant increase in current magnitudes during a wave event similar to what you would expect in reality (red is the nearshore observation point, wave height and Magnitude). So it appaears that we have a spatial problem relative to our calibration point. I have tried expanding the grid further offshore by several hundred meters on a constant 20x20 meter grid with no change in results. At this point I am stumped after adjusting the various coefficients available within SMS. I attached a screen shot of the last values used in the Flow Parameters section in case anybody has any suggestions. I have tried adjusting the variables from 0 to 1 with multiple steps in between with marginal changes in results. We are currently running SMS 11.1.11 64bit and I would be greatful if anybody has any suggestions or ideas as to what I might be doing wrong in order to see an increase in current magnitude at the calibration point. Thank you in advance for your time. Cheers, Joe
