  1. Hi All, I would like to check the effectiveness of using canals to draining water into the ground with the gravity (opposite of drain) without using injection well. How do I model this in GMS modflow? Please let me know your suggestions. Thank you, Lalith
  2. Hey, I have a problem, when I use the drain package. I want to model streams with the drain package in the form of polylines. Additionally, I want to apply a general form of draining using the drain package in the form of polygons. However, when I map both coverages to MODFLOW NWT, the model writes: Array allocation failed: ilupc-iluk. What does this mean? I have tried mapping each coverages separately and when MODFLOW NWT as no problem running :S Best regards Merete
  3. Hi I have build a steady state model in GMS using the conceptuel approach generating solids and streams. I wanted to incoprate drains into my model using a polygon based shapefile. This is no problem until I run a simulation check in MODFLOW. Then I get the folowing error: Error: Drain elevation is below cell bottom in cell i=31, j=52, k=1 for stress period 1. .... ... ... and so on for several cells. What does this error message mean? The model run without any problems. Thanks-
  4. 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 t
