  1. Hi Allan, The step-by-step solution you provided works totally fine. Thank you very much for you help. Cheers
  2. Hi All, I am tyring to calibrate a steady-sate MODFLOW model using PEST in GMS 8.0. Does anyone know where can the initial Marquardt lambda (RLAMBDA1) value be specified? I have performed an initial (unsuccessful) run and it seems that the default value is set 0.01. However, I would like to increase this value somewhere in between 1 to 10. Yet, I can't seem to find any input dialog for this option. Any help is much appreciated! Cheers Bernard

    Zone Budget

    Hi all, Does anyone know of a way in GMS 8.0 to export/print out a text file containing the flow budget specific to "zone budget" zones only? Cheers Bernard
  4. Thanks for your reply Sean. As it turns out, by using a polygon in the map module to assign ET, one can only specifiy either a constant (or time series) value for the ET elevation parameter. Here is a step-by-step solution that was provided to me which worked perfectly fine: Set up your ET conceptual model and assign your max ET rate and extinction depth using the polygons. Map the values to the MODFLOW grid. (it sounds like you already know how to do this). Ignore the ET elevation for now. Create a “matching 2D grid” by selecting the Grid|Grid->2D Grid command in the 3D Grid Module. Go to
  5. Hi, I am trying to use the Evapotranspiration (EVT1) package available in GMS 8.0 to simulate groundwater evapotranspiration in certain areas of a model domain where the water-table is close to the ground surface. To this end, I have created a coverage (using the conceptual model approach) and selected the three following areal properties: Max ET rate, ET elev. and ET extinction depth. From the GMS dialog available for this package, I seem to understand that only a constant value can be set for the ET elev. parameter. However, I am wondering if there is a way to define a range of ET elev. valu
