Developments - iMOD

version iMOD5.0

• iMOD GUI
  • MetaSWAP Analyser
    This tool is not processing the MetaSWAP files from an iMODFLOW5.0 model correctly and as a result will display incorrect values/figures.
    Reason is a change in the format of the MetaSWAP input file: luse_svat.inp.  The column positions 1-144 are unchanged, the other columns are changed (see also the Dutch Release Notes MetaSWAP_iMOD5).
    MetaSWAP files from an older iMODFLOW version are still processed correctly by the MetaSWAP Analyser.
    > Workaround: rewrite the columns in the luse_svat.inp file of an iMODFLOW5.0 run according to the format of MetaSWAP V7.3.3.2.
• iMOD TUTORIALS
  • Error in the steps after running a model. 2 Examples. 1) Tutorial 4 when trying to create pathlines and 2) running iMODFLOW for Tutorial 8 (Surface Flow Routing). Reason: iMOD is missing budget files like BDGFLF or BDGSFR for additional steps because by default from iMOD5.0 ONLY HEADS are saved.
    > Workaround: before starting a modelrun from the Window 'Simulation Manager', go to the OUTPUT tab first and select the additional topics to be saved. E.g. '(BND) Boundary Condition' for all layers of '(SFR) Stream Flow Routing' for layer 1.  
• iMOD-WQ

  • Input of well concentrations (CWEL) in the SSM package
    The code derives from the given file extensions in the [SSM] package of the iMOD-WQ runfile whether for the input of the WEL concentrations (CWEL) IDF files or IDF files are used.
    Currently the code does this by checking the filename for P=1, T=1 and L=1 (e.g. CWEL_P1_T1_L1). However, this fails if there is no such file, i.e. if there are no wells for P=1, T=1 and L=1.    
    > Workaround: use a dummy file for the input for CWEL_P1_T1_L1. In case of IPF input this file can be empty. In case of IDF input, this can be an IDF with only nodata values, or zeros (actually, the chosen values do not matter because since there are no wells for P1_T1_L1, the corresponding concentrations are not used).
