WaSiM (Topmodel)

Important: version 10.02.03 and higher provide netCDF support. That requires a few additional libraries (DLLs) to be installed on your system. Please download and install either the lib-package for 32-bit or the lib-package for 64-bit before using WaSiM on Windows and/or download and install the latest netCDF package from the internet. On Linux, you need to install a netCDF package as well (see development details for more information)


Actual release version (may still be unstable -> it is recommended to always use the latest patch, if one is provided!)

Version 10.07.02(2023-11-12) More »
Mainly a compatibility Build with Richards-Model
  • open netCDF files extended to 2000
  • Grid-filename numbering for annual averages and sums: year will be written with four digits now (instead of only two)
  • writecode = 8 works now immediately after reading the standard grids and variable grids and is applied only one single time to the filled but otherwise unchanged grids (e.g. the land use or soil codes are still orginal, aquifer depth is not changed according to the soil depth etc.). Thus, the written grids with the extension.filled could be used to replace standard grids that have not all cells filled
  • correction for column number for reading from external abstraction files
    • and several bug fixes (see details of model development)

Patched versions (stable version only are listed here)

Version 10.05.05 (2020-11-15) More »
  • new (only Richards-version): implementing changes into the main branch of WaSiM that were made by Matvey Debolskiy during his PhD thesis to better model the frozen depth in a permafrost soil (only matters when heat transfer is used)
  • bug fix: interpolation method 9 did not handle memory for the filename read from the gridlist correctly (was allocated too late)
  • and several bug fixes (see details of model development)
