WaSiM (Richards)

Actual release version (still unstable -> uses latest patches!)

Version 10.00.00(2017-07-04) More »
Layered Snow model and optimized surface routing model
  • Layered snow model allows in combination with the heat transfer model and any snow melt approach a better modeling of soil temperatures by accounting for the snow pack. Heat transfer and water transport are computed for each snow layer as for any soil layer, so teh snow is in fact handled as a series of dynamically growing and decreasing soil layers
  • Surface routing can now use a new algorithm that uses a set of linear equations for each connected group of cells rather than doing the routing locally only. That speeds up the model and makes backwater locations surface (lakes, ponds) much smoother. However, there may occur some artifacts due to the fact that the used 2D-algorithm has some limitations, especially when the ground level changes rapidly and the water depth is shallow
  • a lot of bugfixes, see model development details for more details

Patched versions (stable version)

Version 10.00.02 (2017-09-14) More »
    bug fixes: several small memory leaks and some wrong calloc/delete combinations fixed. These errors were mainly existing in the initialization and cleanup parts, not in the main tie step loop, so it is not too probable that less run time errors will occur (they may also be connected to the MPI libraries)
