WaSiM 10.07.02 (Richards)

ice wedge degradation implemented


  • new functionality for ice wedge degradation: ExcessIceFactor is initialised as additional water equivalent and hgeo and theta are initialized according to the excess ice content. When running unsatzonmodel, actual theta_res and theta_sat are set for each layer in an ice wedge. All functions of the richards-solution (in unsatzon and soiltable) were extended by handling different thetasat and thetares values for ice wedges (e.g. if the normal theta_sat is 0.4 and thetares is 0.1 but with excess ice it is 0.65 and 0.05 resp., a return theta of 0.25 from the h_calc function (which is exactly 50% of useable water in the soil with the original theta values) is changed into 0.35 (which is also 50% of usable water in the soil with the excess ice - here, including the ice of course). After each model run, the changed DHM is written back to the input grid directory of the original dhm with the name extension _out. This could be used for coupling several runs (rename it first and remove the _out-extension!) IceWedge degradation can be used by
  • adding a new control file section like this:

    [ArcVegIntegration]
    1 # do_ArcVeg; 0=no, 1=yes
    $outpath//$ExcessIceStack # stack, factor that expresses the excess ice in that soil layer
    $Writestack # Writecode for this stack

  • adding two standard grids, containing the ice wedges upper and lower depth for each cell (-9999 if no ice wedge is present)

    $set $IceWedgeUpperDepth = $grid//.iwdgup
    $set $IceWedgeLowerDepth = $grid//.iwdglo
    .
    [standard_grids]
    xx # number of standard grids
    ...
    $inpath_grid//$IceWedgeUpperDepth IceWedgeUpperDepth fillcode = 0
    $inpath_grid//$IceWedgeLowerDepth IceWedgeLowerDepth fillcode = 0

  • fixed routing with -mode:routing for lakes with abstraction rule "HydraulicConnection". No routing took place at all because there usually was no connection (both water levels were 0 but channel bottom level was above). To make this work, the routing description must contain two other values: A0 and W0 (A0 = initial area of the lake in m2, W0 is initial water table height in m a.s.l.). Example:

    ...and SP 1 ( file = $outpath//spv_01_sub09.//$code//$year , V0 = 4.69261e+10, A0 = 473.25E6, W0 = 395.107, C0 = 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0, dTmin = $dtmin1 )

    0 and W0 must follow V0 in this order. A0 and W0 must be provided for all lakes that are connected hydraulically.
    V0, A0 and W0 can/must be taken from the last entry in the lake-statistics file of the previous run manually, since -mode:routing doesn't read these Values from the richards-storage file.
  • 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)
