Output variables in sedimentΒΆ

  • There are 4 different ways to write variables in sediment.
../_images/sedim_outputsed1.jpg
  • User chooses the option with parameters listed in namelist namsedoutput (paraMUSTANG.txt)
    • choice_nivsed_out : 1,2 3 or 4
    • nk_nivsed_out : number of saved sediment layers
    • ep_nivsed_out (mm) : 5 values of sediment layer thickness (mm), beginning with surface layer (choice 4). Last layer (6th) is an integrative layer.
    • epmax_nivsed_out (mm) : maximum thickness (mm) for output each layers of sediment (choice 3). Below this thickness, output an integrative layer.
  • The following variables are written to the output file :

Output sand variables in water column (*if key_sand2D*)

  • If key_sand2D is activated, sand variables with l_sand2D =. TRUE. (in variable.dat) can be written in two different ways
    • either l_outsandrouse=.FALSE. (in variable.dat) : only the average value in the water column, determined in 2D by the model, is written at k = 1
    • either l_outsandrouse=.TRUE. : a profile over the entire water column is artificially reconstructed from the calculated average value according to a Rouse profile.
