File-Contents (in Catchwords)

  1. model type for calculation or provison of hydrodynamics as well as salt and or temperature transport the following methods are possible:
    1. No_Hydrodynamic_Model
    ;
    2. Read_Hydrodynamic_Data_From_File
    ;
    3. Untrim_Hydrodynamic_Model
    : the three-dimensional numerical model UNTRIM will be applied.
  2. existing files for hydrodynamics, salinity, temperature and suspended load when method Read_Hydrodynamic_Data_From_File was selected.
  3. times, if the global default values which have been specified in a file of type untrim_main.dat shall be replaced by the values specified for this physical submodel; the following specifications are possible:
    • control of simulation (period and time step);
    • area-/volume oriented output of results;
    • profile oriented output of results;

  4. name and type of different input files; the following specifications are possible:

    • (optional) file with profile topography (filetype profil05.bin);
    • (optional) file with a list of specific locations (filetype location.dat);
    • (optional) initial condition for hydrodynamics, salinity, temperature and suspended load (filetype dirz.bin.r, dirz.bin.i and dirz.bin); in addition to the name of the file also date and time for the initial condition must be prescribed.
    Notice: for a three-dimensional simulation the results of a previous two-dimensional simulation can be used too.
    • (optional) alternative initial condition for salinity (filetype dirz.bin.r, dirz.bin.i and dirz.bin); in addition to the name of the file also date and time for the initial condition must be prescribed.
    Notice: for a three-dimensional simulation the results of a previous two-dimensional simulation can be used too.
    • (optional) alternative initial condition for temperature (filetype dirz.bin.r, dirz.bin.i and dirz.bin); in addition to the name of the file also date and time for the initial condition must be prescribed.
    Notice: for a three-dimensional simulation the results of a previous two-dimensional simulation can be used too.
    • (optional) alternative initial condition for suspended load (filetype dirz.bin.r, dirz.bin.i and dirz.bin); in addition to the name of the file also date and time for the initial condition must be prescribed.
    Notice: for a three-dimensional simulation the results of a previous two-dimensional simulation can be used too.
    • (optional) description of soil identification numbers (filetype soil.dat);
  5. name and type of different boundary data files;
    Notice: aforementioned files may be generated using program UTRRND.
  6. name and type of different output files; the following specifications are possible:
    • area oriented output of computed results (two-dimensional) in the overall model domain or in a tile (each of the subsequent files can be optionally specified):
    • volume oriented output of computed results (three-dimensional) in the overall model domain or in a tile (each of the subsequent files can be optionally specified):
    • (optional) output along profiles of computed results (depth-averaged data) along selected predefined profiles:
    • water level elevation,
    • depth averaged current velocity,
    • depth averaged salinity,
    • depth averaged temperature,
    • depth averaged suspended load,
    • depth averaged density,
    • depth averaged hydrodynamic pressure and
    • depth averaged vertical viscosity.
    • bottom shear stress
    (filetype dirz.bin.r, dirz.bin.i and dirz.bin);

    • (optional) output along profiles of computed results (three-dimensional data) along selected predefined profiles:
    • current velocity,
    • salinity,
    • temperature,
    • suspended load,
    • density,
    • hydrodynamic pressure and
    • vertical viscosity.

    Notice: Files contain synoptic data sets. Time series informations for specific locations can be obtained applying the program ZEITR on these data; These files will be initialized with standard values immediately after opening.
    • (optional) output of results for specific locations, i.e. for three-dimensional data:
    • current velocity,
    • salinity,
    • temperature,
    • suspended load,
    • density,
    • hydrodynamic pressure and
    • vertical viscosity.
    (filetype dirz.bin.r, dirz.bin.i and dirz.bin).
    Notice: Files contain synoptic data sets. Time series informations for specific locations can be obtained applying the program ZEITR on these data; These files will be initialized with standard values immediately after opening.
    • (optional) restart-data for hydrodynamics, salinity, temperature and suspended load (filetype dirz.bin.r, dirz.bin.i and dirz.bin). Notice: these files contain consistent synoptic data sets for the staggered computational grid and can therefore be used as initial conditions for a subsequent simulation; because they are defined on a staggered grid they cannot be used in conventional postprocessing programs.
