Bases: flopy.mf6.mfpackage.MFPackage

ModflowGwtlkt defines a lkt package within a gwt6 model.

Parameters:
  • model (MFModel) – Model that this package is a part of. Package is automatically added to model when it is initialized.
  • loading_package (bool) – Do not set this parameter. It is intended for debugging and internal processing purposes only.
  • flow_package_name (string) –
    • flow_package_name (string) keyword to specify the name of the corresponding flow package. If not specified, then the corresponding flow package must have the same name as this advanced transport package (the name associated with this package in the GWT name file).
  • auxiliary ([string]) –
    • auxiliary (string) defines an array of one or more auxiliary variable names. There is no limit on the number of auxiliary variables that can be provided on this line; however, lists of information provided in subsequent blocks must have a column of data for each auxiliary variable name defined here. The number of auxiliary variables detected on this line determines the value for naux. Comments cannot be provided anywhere on this line as they will be interpreted as auxiliary variable names. Auxiliary variables may not be used by the package, but they will be available for use by other parts of the program. The program will terminate with an error if auxiliary variables are specified on more than one line in the options block.
  • flow_package_auxiliary_name (string) –
    • flow_package_auxiliary_name (string) keyword to specify the name of an auxiliary variable in the corresponding flow package. If specified, then the simulated concentrations from this advanced transport package will be copied into the auxiliary variable specified with this name. Note that the flow package must have an auxiliary variable with this name or the program will terminate with an error. If the flows for this advanced transport package are read from a file, then this option will have no affect.
  • boundnames (boolean) –
    • boundnames (boolean) keyword to indicate that boundary names may be provided with the list of lake cells.
  • print_input (boolean) –
    • print_input (boolean) keyword to indicate that the list of lake information will be written to the listing file immediately after it is read.
  • print_concentration (boolean) –
    • print_concentration (boolean) keyword to indicate that the list of lake concentration will be printed to the listing file for every stress period in which “HEAD PRINT” is specified in Output Control. If there is no Output Control option and PRINT_CONCENTRATION is specified, then concentration are printed for the last time step of each stress period.
  • print_flows (boolean) –
    • print_flows (boolean) keyword to indicate that the list of lake flow rates will be printed to the listing file for every stress period time step in which “BUDGET PRINT” is specified in Output Control. If there is no Output Control option and “PRINT_FLOWS” is specified, then flow rates are printed for the last time step of each stress period.
  • save_flows (boolean) –
    • save_flows (boolean) keyword to indicate that lake flow terms will be written to the file specified with “BUDGET FILEOUT” in Output Control.
  • concentration_filerecord ([concfile]) –
    • concfile (string) name of the binary output file to write concentration information.
  • budget_filerecord ([budgetfile]) –
    • budgetfile (string) name of the binary output file to write budget information.
  • timeseries ({varname:data} or timeseries data) –
    • Contains data for the ts package. Data can be stored in a dictionary containing data for the ts package with variable names as keys and package data as values. Data just for the timeseries variable is also acceptable. See ts package documentation for more information.
  • observations ({varname:data} or continuous data) –
    • Contains data for the obs package. Data can be stored in a dictionary containing data for the obs package with variable names as keys and package data as values. Data just for the observations variable is also acceptable. See obs package documentation for more information.
  • packagedata ([lakeno, strt, aux, boundname]) –
    • lakeno (integer) integer value that defines the lake number associated with the specified PACKAGEDATA data on the line. LAKENO must be greater than zero and less than or equal to NLAKES. Lake information must be specified for every lake or the program will terminate with an error. The program will also terminate with an error if information for a lake is specified more than once. This argument is an index variable, which means that it should be treated as zero-based when working with FloPy and Python. Flopy will automatically subtract one when loading index variables and add one when writing index variables.
    • strt (double) real value that defines the starting concentration for the lake.
    • aux (double) represents the values of the auxiliary variables for each lake. The values of auxiliary variables must be present for each lake. The values must be specified in the order of the auxiliary variables specified in the OPTIONS block. If the package supports time series and the Options block includes a TIMESERIESFILE entry (see the “Time-Variable Input” section), values can be obtained from a time series by entering the time-series name in place of a numeric value.
    • boundname (string) name of the lake cell. BOUNDNAME is an ASCII character variable that can contain as many as 40 characters. If BOUNDNAME contains spaces in it, then the entire name must be enclosed within single quotes.
  • lakeperioddata ([lakeno, laksetting]) –
    • lakeno (integer) integer value that defines the lake number associated with the specified PERIOD data on the line. LAKENO must be greater than zero and less than or equal to NLAKES. This argument is an index variable, which means that it should be treated as zero- based when working with FloPy and Python. Flopy will automatically subtract one when loading index variables and add one when writing index variables.
    • laksetting (keystring) line of information that is parsed into a keyword and values. Keyword values that can be used to start the LAKSETTING string include: STATUS, CONCENTRATION, RAINFALL, EVAPORATION, RUNOFF, and AUXILIARY. These settings are used to assign the concentration of associated with the corresponding flow terms. Concentrations cannot be specified for all flow terms. For example, the Lake Package supports a “WITHDRAWAL” flow term. If this withdrawal term is active, then water will be withdrawn from the lake at the calculated concentration of the lake.
      status : [string]
      • status (string) keyword option to define lake status. STATUS can be ACTIVE, INACTIVE, or CONSTANT. By default, STATUS is ACTIVE, which means that concentration will be calculated for the lake. If a lake is inactive, then there will be no solute mass fluxes into or out of the lake and the inactive value will be written for the lake concentration. If a lake is constant, then the concentration for the lake will be fixed at the user specified value.
      concentration : [string]
      • concentration (string) real or character value that defines the concentration for the lake. The specified CONCENTRATION is only applied if the lake is a constant concentration lake. If the Options block includes a TIMESERIESFILE entry (see the “Time-Variable Input” section), values can be obtained from a time series by entering the time-series name in place of a numeric value.
      rainfall : [string]
      • rainfall (string) real or character value that defines the rainfall solute concentration \((ML^{-3})\) for the lake. If the Options block includes a TIMESERIESFILE entry (see the “Time-Variable Input” section), values can be obtained from a time series by entering the time-series name in place of a numeric value.
      evaporation : [string]
      • evaporation (string) real or character value that defines the concentration of evaporated water \((ML^{-3})\) for the lake. If this concentration value is larger than the simulated concentration in the lake, then the evaporated water will be removed at the same concentration as the lake. If the Options block includes a TIMESERIESFILE entry (see the “Time-Variable Input” section), values can be obtained from a time series by entering the time-series name in place of a numeric value.
      runoff : [string]
      • runoff (string) real or character value that defines the concentration of runoff \((ML^{-3})\) for the lake. Value must be greater than or equal to zero. If the Options block includes a TIMESERIESFILE entry (see the “Time-Variable Input” section), values can be obtained from a time series by entering the time-series name in place of a numeric value.
      ext_inflow : [string]
      • ext-inflow (string) real or character value that defines the concentration of external inflow \((ML^{-3})\) for the lake. Value must be greater than or equal to zero. If the Options block includes a TIMESERIESFILE entry (see the “Time- Variable Input” section), values can be obtained from a time series by entering the time-series name in place of a numeric value.
      auxiliaryrecord : [auxname, auxval]
      • auxname (string) name for the auxiliary variable to be assigned AUXVAL. AUXNAME must match one of the auxiliary variable names defined in the OPTIONS block. If AUXNAME does not match one of the auxiliary variable names defined in the OPTIONS block the data are ignored.
      • auxval (double) value for the auxiliary variable. If the Options block includes a TIMESERIESFILE entry (see the “Time- Variable Input” section), values can be obtained from a time series by entering the time-series name in place of a numeric value.
  • filename (String) – File name for this package.
  • pname (String) – Package name for this package.
  • parent_file (MFPackage) – Parent package file that references this package. Only needed for utility packages (mfutl*). For example, mfutllaktab package must have a mfgwflak package parent_file.
