The Lake Transport (LKT) Package dialog is accessed by double-clicking on the LKT package under a MODFLOW 6 simulation in the Project Explorer. It contains the following sections and options:
- Sections list – A list of sections that can be turned on or off:
- COMMENTS – Turn on to make the COMMENTS section visible.
- OPTIONS – Turn on to make the OPTIONS section visible.
- DATA – Turn on to make the DATA section visible.
- COMMENTS section – Enter general alphanumeric comments. Comments entered here get written at the top of the file, preceded by a '#' symbol.
- OPTIONS section – Options and settings:
- FLOW_PACKAGE_NAME – This allows the name of the corresponding flow package to be specified. Turning this on will activate a textbox to the right where this can be entered. If this isn't specified, then the corresponding flow package will need to have the same name as this advanced transport package (the name associated with this package in the GWT name file).
- AUXILIARY – This allows an array of one or more auxiliary variables to be named. There are no limits to the number of auxiliary variables that can be provided, but subsequent blocks will require data for each of the auxiliary variables that are defined. Turning this on will activate an Auxiliary Variables... button. Clicking the button will bring up an Auxiliary Variables dialog.
- FLOW_PACKAGE_AUXILIARY_NAME – This allows the name of an auxiliary variable in the corresponding flow package to be specified. Turning this on will activate a textbox to the right where this can be entered. If this is specified, then this advanced transport package's simulated concentrations will be copied into the auxiliary variable specified with the entered name. If the flow package does not have an auxiliary variable with this name, then the program will terminate with an error. This option will have no effect if the flows for this advanced transport package are read from a file.
- BOUNDNAMES – This indicates that boundary names are allowed to be provided with the list of lake cells. This will add the BOUNDNAME column to the spreadsheet in the DATA section.
- PRINT_INPUT – This indicates that the list of lake information input will be printed to the listing file immediately after it is read.
- PRINT_CONCENTRATION – This indicates that the list of lake concentration will be printed to the listing file, for every stress period where “HEAD PRINT” has been specified in Output Control. If PRINT_CONCENTRATION has been specified when there is no Output Control option, then they will be printed for the last time step of each stress period.
- PRINT_FLOWS – This indicates that the list of lake flow rates will be printed to the listing file, for every stress period time step where “BUDGET PRINT” has been specified in Output Control. If PRINT_FLOWS has been specified when there is no Output Control option, then they will be printed for the last time step of each stress period.
- SAVE_FLOWS – This indicates that lake flow terms will be saved to a budget file (specified in Output Control with "BUDGET FILEOUT").
- CONCENTRATION FILEOUT – This allows concentration information to be saved to a specifically defined binary output file.
- BUDGET FILEOUT – This allows budget information to be saved to a specifically defined binary output file.
- TS6 FILEIN – This allows time series files to be used as input to assign time-varying values. Specifying this option will allow a Files... button to its right to be clicked. Doing so will bring up a Files dialog.
- OBS6 FILEIN – This allows observations files to be used as input. Specifying this option will allow a Files... button to its right to be clicked. Doing so will bring up a Files dialog.
- DATA section – This deals with the DATA block.
- PACKAGEDATA – This deals with the PACKAGEDATA block.
- Set Up From LAK6 Package – This button allows for PACKAGEDATA to be set up from an already existing LAK6 Package. If one cannot be found, a warning dialog will come up saying so.
- Add Rows... – This button brings up a Rows to Add dialog, where a number can be specified to the right of Number of rows to add at bottom. This will help populate the spreadsheet.
- LAKENO – This column represents the LAKENO integer values, which define the lake numbers associated with the PACKAGEDATA data. These values must be greater than zero and less than or equal to the separately defined NLAKES value. If lake information has not been specified for every lake or information for a lake has been specified more than once, the program will terminate with an error.
- STRT – This column represents the STRT real values, which define the starting concentration for the lakes.
- AUX – These columns represent the values of the auxiliary variables for each lake, which previously may have been created if the AUXILIARY option was set. There will need to be values for the auxiliary variables for each lake. If time series files are used as input, entering a time series name instead of a numeric value can allow for values to be obtained from a time series.
- BOUNDNAME – This column represents the names of the lake cells, and will appear if the BOUNDNAMES option was set. BOUNDNAME values are ASCII character variables that can contain as many as 40 characters. If a BOUNDNAME value contains spaces within it, then the entire name will have to be enclosed within single quotes.
- PERIODS – This deals with the PERIODS block.
- Period – A numeric updown can be used to enter which period is being examined in the spreadsheet.
- Define Period – This button will allow a period to be defined. This will be active when no period has yet been defined, and it may gray out once one has been created.
- Delete Period – This button will delete the selected period. A dialog warning will come up first asking the user to confirm their decision to delete the period.
- Add Rows – This button will bring up an Add Stresses dialog.
- Delete Rows – This button will delete all of the stresses. A dialog warning will come up first asking the user to confirm their decision to delete the stresses. The dialog will also give them the option to either Delete From All Periods or Delete From Just This Period.
- Plot All Periods – This will allow the user to plot all the periods that have been defined.
- Open Time Series – This will allow the user to open a time series file.
- Filter on Selected Cells – If UGrid cells are selected when the dialog is opened, this button causes the table to only display those rows that correspond to the selected cells.
- LAKENO – This column represents the LAKENO integer values, which define the lake numbers associated with the PERIOD data. These values must be greater than zero and less than or equal to the separately defined NLAKES value.
- LAKSETTING – This column represents the LAKSETTING keywords, which can be used to start LAKSETTING strings (lines of information parsed into a keyword and values). These are used to assign the concentration associated with the corresponding flow terms. Concentrations cannot be specified for all flow terms (ex. The Lake Package supports a "WITHDRAWAL" flow term. If this is active, water will be withdrawn from the lake at its calculated concentration.). These keywords are assigned in a drop-down, which can be selected to one of the following options:
- "STATUS" – This keyword option is used to define lake status. The STATUS options are:
- "ACTIVE" – The default value is "ACTIVE", which means the concentration will be calculated for the lake.
- "INACTIVE" – If the value has been set to "INACTIVE", then there will be no solute mass fluxes into/out of the lake and the inactive value will be written for the lake concentration.
- "CONSTANT" – If the value has been set to "CONSTANT", then the concentration for the lake will be fixed at the user-specified value.
- "CONCENTRATION" – This keyword option uses a real/character value to define the concentration for the lake. The specified value will only be applied for constant concentration lakes. If time series files are used as input, entering a time series name instead of a numeric value can allow for values to be obtained from a time series.
- "RAINFALL" – This keyword option uses a real/character value to define the rainfall solute concentration (ML-3) for the lake. If time series files are used as input, entering a time series name instead of a numeric value can allow for values to be obtained from a time series.
- "EVAPORATION" – This keyword option uses a real/character value to define the concentration of evaporated water (ML-3) for the lake. When this value is larger than the simulated concentration in the lake, then evaporated water will be removed at the same concentration as the lake. If time series files are used as input, entering a time series name instead of a numeric value can allow for values to be obtained from a time series.
- "RUNOFF" – This keyword option uses a real/character value to define the concentration of runoff (ML-3) for the lake. This value will need to be greater than or equal to zero. If time series files are used as input, entering a time series name instead of a numeric value can allow for values to be obtained from a time series.
- "AUXILIARY" – This keyword option is used to specify auxiliary variables, and will require two values to be properly used. The first value will be for the AUXNAME, the name for the auxiliary variable that will be assigned an AUXVAL. This AUXNAME will need to match one of the names that was previously defined for the auxiliary variables in the OPTIONS section. If it does not, the entered data will be ignored. The second value will be for the AUXVAL, the value for the auxiliary variable that was named. If time series files are used as input, entering a time series name instead of a numeric value can allow for values to be obtained from a time series.
- "STATUS" – This keyword option is used to define lake status. The STATUS options are:
- VALUE1 – This column is for the first value following the keyword specified in the LAKSETTING column. For most keywords, only this column will be needed.
- VALUE2 – This column is for the second value following the keyword specified in the LAKSETTING column. Only "AUXILIARY" requires this, as the first value will be an AUXNAME and the second value will be an AUXVAL.
- PACKAGEDATA – This deals with the PACKAGEDATA block.
