Bases: MFPackage

ModflowGwfmaw defines a MAW package.

Parameters:

  • 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.

  • boundnames (keyword) – keyword to indicate that boundary names may be provided with the list of multi- aquifer well cells.

  • print_input (keyword) – keyword to indicate that the list of multi-aquifer well information will be written to the listing file immediately after it is read.

  • print_head (keyword) – keyword to indicate that the list of multi-aquifer well {#2} 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_{#3} is specified, then {#2} are printed for the last time step of each stress period.

  • print_flows (keyword) – keyword to indicate that the list of multi-aquifer well 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 (keyword) – keyword to indicate that multi-aquifer well flow terms will be written to the file specified with ‘budget fileout’ in output control.

  • head_filerecord ((headfile)) –

    • headfilestring

      name of the binary output file to write head information.

  • budget_filerecord ((budgetfile)) –

    • budgetfilestring

      name of the binary output file to write budget information.

  • budgetcsv_filerecord ((budgetcsvfile)) –

    • budgetcsvfilestring

      name of the comma-separated value (CSV) output file to write budget summary information. A budget summary record will be written to this file for each time step of the simulation.

  • no_well_storage (keyword) – keyword that deactivates inclusion of well storage contributions to the multi- aquifer well package continuity equation.

  • flow_correction (keyword) – keyword that activates flow corrections in cases where the head in a multi- aquifer well is below the bottom of the screen for a connection or the head in a convertible cell connected to a multi-aquifer well is below the cell bottom. when flow corrections are activated, unit head gradients are used to calculate the flow between a multi-aquifer well and a connected gwf cell. by default, flow corrections are not made.

  • flowing_wells (keyword) – keyword that activates the flowing wells option for the multi-aquifer well package.

  • shutdown_theta (double precision) – value that defines the weight applied to discharge rate for wells that limit the water level in a discharging well (defined using the head_limit keyword in the stress period data). shutdown_theta is used to control discharge rate oscillations when the flow rate from the aquifer is less than the specified flow rate from the aquifer to the well. values range between 0.0 and 1.0, and larger values increase the weight (decrease under-relaxation) applied to the well discharge rate. the head_limit option has been included to facilitate backward compatibility with previous versions of modflow but use of the rate_scaling option instead of the head_limit option is recommended. by default, shutdown_theta is 0.7.

  • shutdown_kappa (double precision) – value that defines the weight applied to discharge rate for wells that limit the water level in a discharging well (defined using the head_limit keyword in the stress period data). shutdown_kappa is used to control discharge rate oscillations when the flow rate from the aquifer is less than the specified flow rate from the aquifer to the well. values range between 0.0 and 1.0, and larger values increase the weight applied to the well discharge rate. the head_limit option has been included to facilitate backward compatibility with previous versions of modflow but use of the rate_scaling option instead of the head_limit option is recommended. by default, shutdown_kappa is 0.0001.

  • mfrcsv_filerecord ((mfrcsvfile)) –

    • mfrcsvfilestring

      name of the comma-separated value (CSV) output file to write information about multi-aquifer well extraction or injection rates that have been reduced by the program. Entries are only written if the extraction or injection rates are reduced.

  • timeseries (record ts6 filein ts6_filename) – Contains data for the ts package. Data can be passed as a dictionary to the ts package with variable names as keys and package data as values. Data for the timeseries variable is also acceptable. See ts package documentation for more information.

  • observations (record obs6 filein obs6_filename) – Contains data for the obs package. Data can be passed as a dictionary to the obs package with variable names as keys and package data as values. Data for the observations variable is also acceptable. See obs package documentation for more information.

  • mover (keyword) – keyword to indicate that this instance of the maw package can be used with the water mover (mvr) package. when the mover option is specified, additional memory is allocated within the package to store the available, provided, and received water.

  • nmawwells (integer) – integer value specifying the number of multi-aquifer wells that will be simulated for all stress periods.

  • packagedata ([list]) –

  • connectiondata (list) –

  • perioddata (list) –
