[docs]class Drainage(BoundaryCondition): """ The Drain package is used to simulate head-dependent flux boundaries. https://water.usgs.gov/ogw/modflow/mf6io.pdf#page=67 Parameters ---------- elevation: array of floats (xr.DataArray) elevation of the drain. (elev) conductance: array of floats (xr.DataArray) is the conductance of the drain. (cond) concentration: array of floats (xr.DataArray, optional) if this flow package is used in simulations also involving transport, then this array is used as the concentration for inflow over this boundary. concentration_boundary_type: ({"AUX", "AUXMIXED"}, optional) if this flow package is used in simulations also involving transport, then this keyword specifies how outflow over this boundary is computed. print_input: ({True, False}, optional) keyword to indicate that the list of drain information will be written to the listing file immediately after it is read. Default is False. print_flows: ({True, False}, optional) Indicates that the list of drain 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. Default is False. save_flows: ({True, False}, optional) Indicates that drain flow terms will be written to the file specified with "BUDGET FILEOUT" in Output Control. Default is False. observations: [Not yet supported.] Default is None.
