BC Database == <.csv_file>
(Mandatory)
Sets the active BC Database file as described in Sections 3.17.1 and 3.17.2. The file is usually created using spreadsheet software such as Microsoft Excel.
If the BC Database is specified in the TUFLOW .tcf file, it is set as the active database for both 2D and 1D models. However, the active database can be changed at any stage in the .tbc and .ecf files by repeating the command with the new database set as the <.csv_file>.
A BC Database must be specified before any of the other BC commands are used.
BC Event Name ==
(Optional)
Sets the active BC name to be substituted where (see BC Event Text) occurs in the BC Database. See Section 3.17.3 for a description of how the BC event commands operate.
This command is normally specified in the .tcf file, and only used in the .tbc file if the event boundaries vary by event within the model. For example, it may be set to “Q100” to read in the 100 year catchment inflows, then set as “H010” to read in the 10 year ocean levels for the downstream boundary. Note that, in this case, the locations of the catchment inflows and downstream boundaries would have to be placed in two separate GIS layers, with each layer read using Read MI BC after the relevant BC Event Name command as shown below:
BC Event Name == H010
Read MI BC == mi\2d_bc_head_boundaries.mif
BC Event Name == Q100
Read MI BC == mi\2d_bc_flow_boundaries.mif
BC Event Text ==
(Optional)
Sets the text in the BC Database that is to be substituted by the BC Event Name command value. See Section 3.17.3 for a description of how the BC event commands operate.
This command is normally specified in the .tcf file, and only used in the .tbc file if for some reason the value needs to change (this should be very unlikely). Also see BC Event Text for the .tcf file.
Global Rainfall Area Factor == [ {1.0} | ]
(Optional)
Sets the factor applied to the global rainfall after the initial loss and continuing losses have been applied. This is useful if you wish to include catchment area outside the area covered by the water cells.
Global Rainfall BC ==
(Optional)
Sets the BC name in the BC database that defines the global rainfall. The rainfall is specified as mm versus time in hours. This is converted to m/s and applied as a source versus time (ST) boundary to all active (wet) cells. The converted time-series after extraction of any losses (see Global Rainfall Initial Loss and Global Rainfall Continuing Loss) and any area factor (see Global Rainfall Area Factor) is output to the .tlf file (Build 2002-01-AC or later) for checking.
Whilst global rainfall is applied only to wet cells, it is factored up to include any water (Code 1) cells that are dry. The catchment area for global rainfall is therefore all cells with a Code of one (1) (see Section 3.11.1). Use the Global Rainfall Area Factor command to increase the catchment area to include areas not covered by the water cells.
Global Rainfall Continuing Loss == [ {0} | ]
(Optional)
Sets the continuing loss rate in mm/h for any global rainfall.
Global Rainfall Initial Loss == [ {0} | ]
(Optional)
Sets the initial loss in mm for any global rainfall.
Read MI BC == <.mif/.mid_file>
(Mandatory if not using fixed field text entry)
Reads the location and attributes of 2D model boundary conditions as described in Section 3.17.
Read MI SA [ {} | Rainfall ] == <.mif/.mid_file>
(Optional)
Reads the polygons for distributing source flows over the 2D domain(s) as described in Table 4 .24. Usually used for specifying rainfall runoff directly onto the 2D domain(s).
As of Build 2005-05-AN, the Rainfall option is available to specify rainfall hyetographs (mm versus hours) instead of flow hydrographs. See Table 4 .24 for more information noting that this feature is under-development and maybe subject to change at the time of writing.
Unused HX and SX Connections == [ {ERROR} | WARNING ]
(Optional)
See Unused HX and SX Connections under .tcf file commands. The command can be used several times in a .tbc file to change from ERROR to WARNING and vice versa if a different level of checking is required for different 2d_bc layers. When reading and checking a 2d_bc layer, the latest occurrence of this command applies.
