This file is only created if a source area (2d_sa, 2d_sa_rf, 2d_sa_po or 2d_sa_tr) GIS layer has been specified in the model (Read GIS SA [ <option> ] == ). This file contains information on the lowest, stream or pit cells for each SA boundary region.

Attributes of _sac_check

Attribute Name Attribute Description
BC_Description This contains a description of the type of cell (lowest, stream or pit), the boundary name and the number of cells this applies to. An example is:

Lowest 2D cell for Inflow "SB1" (ZC = 44.06; No. Cells = 1546)

This indicates that the cell is "lowest", the source boundary name is "SB1" and the minimum cell elevation is 44.06 and a total number of cells within the SA region is 1546.
Refer to the TUFLOW Manual for more information on the different source area boundaries.

BC_Name The source boundary name, e.g. "SB1".
BC_Group If using boundary groups, this is the boundary group. If boundary groups are not used, this attribute will be blank.

The image below shows a _sac_check file, styled using default TUFLOW styling and labeled by source boundary name.



The image below shows a _sac_check file for a model using pits (Read GIS SA PITS == ). The _sac_check has been styled based on the source boundary name. The input 2d_sa (styled using default TUFLOW styling) GIS layer has been included.



The image below shows a _sac_check file for a model containing streamlines (2d_strm). The _sac_check has been styled based on the source boundary name. The input 2d_strm (styled in black) and 2d_sa (styled using default TUFLOW styling) GIS layers have been included.
