Line 38: !colspan="2" \| Tabular Check Files \|- \| [[Check_Files_2d_bc_tables \| _2d_bc_tables_check]]\|\| Tabular data as read from the boundary condition database via any 2d_bc layers and after any adjustments (ege.g. time shift). Provides traceability to original data source. '''Note: the boundary values do not include the effects of any 2d_bc attributes such as f.''' \|- !colspan="2" \| Raster Check Files Line 67: \| [[Check_Files_2d_glo \| _glo_check]]\|\| GIS layer of any gauge level output (GLO) locations. \|- \| [[Check_Files_2d_grd \| _grd_check]]\|\| GIS layer of the final 2D grid. Represents the final grid including modifications from the .tgc file, boundary specifications and flow constrictions. Note that the Material and bed resistance (ege.g. Mannings_n) attributes do not include any modifications due to flow constrictions as these are applied directly to the cell mid-sides (rather than the cell centre). To view these use the [[Check_Files_2d_uvpt\|_uvpt_check]] file.<br> Can also be written at different stages within a .tgc file (see <font color="blue"><tt>Write GIS Grid </tt></font> <font color="red"><tt>==</tt></font> command). The file contains all modifications to the 2D grid at the point in the .tgc file that it is written. <br> Note that a number of additional attributes are appended to the_grd_check layer when some features of TUFLOW have been used. Line 127: Any generated pit channels are shown as a small channel flowing from north to south into the pit node. The upstream pit channel node that is generated is also shown. The length of the pit channel is controlled by <font color="blue"><tt>Pit Channel Offset </tt></font> <font color="red"><tt>==</tt></font> command. \|- \| [[Check_Files_1d_nwk_N \| _nwk_N_check]]\|\| GIS layer of the final 1D model network. ~~This~~ ~~check layer contains the nodes of the 1D domain only. The _nwk_C_check layer contains the channels.~~<br> '''This is very useful for checking for channel ends or nodes that are not snapped.'''<br> \|- \| [[ Check_Files_1d_pit_A \|_pit_A_check]]\|\| GIS layer of the 1D pit details. \|- \| [[Check_Files_1d_WLLo \| _WLLo_check<br>_xWLLo_check]]\|\| GIS layer of all the WLL objects read. The attributes provide information on which nodes ~~that~~and ~~area~~channels are ~~associated~~upstream ~~with~~or downstream, hence provide an information on the network, etc. <br> The _WLLo_check layers are written for ESTRY 1D domains, whereas the _xWLLo_check layers are written for external 1D domains, such as Flood Modeller or XP-SWMM. \|-
