The table below highlights some of the commonly used check files when reviewing 1D bridges. The full list of TUFLOW check files can be found [[TUFLOW_Check_Files | here]].

! style="background-color:#005581; font-weight:bold; color:white;" width=75%| Brief Description
|-
| [[Check_Files_1d_bc_tables | _1d_bc_tables_check.csv]]|| Contains the inverts of the 1D nodes and at the ends of the 1D channels. Very useful for checking for smooth transitions from one channel to another and with the nodes.
|-
| [[Check_Files_1d_ta_tables | 1d_ta_tables_check.csv]]|| Tabular data as read from tables via the 1d_tab layers for cross-section, storage and other data. Provides full traceability to original data source and additional information such as hydraulic properties determined from a cross-section profile. Flood Modeller XZ processed, and MIKE 11 processed cross-section data included. Refer also to the _xsl_check layer.
|-
| [[Check_Files_1d_hydroprop | _hydroprop_check.mif<br>_hydroprop_check_L.shp]]|| Contains the hydraulic properties at the top of the hydraulic properties tables as attributes of the 1D channels. Other information such as the primary Manning’s n is also provided. Very useful for carrying out quality control checks on the 1D channels.
|-
| [[Check_Files_1d_inverts | _inverts_check.mif<br>_inverts_check_P.shp]]|| Contains the inverts of the 1D nodes and at the ends of the 1D channels. Very useful for checking for smooth transitions from one channel to another and with the nodes.
|-
| [[Check_Files_1d_IWL | _iwl_check.mif<br>_iwl_check_P.shp]]|| GIS .mif/.mid or .shp files of the initial water levels at the 1D model nodes.
|-
| [[Check_Files_1d_nwk_C | _nwk_C_check.mif<br>_nwk_C_check_L.shp]]|| GIS .mif/.mid or .shp files of the final 1D model network. This check layer contains the channels of the 1D domain only. The _nwk_N_check layer contains the nodes.<br>
The layers lines are coloured based on the channel type (available for the .mid/.mif format only).<br>
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 <tt>Pit Channel Offset == </tt> command.
|-
| [[Check_Files_1d_nwk_N | _nwk_N_check.mif<br>_nwk_N_check_P.shp]]|| GIS .mif/.mid or .shp files 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>
The node symbology is displayed as a red circle for nodes connected to two or more channels, a larger magenta circle for nodes connected to one channel and a large yellow square for nodes not connected to a channel (available for the .mid/.mif format only). '''This is very useful for checking for channel ends or nodes that are not snapped.'''<br>
The top and bottom elevations of the NA table at nodes is now shown using the Upstream_Invert and Downstream_Invert attributes.
|-
| [[Check_Files_1d_xsl | _xsl_check.mif<br>_xsl_check_L.shp]]|| GIS layer containing tabular data as read from 1d_xs input layers. Contains the XS ID and other useful information on the cross-section properties, etc. Refer also to [[Check_Files_1d_ta_tables | _ta_tables_check.csv]].
