==Pit Search Distance==
Line 165 ⟶ 167:
The order of the "Pit Search Distance" command is important as it can be repeated multiple times with different values that are assigned to the 1d_nwke(s) below the ''Pit Search Distance'' command. The pit search command should be included above the the GIS layer containing the pits.
To check if the ''Pit Search Distance'' is working as expected, import the <u>[[Check_Files_1d_nwk_C | *_nwk_C_check]]</u> file to visually see if the pits are automatically connecting to a culvert. The image below is an example of the *_nwk_C_check file and the connections TUFLOW has made to each pit. <br>
