Line 51: *Specifying SXL for the ‘Conn_2D’ attribute automatically creates a 2D SX connection at the 2D cell within which the 1D pit is located. In addition, the ZC elevation of the cell will be lowered by the amount specified in the ‘US_Invert’ attribute (0.1m), and the upstream invert of the pit channel set to the lowered 2D cell elevation. This is useful to help trap the water into the pit as it flows overland in the 2D domain. <br> <br> <li> Open the layer ~~'''~~'''1d_x1d_FMT_M01_nwk_001''' created in [[Flood_Modeller_Tutorial_Module01 \| Flood Modeller Tutorial 1]]. Note that the pipe network has been digitised to outfall to the watercourse. We will manually specify the downstream invert levels of Pipe16 and Pipe18 as the discharge point of the pipe network is above the bed level of the watercourse. Use the Info tool and click on each pipe in turn and change the ‘DS_Invert’ attribute for both pipes from -99,999 to 38m. <li>Save both '''1d_nwk_FMT_M02_Pipes_001''' and '''1d_nwk_FMT_M02_Pits_001''' and export to MID/MIF format. </li><br> <u>'''Pit Inlet Database'''</u>
