Line 48:
<li> Import an empty 1d_nwk GIS file from the TUFLOW file template folder (model\gis\empty).
<li> Digitise points to represent pit locations. The points should be snapped to the start or end of 1d_nwk line features that define the underground pipe network.
<li> Update the field attributes for each Pit point. Refer to 5.12.2 of the 2016 TUFLOW Manual. The most commonly used attributes are:
* Type = Q (C, R and W are also options if pit inlets based on structure dimension is required instead of using a Pit Inlet Database approach).
* US_Invert = Used to specify the ground elevation of the pit. If Conn_1D_2D is set to “SXL”, US_Invert is used as the amount by which to lower the 2D cell and the pit channel invert is set to this level.
