The attributes are described completely in
*The 1d_nwk type. In this case, we have specified culverts with a circular shape.
*The Manning’s n value of the culvert.

Note that although the same layer (1d_nwk) has been used to define the pits of the pipe network as for the culverts, different attributes have been populated. Refer to
<u>[https://docs.tuflow.com/classic-hpc/manual/2025.1/OneD-Domains-1.html#tab:tab-CulvertsAttributeDescriptions Table 5.5]</u> and <u>[https://docs.tuflow.com/classic-hpc/manual/2025.1/OneD-Domains-1.html#tab:tab-PitsModelNetwork Table 5.24]</u> of the TUFLOW Manual for further information on how the attributes of the 1d_nwk layer differ between nodes and channels. The attributes that we have populated for the pits, define:<br>
*The type of pit channel. In this case, a type ‘Q’ specifies the flow is to be defined by a depth-discharge curve from a user defined database. This database will be created in the next steps of this module.
*AB is the name of the pit inlet type referenced within the pit database.
