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

<li>The Pit Inlet Database has been created and can be found within '''Module_data\Module_02\Pipe_Network'''. Copy the csv files '''pit_inlet_curves.csv''' and '''pit_inlet_dbase.csv''' into a new folder entitled '''pit_dbase''' within the TUFLOW folder.
<li>Open the '''pit_inlet_dbase.csv''' file. The Pit Inlet Database is similar to the Boundary Condition Database in that it references an external source file and relates this to corresponding GIS objects within the model. <br>
The first column contains the name of pit inlet type as referenced in the Inlet_Type attribute that was specified within the '''1d_nwk_FMT_M02_Pits_001_P''' layer. The second column contains the name of the source .csv file that contains the depth-discharge curve. The third and fourth columns are the heading labels of the depth and discharge columns respectively in the source .csv file. The fifth and sixth columns are the inlet’s nominated full flow area in m<sup>2</sup> and flow width in m.

1d_nwk layers have been created representing the conduits and pits that make the pipe network that of the proposed development. The layers have made use of an automated function to link the pits to the 2D domain to allow for the exchange of water between the pipe network and the floodplain. A Pit Inlet Database has been created to define a depth-discharge relationship at each pit. Please return to the main page of the[[
