Line 103:
This file defines the centerline of the channel. This centerline data can be split using the cross-section data to define the 1D channel (1d_nwk) in a TUFLOW model. The following field attributes should be used if this check file is converted into a TUFLOW input:
<ol>
<li>"Len_or_ANA"= 0 (the length of the line/polyline is used).
<li>"n_or_n_F" = 1 (materials are being defined in the cross-section csv files. n_or_n_F is a multiplication factor of the cross-section manning’s n value).
<li>"US_Invert"= -99999 (the bed of the channel cross-section is used).
<li>"DS_Invert"= -99999 (the bed of the channel cross-section is used).
</ol>
<li> ''<sdf_filename>_cut_line'': <br>
Echo of the cross-section line (non-trimmed).
<li> ''<sdf_filename>_levee_pts'': <br>
Points defining the intersection of the cross-section line with the levee used to trim the cross-section dataset.
<li> ''<sdf_filename>_surf_line'': <br>
Point dataset reporting the location of each elevation values within the csv cross-section dataset.
