= Common Questions Answered (FAQ)=
== My cross sections have various Manning's ''n'', but only one value is reported in 1d_ta_tables_check.csv. Is it applied correctly? ==
When the Manning’s ''n'' values differ throughout the cross section (N flag is specified), these are used to proportionally adjust the width of the cross section to an effective width and calculate the whole cross section as it has only one Manning’s ''n''. In the processed hydraulic properties part of the 1d_ta_tables_check.csv, the width is different to the effective width and the header of the last column K (conveyance) only shows a single Manning’s ''n'' value. The .eof file and nwk_C_check file will report one Manning's ''n'' and n_nf_cd value, the one that was used for the calculation of the effective width - bed elevation Manning's ''n''.<br>
Note: When an N flag is specified in XZ cross section, the n_nf_cd value in 1d_nwk layer becomes a Manning's ''n'' multiplier. It is usually set to 1 and could be used for calibration purposes.<br>
