|tuflow_message=WARNING 1262 - Manning's n value of ",a,"<Manning's n value> for channel ",a,"<Channel ID> is unusually low or high.

|message_desc=Manning's n value assigned to channel, is outside normal range.

|suggestions=Check Manning's n value for channel. If material values are defined in the XZ cross-section ("M" flag), the n_or_n_F attribute in the 1d_nwk is a multiplication factor and should be set to 1 (this may be adjusted as part of the calibration process). This can occur if a the multiplication value is set to a typical ManningsManning's value (e.g. 0.04) and materials are defined in the XZM cross-section. In this case the ManningsManning's n value may become 0.04 x 0.04 = 0.0016!
