Reply To: Fatal error – slope < 0.00

[Benson Liu]

Hi Osta,

0.003% is a very flat slope and ArcRORB normally gives you a warning when you try and export reaches with such a flat slope. When such flat slopes are input into RORB for type 2 and 3 reaches, RORB will cap the slope to be 0.05%.

RORB is supposed to still work fine but just sets the slope to be 0.05% so this error is a bit odd. Does it disappear if the flattest slope is 0.05%? If the error is still there can you upload your catg file and I will take a look.

Kind regards,

Benson
