Hello everyone,

I'm a beginer with Mascaret. I'm trying to model simple cases studies with one reach, discharge as boundary condition upstream and water level as boundary condition downstream but when I run the models, the Mascaret listing indicates:

"Error n°1"
"Error of calculation: the section 11 is dry"

Or

"Error 40"
"Error of calculation: the wetted perimeter is negative or zero"

When I look at the results, the discharge is zero even though I entered a value for the discharge. Why do I have these error message?

Thanks in advance for your help.

Naomi	Hello, I used the "permanent" kernel.
