Culverts issue #277
Description
Hi everyone, I am trying to modelling some stuff with the Anuga's culvert operator. I use the box operator with a rectangular section 10m * 1m. The problem is that the flow rate is lower than what expected either if the culvert is gravity led or under pressure.
The amount of water expected, infact, is something like 100 m^3/2 (calculated with the uniform flow formula) while the value calculated by the culvert operator is about 50 m^3/s. I have tryed also to use e pipe culvert operator, instead the box operator, but the flow rate decrease to 40 m^/s.
NB: I use the operator with two points (start and end) and not with two lines.
