open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi everyone

More than a problem, I have a doubt regarding my results, I have a bifurcation of channels, slope in all sections of 0.25%, manning coefficient of 0.011, flow of 40 L / s and occurs that in some sections occur hydraulic jump, To me it seems very strange, since, the whole section is smooth slope.

I have tried to explain how this could happen and I can not find an explanation.

Also, I made a run with finite volumes and the same thing happens.

It would be of great help, if someone could give me an idea of ​​why this phenomenon.
