New boundary conditions
The width of the inlet is equal to
the width of the minor bed :
New results
Here correction on inlet boundary can be noticed, in fact there still flow in the inlet, but this is not the steady state :
new results after after 650s with a time step of 4 sec with is obviously too large :
above left : velocity vector at 650 sec
above right : water height at 50 sec
other : water height at 50 sec and 650 sec
