i am trying to create a scenario in which there are two inflow at a junction and two outflow from the junction . is it possible ? while creating such scenario hec-ras say this is not possible.
I’m not completely sure but junction has only 3 reaches. To solve your problem you can create a dummy reach between two junctions. In the US juction you will have the 2 inflow plus dummy reach, in the DS junction you will have the dummy reach and the 2 outflow. To define the dummy reach you can use 2 XS very close.
