I am doing a flood study of a bridge. I am modeling the main channel of the river as 1D and the rest of the area using 2D. I connect the 1D with the 2D using a lateral structure but when I run the program, the water is only distributed along the 1D zone although it should extent to the 2D area too.
Any idea why the lateral structure connection is not working properly?
How did you make the connection? Be sure that in Tailwater Connection you connected to the 2D area, if it’s set to “out of the system” then the 2D area will receive no flow.
