Hello, i'm sort of new to OpenRoads but have used StormCAD before.
I have created a User Defined IDF Table for the location of my project. In my Alternatives, I've created a Base Rainfall Runoff Child Alternative for each frequency I'm interested in. In my drawing I've delineated a catchment, assigned an outflow element, and assigned a Rational Coefficient. In the Base Analysis Scenario, the Rainfall Runoff is set the child Alternative.
Perhaps I'm missing some steps, because when I compute, I don't get any flow from the catchment? Please help.
Check Tc in the catchment.
I have occasionally found that even though I chose an outflow element while making the catchment that after review the outflow is set to none. So, double check the outflow element.
