In SSA... We would be glad for any input as to the best way to model sag inlet overtopping flows.
In our example:
A subbasin is routed to a sag inlet. Sag inlet "A" does not have enough capacity to handle the entire runoff from subbasin. Water in reality will overtop at a highpoint in the parking lot (weir in the model) and route to the GRATE of another inlet "B". We would prefer (in some cases we need) to do all this with hydrodynamic routing options (not kinematic wave).
Any tips?
Thank you!

I would suggset you have a small storage area with an horizontal orifice (your inlet), and a weir bypass.
