Sag Gutter Overflow Condiditons

[rdbrennan48]

Is anyone aware of a way to define a emergency overflow elevation to a intake at a sag point. I would like to find a way to accuratly route the 100yr storms through a model containing both my storm sewer and detention models.

Any help or comments would be appriciated thanks

Storm Sewers does have a local depression option in the gutter flow.

Will that work?

Also the Hydraflow does allow to divert by structure.  Insert 2 blank rows below the hydrograph you want to split, then select the inflow hydrograph then the divert icon on the right.  You should be able to divert by one of the outfall structures.

I use this frequently to diver by infiltration for the NPDES volume calculations.

I haven't used SSA yet.

Could you define a weir with the crest elevation set to the emergency overflow elevation and link it to intake at the sag point?

I was hoping that there was a better way to do it but that does work. I have to set the rim elevation of the intake 1-2 ft higher depending the vrest elevation of the weir. I wish there was a way to make that work so you can maintain the import and export properties with CAD.
