Model Underdrain in Pond Pack v.10

[mddeng]

Hello, the project I am working on consists of a number of LID BMPs (raingardens, swales, an underground storage system, and porous paving).

The BMPs operate in a series raingarden>stormtech, porous paving>stormtech, etc.

I'm using 3' of stone under the porous, along with a 4" perforated HDPE underdrain, which discharges to the storm tech, in addition to the on-site infiltration.

I'm not quite sure how to set the underdrain as the outlet for the stone bed under the porous. HydroCAD does this very easily, but I'm looking for ideas on how to do this in Pondpack.

Thanks in advance.

Can you input a manual rating curve in Pondpack? If so, that'd be your worst case fallback. Do it in excel and import it in tabular format. I've done that in XP-SWMM before.
