Storm and Sanitary Analysis - Routing a surcharged system

[wesleyd.miller]

Hello,

I am trying to model the following situation using storm and sanitary analysis 2015 (simplified version).

I have a detention pond which has 100 foot of 24 inch pipe outfalling into a catch basin.  That catch basin is the only catch basin on site (only inflow hydrograph).  The water exits the catch basin through a 12" pipe (to decrease discharge).  So basically I am wanting to surcharge my system and force it to back up into the pond and release at an acceptable rate.  This is a simplified version of my problem but if I can model this situation I can model my true design situation.

Thanks for any help, feel free to ask questions for clarification.

It sounds like you are on a perfectly right track, set project options to run hydrodynamic, model the inlet as a functional storage node and connect it with other elements in the system using open channel links or a weir to capture any "bubble ups" (in addition to underground pipe connections), and I think you will be all set.
Good luck!

It appears that simply running as hydrodynamic as oppose to kinematic wave solved the problem. But I will look into your suggestions as well. Thanks for the advice!
