The proposed storm drain system connects into an existing system in my project design. I am modeling the proposed, and using an outfall at the connection to the existing system (I would prefer not to model the existing system as it is large and cumbersome). I would like my boundary condition to reflect a predetermined elevation, but I am having trouble adjusting the starting water surface elevation. I have tried using a fixed elevation or a time series function, but the boundary condition won’t adjust above the unimpeded normal depth.
i am pretty sure i have experienced similar problem (sorry, not in front of computer, but will look up a recently done model and re-confirm tomorrow with some relevant screenshots). can anyone shed some light into this, as to why SSA is not honoring a specified tailwater boundary condition? SSA version 2011.
Hi,
Have you tried setting the Link Routing Method in the Project Options dialog to Hydrodynamic? I think setting the routing method to “Hydrodynamic” will honor the boundary condition of defined WSEL.
Thank you,
