Tc for upstream pipes into catch basins
Tc for upstream pipes into catch basins
(OP)
when i model catchbasins i typically use the "catch basin" type of pond, and model the outlet as the down stream connecting culvert.
How do I "take advantage of the Tc" of the outlet (downstream) culvert as it traverses across my next downstream subatchment?
In other words... I am wondering if the outlet culvert of a catchbasin pond should be included as a Tc segment in the next downstream subcatchment?
But that would artificially increase the length of the Tc run!
By modeling the outlet pipes of catchbasins, are my outlet pipes correctly delivering the pipe flow to the next pond?

Also, try to keep the model as simple as possible in order to meet your specific analysis objectives. Don't include components that don't need to be in the model. For general guidelines please see www.hydrocad.net/howto.htm
