Modelling Multiple Ponds in Series
Modelling Multiple Ponds in Series
(OP)
I'm a complete newb here but need to know how to model 2 ponds in series.
The scenario is:
Both ponds have the same bottom elevations and the same top elevations and are connected by a culvert sized to handle the peak CFS with room to spare. The second pond has an orifice outlet.
I am unable to get the ponds to equalize and have the same peak elevation.
I am using HydroCAD 8.00
Any help will be greatly appreciated.
Thanks

RE: Modelling Multiple Ponds in Series
If you need to model them separately, then use a culvert outlet on the first pond, and route the outflow directly to the second pond with the orifice. Pay attention to any warning messages and follow their advice to correct any problems. This will include switching to a tailwater-sensitive routing procedure, such as the dynamic storage-indication method. For details see www.hydrocad.net/dsi.htm
If you still have questions please forward the HydroCAD .HCP file to support@hydrocad.net

If you know that the water level is fairly constant along the length of the pipe (as it is likely to be with equalized ponds) then you could include the pipe storage contribution by adding horizontal cylinder storage to one of the ponds.
