Pond Outlet Structure

Pond Outlet Structure

Pond Outlet Structure

How to model a structure with an inlet pipe(submerged) A weir wall inside the structure with an orifice in it.  A rim to the structure and an outlet pipe.  Have any ideas about to go about doing that?

RE: Pond Outlet Structure

If I understand your description correctly I would model as follows:

Pond 1->outlet culvert(inlet pipe)->Pond 2(This is the structure using pond type "Catch Basin with insignificant storage"

Pond 2 is configured as follows (using made-up dimensions):

#  Routing   Invert  Outlet Devices
1  Primary   50.00   24" x 100'long Outlet pipe
2  Device 1  50.10   3.0" Vert.Orifice in Weir Wall
3  Device 1  52.00   2.0'x 2.0' high Sharp Crested Rect. Weir
4  Device 1  55.00   48" Horiz. Structure Top (Rim)

RE: Pond Outlet Structure

TerryScan's solution makes sense, with the rim overflow modeled as a horizontal orifice.  However, since the overflow doesn't pass through the culvert, it should be routed directly to primary or secondary, depending on the downstream routing.

This situation also points out that HydroCAD doesn't deal with inlet restrictions as such.  All restrictions are modeled as outlet controls on the appropriate "pond", hence TerryScan's recommendation of two ponds in series.
