Modeling a Skimmer or Floating Outlet
If the device flow is subject to significant variation with head, more precise modeling can be obtained by entering the exact rating curve with a special outlet device. HydroCAD also includes a library of predefined rating curves, making it even easier to model any of the supported product. |

Certain outlet control devices are designed to float on the surface of a
pond, such that a constant head is maintained over a weir or orifice, resulting
in a relatively constant discharge regardless of water surface elevation. These
devices are easily modeled by using the "Constant Flow/Skimmer" outlet
added in
HydroCAD-10. This option also allows the user to specify the "phase-in
depth" that is required for the full design flow to be achieved.
