HydroCAD Stormwater Modeling - Since 1986


Modeling Marlee Float skimmers in HydroCAD

Marlee Float is a line of skimmer outlet devices, designed to produce a relatively constant flow rate regardless of water surface elevation.  When used as an outlet control device on a detention pond, this behavior increases the storage utilization, allowing the use of a smaller storage volume while still attaining the same discharge rate.

Designed and manufactured by SW FeeSaver of Greenville, South Carolina, the Marlee Float is available in range of sizes to suit a wide range of flow requirements.

Modeling Marlee Float skimmers in HydroCAD

The objective of the Marlee Float skimmers is to produce a relatively constant flow rate regardless of water surface elevation.  This behavior is illustrated in the stage-discharge curves shown below.

The unique discharge characteristics of the Marlee Float are easily modeled in HydroCAD by using a special outlet device.  With the release of HydroCAD 10.0 build 14, Marlee Float rating curves are preinstalled with HydroCAD, making the modeling these devices even easier:

1) Create a special outlet
2) Click "Load From File", open the Marlee Float folder, and select the desired model and orifice size.
3) Set the Invert Elevation to the water surface elevation where flow will start to occur.
