ThirstyDuck, Ltd. is pleased to announce its model ER-200 buoyant flow control device (BFD) has been approved for use by the Florida Department of Transportation on production projects with the approval of the State Hydraulics Office.
- Buoyant Flow Control Device Types (single restriction, dual restriction and hybrid types)
- Development of rating curves (stage vs. discharge) for each type BFD
- Weir flow to orifice flow transition
- Determining the point of restriction
- Free discharge condition
- Tailwater conditions
- Spreadsheet/tabular solutions
- Modeling techniques
- Inserting rating curves into ICPR, PONDS, HydroCad, TR-20, HEC-HMS
- Dynamic tailwater modeling (families of rating curves)
- Manhole and pipe losses (inclusion in rating curve vs. individual nodes and reaches)
- Using the constant flow device option in HydroCad
- Factors affecting system savings
- Inflow vs. outflow rate
- system flux
- Construction Details
- Box type and size
- Inverted siphons
- Emergency overflow devices
- Buoyancy and ballasting
- Vegetation control
- Venting and Air release
The course objectives will be:
- Understand how the ER type buoyant flow control device operates
- Understand how the ER type BFD can be used to minimize detention volume
- Understanding the device variations and identification of situations suited for each variation
- Learn to compute the stage vs. discharge relationship (rating curve) for each device type variation in free discharge and tailwater conditions
- Learn to insert rating curves into popular modeling software such as ICPR, Ponds, HydroCad
- Learn to model the ER type BFD for single and multiple storm events.
- Identify design conditions and other factors which affect efficiency and potential system savings
- Learn to calculate required buoyancy
- Understand and identify construction design details required for proper operation and maintenance.
