Polynomial weirs are weirs with openings defined by polynomial equations. The general head-discharge equation of polynomial weirs was derived, from first principles, by Raouf E Baddour (2008). This formulation is allowing polynomial weirs to be incorporated in many applications, including:
1. Management of stormwater quantity and quality at the outlet of detention ponds.
2. Redesign compound weirs as polynomial weirs to eliminate transitional instabilities.
3. Design polynomial skimmer weirs, which have significantly enhanced skimming properties compared to rectangular and triangular weirs.
4. Design multistage polynomial weir systems to replace stoplogs at the outlets of small lakes and reservoirs.
