Abstract
Polynomial weirs can be applied in agricultural and municipal engineering to produce a wide range of head-discharge behavior, including the proportional (linear) characteristics of the Sutro weir. This note describes a method to determine the head-discharge equations of sharp-crested weirs with openings defined by polynomials of any order . Examples of behavior of fourth-order polynomial weirs are discussed.
