 $$K = \frac{Q_{submerged}}{Q_{free}} = \left [ 1- \left ( \frac{h2}{h1} \right)^n \right]^{0.385}$$
 
 With:

 - \(h_1\) the upstream water level above the weir crest
 - \(h_2\) the downstream water level above the weir crest
 - \(n\) the exponent in free flow relationships (rectangular=1.5, triangular=2.5, parabolic=2)
