WebFeb 3, 2013 · Similar to the case of Cipolletti weir, the noise-free computed flow rate for the parabolic weir notch has the same outcome as the model solution for both 60 and 100 feet inheight. Once a random noise higher than 100% or even 300% is added to the system, the flow rate can still be distinguished fairly easy, as Figure 4(a) and Figure 4(b) suggest.
