Figure 27. Minimum Flow Ratios vs. ADWF
12 Due to attenuation, it should be expected that sites with larger flow volumes should not have quite the peak-to-average and
low-to-average flow ratios as sites with lesser flow volumes, which is why the WEF typical trend lines slope closer to 1.0 as the
ADWF increases, as shown in the figure.
