Use the USGS regression equation [Eq.] to compute the 5-yr peak flow for a 4-ac Tallahassee catchment that is 95% impervious. Compare your answer with the value computed in Example 6-6. The reason for the large discrepancy is that the regression equations were developed for much larger catchments (the smallest being 0.21 mi2) and probably do not apply to a 4-ac catchment.
