WebQ = Peak discharge, cfs c = Rational method runoff coefficient i = Rainfall intensity, inch/hour A = Drainage area, acre Note that our calculation allows you to use a variety of units. The Rational method runoff coefficient (c) is a function of the soil type and drainage basin slope. A simplified table is shown below. WebYou can immediately see that the mid and lower flows (exceeded about 40% (or 0.4) of the year) are relatively similar in each year, but the larger flows exhibit quite a bit of variability. In 2007 the highest flow of the year …
