<br />General Discussion <br />In the preceeding part of this section, the procedures <br />and results of the hydrology are presented for this study. <br />It is interesting to note comparative analysis and results <br />using other hydrological procedures. <br /> <br />1.) Rational Method <br />The rational method involves solving the equation: <br />Q ; CiA <br />where Q ; maximum rate of runoff ln cfs <br />C ; runoff coefficient <br />1 ; intensity of rainfall ln inches per hour <br />A ; area of Basin in acres <br /> <br />The coefficient C is selected as 0.5 representing the <br />ratio of maximum rate of runoff from the area to the average <br />rate of rainfall intensity including the effects of infiltra- <br />tion, surface storage, and rainfall intensity. The rainfall <br />intensity is selected as the average intensity for a 6-hour <br />storm duration and lOO-year frequency storm which is 1.5 in/hr. <br />therefore: <br />Q ; 0.5 x 1.5 x 19.5 x 640 <br />; 9360 cfs (6 hr. - 100 yr. frequency storm) <br /> <br />- 3(,- <br />
