The <br />output displays the constants and the correlation values for each equation. The best .fit equations <br />are chosen based on the correlation value closest to 1.0. For this report an additional step was <br />included in the selection of an equation. Of all the possible equations which fell within a <br />correlation value greater than 0.95, the least complex equation was chosen. The same equation <br />format was selected for both the 50-year and lOO-year flow calculations. <br /> <br />3.4 HvdrolOlZic Findimzs <br /> <br />Table 3 shows the results of this analysis in tabular form. Figure 5 shows the relationship <br />between 50-year or lOO-year flow and drainage area, as described by these equations, in graphical <br />form. <br /> <br />11 <br />
