The CurveFit computer program analyzes the input data using a library of 25 equations. 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 100 -year flow calculations. <br />3.4 Hydrologic Findings <br />Table 3 shows the results of this analysis in tabular form.
