A <br />single basin HEC-I analysis was performed using SCS methodology. A composite Curve Number was estimated <br />from county soils maps, and a basin lag time was estimated using the method found in the SCS TR -55 manual. <br />The rainfall distribution input to the model was the SCS Type II. Again, the results from this analysis were only <br />used as a reasonableness check of the results from the two previous methods. The HEC-I output file is included at <br />the end of this appendix. <br /> <br />Summary: The peak flow resnlts for the Old Soldier River are presented in Figure 2 and are estimates obtained <br />from three different hydrologic methodologies. The three methods yielded results which compare reasonably well <br />with each other. The regional regression equations used for this site appear to give results that are more <br />conservative than the statewide regression equations. The Missouri River peak discharges assumed for the <br />California Bend site were confirmed by the Corps and are also presented in Figure 2. <br />
