<br />\)( ~" <br /> <br />In contrast to results at Kiowa Ck nr Elbert as discussed above, Table 1 indicates good <br />agreement between HEC-I and USGS discharge data for Kiowa Ck at Kiowa. Those results <br />were derived by inputting (into HEC-l) reduced rainfall for the two sub-basins above Elbert as <br />discussed above, By modeling the basin as such, Cell A-3 could be isolated in the model so its <br />affect on producing the USGS discharge at Kiowa could be evaluated, <br /> <br />It is important to note that the rainfall distribution for Cell A-3 was the same as that for cell A- <br />2 (8 in morning rain separated by a period of 3 hours with no rain, and then another 16 in of <br />rain). Thus, the peak discharge for Kiowa Ck at Kiowa (i.e" the peak discharge at Kiowa <br />includes the routed 43,500 cfs from the two sub-basins above Elbert) was driven by the afternoon <br />rain of 16 in vs the total of 24 in. Such a distribution applied to HEC-I adds additional evidence <br />to Mr, John Henz's preliminary evaluation that Cell A-3 had both morning and afternoon dumps, <br /> <br />DISCUSSION <br /> <br />The results ofthis study are not intended to prove that the May 30-31, 1935 A-2 and A-3 storm <br />cells are not valid; rather, the results are intended to augment other evidence as to such, It was <br />felt that although the study was based on a low level of modeling, the results still "raise a flag" as <br />to the accuracy (both in rainfall amount and spatial distribution) of the documented storm cells. <br />More accurate results are likely possible from a large dissection of the Drainage Areas resulting <br />in numerous sub-basins. In that way, detailed hydrologic characteristics of the basin can be more <br />accurately represented, and various rainfall amounts falling on specific areas ofthe basin can be <br />represented, <br /> <br />In addition, verification of rainfall amount via 'reverse modeling" on very small basins (DA < 5 <br />sqmi) and based on paleohydrology (as stated in the Project Scope of Work) will add invaluable <br />information to the analysis. This report provides additional support to the importance of the <br />small basin paleohydrologylhydrologic modeling effort. It can be seen that small basin <br />paleohydrologylhydrologic modeling could "pinpoint" both rainfall depth and location, thereby <br />adding to information on historic storms, <br />
