The discussion ialk'tes that tbe model was calilnIed usm, low Oow water surface profile daIa. The model should be chec:bd apiDst high walei' marks to verify projectiollS of the 100-year flood. 72. Model Cahoratioa. 1hc source of data for c:alibntioll sboald be fully described. iWuding date of the lcnown measured water surface profile. Please include in text. 73. Model CalibratioD. In additiOD to the table Iistin8 a complIisoll of COO'po.l1Ied and lcnown WSEL, it would be belpftll to see a plot of ~utt;d and known (mnwred, CRP. aDd lOO-year profile) water surface profiles to see bow wen the model is eaIihrated, rather dwl simply stating calibration is reasonable. 74. ModeliDg Parametm. Text indicates that tbe mnimum berm beight modeled was about 6 feet, but drawing (PIatc 3) shows bem1 height to be a mllTimum of 8 feet. Drawing should be corrected to reflect coDditioDS 1$ modeled or else HEC.2 model needs to be changed. 7S. Flood PWn Analysis.
