The barrier elevation mop in HMR 55A was used to adjust the raster fields of <br />"non-orographic" values to sea leveL"' Was this map also usedfor its intended purpose, <br />i.e. moisture depletion? (Tomlinson) . <br />Group agreed question was answered. HMR 55A PMP values included moisture <br />barrier depletion. <br /> <br />11. The BOSS software package has demonstrated errors in its calculation of within <br />storm isohyetal values (personal communication, Ellen Faulkner, j}[ead and Hunt <br />Engineering, June, 1999). The software sometimiis produces rainfall volumes larger <br />than the PMP for areas smaller thit the PMS. Were tests conducted to demonstrate <br />that this error did not occur? (Tomlinson) <br /> <br />No longer ap'plicable as per Dr. Tomlinson. <br /> <br />12. The chronology for the temporal variations were based on hourly percentage <br />contributions from PRHMR 52. Were these variations derived from the same 29 <br />storms used to derive the withinlwithout storm curves in Jlj}[R 52? How do they <br />compare to the largest storms which are transpositionahle to the Cherry Creek <br />drainage basin? Explicitly, what other chronologies can be used, how would they be <br />derived, and what criteria is used to determine that they are permissible? (Tomlinson) <br /> <br />Group agreed this does not impact the hydrologic modeling of the P.MF. <br /> <br />13. Paragraph 2 of the introduction states that " This study also supplements, to a <br />limited extent, NOAA Technical Memorandum, NWS Hydro 45..." What is meant by <br />"limited extent"? (Tomlinson) <br /> <br />Antecedent study applied some of the methodolgy from Hydro 4S and extended <br />the area. Group agreed this was satisfactory answer. <br /> <br />14. The last ~entence in the same paragraph state that "Most of the statistical <br />relationships developed for HYDRO 45 were not investigated in the present study due <br />to time constraints". What were the time constraints and what additional statistical <br />relationships would have been performed had the time constraints not been present? <br />(Tomlinson) <br /> <br />. .Topics~~1J1IIy 1999 Tedurict.z Muting 3 <br /> <br />-.. - - - - '.- -... - .~ <br />- - '; '-=--:"-:--:::"::":-:--";- ~.~.:;.~. :"-~~~-=::-." <br /> <br />"_n_..
