The barrier el~ation map in Hk/R 55A was used to adjust the raster fields of <br />"non-orographic" vdfues to sea leveL'~ Was this map also usedfor its intended pUlpose" <br />ie. moisture depletiof'? (Tomlinson) . <br />Group agreed :question was answered. HNfR 55A PMP values included moistun:~ <br />barrier depleti~n. <br />I <br />1 <br />I <br />11. The BOSS softw~re package has demonstrated errors in its calculation of within <br />storm isohyetal valu,es (personal communication, Ellen Faulkner, ]t;/ead and Hunt <br />Engineering, June, ~999). The soft.flare sometimes produces rainfall volumes larger <br />than the Plr/P for ai,eas smaller that the PMS. Were tests conducted to demonstrate' <br />that this error did nOf occur? (Tomlinson) <br /> <br />I <br />1 <br /> <br />No longer app:licable as per Dr. Tomlinson. <br />1 <br />I <br />1 <br />1 <br /> <br />12. The chronology for the temporal variations were based on hourly percetrtage' <br />I <br />contributions from PRll},tfR 52. Were these variations derived from the same 29' <br />storms used to derive the withinlwithout storm curves in HlYfR 52? How do they <br />compare. to the largest storms which are transpositionahle to the Cherry Creek <br />drainage basin? qlicit/y, what other chronologies can be used, how would th,ey be <br />derived, and what criteria is used to determine that they are permissible? (Tomlinson) <br />, 1 <br />, <br />1 <br />Group agreed this does not impact the hydrologic modeling of the PMF. <br />I <br />I <br />i <br /> <br />1 <br />1 <br />1 <br />13. Paragraph 2 ,of ~he 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"? (TJmIinson) <br />I <br />I <br />, <br />Antecedent stlldy appljed some of the methodolgy from Hydro 45 and ex:te~nded <br />the area. Group agreed this was satisfactory answer. <br />I <br /> <br />14. The last sentence in the same paragraph state that "Most of the statimcaJ <br />relationships develap~d for HYDRO 45 were not investigated in the present study due <br />to time canstraints".! What were the time constraints and what additional statimcal <br />relationships wauld ~e been perfarmed had the time constraints not been present? <br />(Tomlinson) , <br /> <br />. .
