Flood hydrograph estimate from a unit hydorgraph / A.G. Smith. : En39-28/1988E-PDF

"The Unit Hydrograph concept was used to simulate peak flows for two streamflow stations, Barlow Creek near Quesnel and Lillooet River near Pemberton. The unit hydrographs were derived from eleven rain-storm events for Barlow Creek and sixteen for Lillooet River. A duration time of twenty-four hours was considered acceptable as precipitation data for Quesnel Airport and Pemberton B.C.F.S. stations were recorded only on a daily basis. Two simulated peaks are presented for each station and when increased by the maximum suggested twenty percent are within three percent of the published values. It is recommended that the unit hydrograph be used, in locations where adequate precipitation data is available, to simulate the extreme peak flows at stations where the flood event has not been recorded"--Summary, p. iii.
