CER72-73EFS-VY13.December 1, 1972.Includes bibliographical references (pages 11-12).OWRR project no. B-064-COLO (CSU Project 31-1372-1632), period July 1, 1971 to June 30, 1972 and extended to December 31, 1972.The work upon which this report is based was supported (in part) by funds provided by the U. S. Department of Interior, Office of Water Resources Research as authorized by the Water Resources Research Act of 1964 and pursuant to Grant Agreement No. 14-31-0001-3565.Circulating copy deaccessioned 2020.The flood response of a small watershed to flood producing rainfall was investigated in several ways. First flood hydrographs measured on small pristine watersheds were assembled along with the causal rainfall, antecedent rainfall, and a number of physiographic parameters of the watershed. Research has verified the validity of the application of the kinematic wave theory for computing the hydrograph of runoff from small watersheds. Research was carried out on deriving unit hydrographs from observed rainfall and runoff. A study was made of correlation of various methods of defining the response time of a watershed. A low pass filter method was used to remove oscillations from some of the derived unit hydrographs.Grant Agreement No. 14-31-0001-3565
