Includes bibliographical references (p. 10). "A recursion formula has been derived which can be used for converting unit hydrographs either from short duration to long duration or from long duration to short duration. Thus, an alternative to developing an S-hydrograph for this purpose is proposed. Examples on the use of the formula have been provided. A technique has also been suggested to eliminate oscillations in the S-hydrograph and derived unit hydrograph"--Abstract, p. v. Text in English and French.
