Includes bibliographical references (pages 22 to 23). "The design storm concept is well established in Canadian urban drainage practice, although some confusion results from an incomplete definition of design storms and their applications. To remedy this situation, it is recommended that design storms be developed for a wide range of return periods; these storms should be based on local AES rainfall data, given for both the rational method and hydrograph model applications, and supplemented by specifications of the computational procedure and normal antecedent conditions. The design storm hyetograph would be defined for a particular region, return period and catchment time constant and, when applied in conjunction with the specified computational procedure and antecedent conditions, would produce a peak flow of approximately the same return period as that of the design storm. None of the existing design storms has all these features but further work on temporal distributions and antecedent conditions would result in an acceptable set of design storms"--Synopsis.
