"This is a modified version of a paper which was approved for publication in the Proceedings of the 6th Canadian Hydrotechnical Conference, June 1983. This manuscript has also been submitted to Canadian Journal of Civil Engineering and the contents are subject to change." Includes bibliographical references (pages 29 to 31). "The design storm concept is well established in Canadian urban drainage practice, but appropriate use is hindered by an incomplete definition of design storms and their applications. To remedy this situation, it is recommended that design storms be developed for various regions and a wide range of durations and return periods; these storms should be based on local HAES rainfall data, given for both the rational method and hydrograph model applications, and supplemented by specifications of the computational procedure and normal antecedent conditions. Such design storms would produce peak flows of approximately the same return period as that of the design storm. None of the existing design storms has all these features but an acceptable set of design storms could be developed using existing Canadian data"--Page 2. Includes summary in French. Storm sewers.
