Burlington, Ont. : Hydraulics Division, National Water Research Institute, Canada Centre for Inland Waters, 1985. ii, 9 p. : ill. NWRI contribution ; 85-08 "May 1985". "This manuscript will be presented at the 21st Congress of the International Association for Hydraulic Research in Melbourne, Australia, August 1985". Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references. "Organizers of the 21st Congress of the International Association for Hydraulic Research, requested specific information on hydraulic losses at junctions in storm sewers when operating in a surcharged condition. This paper, using data developed for a client, provides specific information on these losses and provides methods to reduce such losses. Head losses, which are unnecessarily large owing to poor design, increase the costs of excavation or increase flooding frequency. A typical practical example is given. All sewer system designers should adopt the benching designs indicated in the report"--Management perspective, p. i.
